Diacylglycerol kinase accessory domain (presumed); Diacylglycerol (DAG) is a second messenger that acts as a protein kinase C activator. DAG can be produced from the hydrolysis of phosphatidylinositol 4,5-bisphosphate (PIP2) by a phosphoinositide-specific phospholipase C and by the degradation of phosphatidylcholine (PC) by a phospholipase C or the concerted actions of phospholipase D and phosphatidate phosphohydrolase. This domain might either be an accessory domain or else contribute to the catalytic domain. Bacterial homologues are known. : Pssm-ID: 214486 Cd Length: 160 Bit Score: 273.06 E-value: 6.00e-85

55-151 | 1.33e-57 | |||
Type 2 Diacylglycerol kinase Pleckstrin homology (PH) domain; DGK (also called DAGK) catalyzes the conversion of diacylglycerol (DAG) to phosphatidic acid (PA) utilizing ATP as a source of the phosphate. In non-stimulated cells, DGK activity is low and DAG is used for glycerophospholipid biosynthesis. Upon receptor activation of the phosphoinositide pathway, DGK activity increases which drives the conversion of DAG to PA. DGK acts as a switch by terminating the signalling of one lipid while simultaneously activating signalling by another. There are 9 mammalian DGK isoforms all with conserved catalytic domains and two cysteine rich domains. These are further classified into 5 groups according to the presence of additional functional domains and substrate specificity: Type 1 - DGK-alpha, DGK-beta, DGK-gamma - contain EF-hand motifs and a recoverin homology domain; Type 2 - DGK-delta, DGK-eta, and DGK-kappa- contain a pleckstrin homology domain, two cysteine-rich zinc finger-like structures, and a separated catalytic region; Type 3 - DGK-epsilon - has specificity for arachidonate-containing DAG; Type 4 - DGK-zeta, DGK-iota- contain a MARCKS homology domain, ankyrin repeats, a C-terminal nuclear localization signal, and a PDZ-binding motif; Type 5 - DGK-theta - contains a third cysteine-rich domain, a pleckstrin homology domain and a proline rich region. The type 2 DGKs are present as part of this Metazoan DGK hierarchy. They have a N-terminal PH domain, two cysteine rich domains, followed by bipartite catalytic domains, and a C-terminal SAM domain. Their catalytic domains and perhaps other DGK catalytic domains may function as two independent units in a coordinated fashion. They may also require other motifs for maximal activity because several DGK catalytic domains have very little DAG kinase activity when expressed as isolated subunits. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes. : Pssm-ID: 270093 Cd Length: 97 Bit Score: 193.38 E-value: 1.33e-57

first protein kinase C conserved region 1 (C1 domain) found in diacylglycerol kinase delta (DAG kinase delta) and similar proteins; Diacylglycerol (DAG) kinase (EC 2.7.1.107) is a lipid kinase that phosphorylates diacylglycerol to form phosphatidic acid. DAG kinase delta, also called 130 kDa diacylglycerol kinase, or diglyceride kinase delta (DGK-delta), is a residential lipid kinase in the endoplasmic reticulum. It promotes lipogenesis and is involved in triglyceride biosynthesis. It is classified as a type II DAG kinase (DGK), containing pleckstrin homology (PH) and sterile alpha motifs (SAM) domains, in addition to C1 and catalytic domains that are present in all DGKs. The SAM domain mediates oligomerization of type II DGKs. DAG kinase delta contains two copies of the C1 domain. This model corresponds to the first one. The C1 domain is a cysteine-rich zinc binding domain that does not bind DNA nor possess structural similarity to conventional zinc finger domains; it contains two separate Zn(2+)-binding sites. : Pssm-ID: 410397 Cd Length: 85 Bit Score: 182.61 E-value: 4.66e-54

1143-1207 | 2.93e-43 | |||
SAM domain of diacylglycerol kinase delta; SAM (sterile alpha motif) domain of DGK-delta subfamily proteins is a protein-protein interaction domain. Proteins of this subfamily are multidomain diacylglycerol kinases with a SAM domain located at the C-terminus. DGK-delta proteins participate in signal transduction. They regulate the level of second messengers such as diacylglycerol and phosphatidic acid. In particular DGK-delta is involved in the regulation of clathrin-dependent endocytosis. The SAM domain of DGK-delta proteins can form high molecular weight homooligomers through head-to-tail interactions as well as heterooligomers with the SAM domain of DGK-eta proteins. The oligomerization plays a role in the regulation of the DGK-delta intracellular localization: it inhibits the translocation of the protein to the plasma membrane from the cytoplasm. The SAM domain also can bind Zn at multiple (not conserved) sites driving the formation of highly ordered large sheets of polymers, thus suggesting that Zn may play important role in the function of DCK-delta. : Pssm-ID: 188974 Cd Length: 65 Bit Score: 151.26 E-value: 2.93e-43

Type 2 Diacylglycerol kinase Pleckstrin homology (PH) domain; DGK (also called DAGK) catalyzes the conversion of diacylglycerol (DAG) to phosphatidic acid (PA) utilizing ATP as a source of the phosphate. In non-stimulated cells, DGK activity is low and DAG is used for glycerophospholipid biosynthesis. Upon receptor activation of the phosphoinositide pathway, DGK activity increases which drives the conversion of DAG to PA. DGK acts as a switch by terminating the signalling of one lipid while simultaneously activating signalling by another. There are 9 mammalian DGK isoforms all with conserved catalytic domains and two cysteine rich domains. These are further classified into 5 groups according to the presence of additional functional domains and substrate specificity: Type 1 - DGK-alpha, DGK-beta, DGK-gamma - contain EF-hand motifs and a recoverin homology domain; Type 2 - DGK-delta, DGK-eta, and DGK-kappa- contain a pleckstrin homology domain, two cysteine-rich zinc finger-like structures, and a separated catalytic region; Type 3 - DGK-epsilon - has specificity for arachidonate-containing DAG; Type 4 - DGK-zeta, DGK-iota- contain a MARCKS homology domain, ankyrin repeats, a C-terminal nuclear localization signal, and a PDZ-binding motif; Type 5 - DGK-theta - contains a third cysteine-rich domain, a pleckstrin homology domain and a proline rich region. The type 2 DGKs are present as part of this Metazoan DGK hierarchy. They have a N-terminal PH domain, two cysteine rich domains, followed by bipartite catalytic domains, and a C-terminal SAM domain. Their catalytic domains and perhaps other DGK catalytic domains may function as two independent units in a coordinated fashion. They may also require other motifs for maximal activity because several DGK catalytic domains have very little DAG kinase activity when expressed as isolated subunits. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane.

DAG kinase alpha, also called 80 kDa DAG kinase, or diglyceride kinase alpha (DGK-alpha), is active upon cell stimulation, initiating the resynthesis of phosphatidylinositols and attenuating protein kinase C activity. DAG kinase beta, also called 90 kDa DAG kinase, or diglyceride kinase beta (DGK-beta), exhibits high phosphorylation activity for long-chain diacylglycerols. DAG kinase gamma, also called diglyceride kinase gamma (DGK-gamma), reverses the normal flow of glycerolipid biosynthesis by phosphorylating diacylglycerol back to phosphatidic acid. Members of this family contain two copies of the C1 domain. This model corresponds to the first one. DGK-alpha contains atypical C1 domains, while DGK-beta and DGK-gamma contain typical C1 domains that bind DAG and phorbol esters. The C1 domain is a cysteine-rich zinc binding domain that does not bind DNA nor possess structural similarity to conventional zinc finger domains; it contains two separate Zn(2+)-binding sites.

Tandem PH-domain-containing protein 2 Pleckstrin homology (PH) domain; The binding of TAPP2 (also called PLEKHA2) adaptors to PtdIns(3,4)P(2), but not PI(3,4, 5)P3, function as negative regulators of insulin and PI3K signalling pathways (i.e. TAPP/utrophin/syntrophin complex). TAPP2 contains two sequential PH domains in which the C-terminal PH domain specifically binds PtdIns(3,4)P2 with high affinity. The N-terminal PH domain does not interact with any phosphoinositide tested. They also contain a C-terminal PDZ-binding motif that interacts with several PDZ-binding proteins, including PTPN13 (known previously as PTPL1 or FAP-1) as well as the scaffolding proteins MUPP1 (multiple PDZ-domain-containing protein 1), syntrophin and utrophin. The members here are most sequence similar to TAPP2 proteins, but may not be actual TAPP2 proteins. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

ArfGAP with coiled-coil, ankyrin repeat and PH domains Pleckstrin homology (PH) domain; ACAP (also called centaurin beta) functions both as a Rab35 effector and as an Arf6-GTPase-activating protein (GAP) by which it controls actin remodeling and membrane trafficking. ACAP contain an NH2-terminal bin/amphiphysin/Rvs (BAR) domain, a phospholipid-binding domain, a PH domain, a GAP domain, and four ankyrin repeats. The AZAPs constitute a family of Arf GAPs that are characterized by an NH2-terminal pleckstrin homology (PH) domain and a central Arf GAP domain followed by two or more ankyrin repeats. On the basis of sequence and domain organization, the AZAP family is further subdivided into four subfamilies: 1) the ACAPs contain an NH2-terminal bin/amphiphysin/Rvs (BAR) domain (a phospholipid-binding domain that is thought to sense membrane curvature), a single PH domain followed by the GAP domain, and four ankyrin repeats; 2) the ASAPs also contain an NH2-terminal BAR domain, the tandem PH domain/GAP domain, three ankyrin repeats, two proline-rich regions, and a COOH-terminal Src homology 3 domain; 3) the AGAPs contain an NH2-terminal GTPase-like domain (GLD), a split PH domain, and the GAP domain followed by four ankyrin repeats; and 4) the ARAPs contain both an Arf GAP domain and a Rho GAP domain, as well as an NH2-terminal sterile-a motif (SAM), a proline-rich region, a GTPase-binding domain, and five PH domains.

ATG26 in decane metabolism and autophagy. There are 32 known autophagy-related (ATG) proteins, 17 are components of the core autophagic machinery essential for all autophagy-related pathways and 15 are the additional components required only for certain pathways or species. The core autophagic machinery includes 1) the ATG9 cycling system (ATG1, ATG2, ATG9, ATG13, ATG18, and ATG27), 2) the phosphatidylinositol 3-kinase complex (ATG6/VPS30, ATG14, VPS15, and ATG34), and 3) the ubiquitin-like protein system (ATG3, ATG4, ATG5, ATG7, ATG8, ATG10, ATG12, and ATG16). Less is known about how the core machinery is adapted or modulated with additional components to accommodate the nonselective sequestration of bulk cytosol (autophagosome formation) or selective sequestration of specific cargos (Cvt vesicle, pexophagosome, or bacteria-containing autophagosome formation). The pexophagosome-specific additions include the ATG30-ATG11-ATG17 receptor-adaptors complex, the coiled-coil protein ATG25, and the sterol glucosyltransferase ATG26.

Fungal proteins Pleckstrin homology (PH) domain, repeat 1; The functions of these fungal proteins are unknown, but they all contain 2 PH domains. This cd represents the first PH repeat. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

SAM domain of EPH family of tyrosine kinase receptors; SAM (sterile alpha motif) domain of EPH (erythropoietin-producing hepatocyte) family of receptor tyrosine kinases is a C-terminal signal transduction module located in the cytoplasmic region of these receptors. SAM appears to mediate cell-cell initiated signal transduction via binding proteins to a conserved tyrosine that is phosphorylated. In some cases the SAM domain mediates homodimerization/oligomerization and plays a role in the clustering process necessary for signaling. EPH kinases are the largest family of receptor tyrosine kinases. They are classified into two groups based on their abilities to bind ephrin-A and ephrin-B ligands. The EPH receptors are involved in regulation of cell movement, shape, and attachment during embryonic development; they control cell-cell interactions in the vascular, nervous, epithelial, and immune systems, and in many tumors.

PKC-epsilon has been shown to behave as an oncoprotein. Its overexpression contributes to neoplastic transformation depending on the cell type. It contributes to oncogenesis by inducing disordered cell growth and inhibiting cell death. It also plays a role in tumor invasion and metastasis. PKC-epsilon has also been found to confer cardioprotection against ischemia and reperfusion-mediated damage. Other cellular functions include the regulation of gene expression, cell adhesion, and cell motility. PKC-eta is predominantly expressed in squamous epithelia, where it plays a crucial role in the signaling of cell-type specific differentiation. It is also expressed in pro-B cells and early-stage thymocytes, and acts as a key regulator in early B-cell development.

They have a N-terminal motor domain, followed by a coiled-coil domain, and a C-terminal PH domain. KIF1A adopts a monomeric form in vitro, but acts as a processive dimer in vivo. KIF1B has alternatively spliced isoforms distinguished by the presence or absence of insertion sequences in the conserved amino-terminal region of the protein; this results in their different motor activities. KIF1A and KIF1B bind to RAB3 proteins through the adaptor protein mitogen-activated protein kinase (MAPK) -activating death domain (MADD; also calledDENN), which was first identified as a RAB3 guanine nucleotide exchange factor (GEF).

first protein kinase C conserved region 1 (C1 domain) found in type V diacylglycerol kinase, DAG kinase theta, and similar proteins; Diacylglycerol (DAG) kinase (EC 2.7.1.107) is a lipid kinase that phosphorylates diacylglycerol to form phosphatidic acid. DAG kinase theta, also called diglyceride kinase theta (DGK-theta), is the only isoform classified as type V; it contains a pleckstrin homology (PH)-like domain and an additional C1 domain, compared to other DGKs. It may regulate the activity of protein kinase C by controlling the balance between the two signaling lipids, diacylglycerol and phosphatidic acid. DAG kinase theta contains three copies of the C1 domain. This model corresponds to the first one. The C1 domain is a cysteine-rich zinc binding domain that does not bind DNA nor possess structural similarity to conventional zinc finger domains; it contains two separate Zn(2+)-binding sites.

SAM domain of ASZ1 subfamily; SAM (sterile alpha motif) domain of ASZ1 (Ankyrin, SAM, leucine Zipper) also known as GASZ (Germ cell-specific Ankyrin, SAM, leucine Zipper) subfamily is a potential protein-protein interaction domain. Proteins of this group are involved in the repression of transposable elements during spermatogenesis, oogenesis, and preimplantation embryogenesis. They support synthesis of PIWI-interacting RNA via association with some PIWI proteins, such as MILI and MIWI. This association is required for initiation and maintenance of retrotransposon repression during the meiosis. In mice lacking ASZ1, DNA damage and delayed germ cell maturation was observed due to retrotransposons releasing from their repressed state.

SAM domain of MLTK subfamily; SAM (sterile alpha motif) domain of MLTK subfamily is a protein-protein interaction domain. Besides SAM domain, these proteins have N-terminal protein tyrosine kinase domain and leucine-zipper motif. Proteins of this group act as mitogen-activated protein triple kinase in a number of MAPK cascades. They can be activated by autophosphorylation in response to stress signals. MLTK-alpha is known to phosphorylate histone H3. In mammals, MLTKs participate in the activation of the JNK/SAPK, p38, ERK5 pathways, the transcriptional factor NF-kB, in the regulation of the cell cycle checkpoint, and in the induction of apoptosis in a hepatoma cell line. Some members of this subfamily are proto-oncogenes, thus MLTK-alpha is involved in neoplasmic cell transformation and/or skin cancer development in athymic nude mice. Based on in vivo coprecipitation experiments in mammalian cells, it has been demonstrated that MLTK proteins might form homodimers/oligomers via their SAM domains.

Sesquipedalian family Pleckstrin homology (PH) domain; The sesquipedalian family has 2 mammalian members: Ses1 and Ses2, which are also callled 7 kDa inositol polyphosphate phosphatase-interacting protein 1 and 2. They play a role in endocytic trafficking and are required for receptor recycling from endosomes, both to the trans-Golgi network and the plasma membrane. Members of this family form homodimers and heterodimers. Sesquipedalian interacts with inositol polyphosphate 5-phosphatase OCRL-1 (INPP5F) also known as Lowe oculocerebrorenal syndrome protein, a phosphatase enzyme that is involved in actin polymerization and is found in the trans-Golgi network and INPP5B. Sesquipedalian contains a single PH domain. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

They act as GTPase activators for the Rac-type GTPases by converting them to an inactive GDP-bound state and control actin remodeling by inactivating Rac downstream of Rho leading to suppress leading edge protrusion and promotes cell retraction to achieve cellular polarity and are able to suppress RAC1 and CDC42 activity in vitro. Overexpression of these proteins induces cell rounding with partial or complete disruption of actin stress fibers and formation of membrane ruffles, lamellipodia, and filopodia. This hierarchy contains RhoGAP22, RhoGAP24, and RhoGAP25.

C1 has a globular fold with two separate Zn(2+)-binding sites. It was originally discovered as lipid-binding modules in protein kinase C (PKC) isoforms. C1 domains that bind and respond to phorbol esters (PE) and diacylglycerol (DAG) are referred to as typical, and those that do not respond to PE and DAG are deemed atypical. A C1 domain may also be referred to as PKC or non-PKC C1, based on the parent protein's activity. Most C1 domain-containing non-PKC proteins act as lipid kinases and scaffolds, except PKD which acts as a protein kinase.

PKCs undergo three phosphorylations in order to take mature forms. In addition, cPKCs depend on calcium, DAG (1,2-diacylglycerol), and in most cases, phosphatidylserine (PS) for activation. nPKCs are calcium-independent, but require DAG and PS for activity, while atypical PKCs (aPKCs) only require PS. PKCs phosphorylate and modify the activities of a wide variety of cellular proteins including receptors, enzymes, cytoskeletal proteins, transcription factors, and other kinases. They play a central role in signal transduction pathways that regulate cell migration and polarity, proliferation, differentiation, and apoptosis. This family includes classical PKCs (cPKCs) and novel PKCs (nPKCs). There are four cPKC isoforms (named alpha, betaI, betaII, and gamma) and four nPKC isoforms (delta, epsilon, eta, and theta). Members of this family contain two copies of the C1 domain. This model corresponds to the first one.

General Receptor for Phosphoinositides-1-like Pleckstrin homology (PH) domain; GRP1/cytohesin3 and the related proteins ARNO (ARF nucleotide-binding site opener)/cytohesin-2 and cytohesin-1 are ARF exchange factors that contain a pleckstrin homology (PH) domain thought to target these proteins to cell membranes through binding polyphosphoinositides. The PH domains of all three proteins exhibit relatively high affinity for PtdIns(3,4,5)P3. Within the Grp1 family, diglycine (2G) and triglycine (3G) splice variants, differing only in the number of glycine residues in the PH domain, strongly influence the affinity and specificity for phosphoinositides. The 2G variants selectively bind PtdIns(3,4,5)P3 with high affinity,the 3G variants bind PtdIns(3,4,5)P3 with about 30-fold lower affinity and require the polybasic region for plasma membrane targeting. These ARF-GEFs share a common, tripartite structure consisting of an N-terminal coiled-coil domain, a central domain with homology to the yeast protein Sec7, a PH domain, and a C-terminal polybasic region. The Sec7 domain is autoinhibited by conserved elements proximal to the PH domain. GRP1 binds to the DNA binding domain of certain nuclear receptors (TRalpha, TRbeta, AR, ER, but not RXR), and can repress thyroid hormone receptor (TR)-mediated transactivation by decreasing TR-complex formation on thyroid hormone response elements. ARNO promotes sequential activation of Arf6, Cdc42 and Rac1 and insulin secretion. Cytohesin acts as a PI 3-kinase effector mediating biological responses including cell spreading and adhesion, chemotaxis, protein trafficking, and cytoskeletal rearrangements, only some of which appear to depend on their ability to activate ARFs. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner.

174-213 | 1.19e-05 | ||||
protein kinase C conserved region 1 (C1 domain) found in the Raf (Rapidly Accelerated Fibrosarcoma) kinase family; Raf kinases are serine/threonine kinases (STKs) that catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. They act as mitogen-activated protein kinase kinase kinases (MAP3Ks, MKKKs, MAPKKKs), which phosphorylate and activate MAPK kinases (MAPKKs or MKKs or MAP2Ks), which in turn phosphorylate and activate MAPKs during signaling cascades that are important in mediating cellular responses to extracellular signals. They function in the linear Ras-Raf-MEK-ERK pathway that regulates many cellular processes including cycle regulation, proliferation, differentiation, survival, and apoptosis. Aberrant expression or activation of components in this pathway are associated with tumor initiation, progression, and metastasis. Raf proteins contain a Ras binding domain, a zinc finger cysteine-rich domain (C1), and a catalytic kinase domain. Vertebrates have three Raf isoforms (A-, B-, and C-Raf) with different expression profiles, modes of regulation, and abilities to function in the ERK cascade, depending on cellular context and stimuli.

second protein kinase C conserved region 1 (C1 domain) found in the classical (or conventional) protein kinase C (cPKC) family; PKCs are classified into three groups (classical, atypical, and novel) depending on their mode of activation and the structural characteristics of their regulatory domain. cPKCs are potent kinases for histones, myelin basic protein, and protamine. They depend on calcium, DAG (1,2-diacylglycerol), and in most cases, phosphatidylserine (PS) for activation. There are four cPKC isoforms, named alpha, betaI, betaII, and gamma. PKC-alpha is expressed in many tissues and is associated with cell proliferation, apoptosis, and cell motility. It plays a role in the signaling of the growth factors PDGF, VEGF, EGF, and FGF. Abnormal levels of PKC-alpha have been detected in many transformed cell lines and several human tumors. In addition, PKC-alpha is required for HER2 dependent breast cancer invasion. The PKC beta isoforms (I and II), generated by alternative splicing of a single gene, are preferentially activated by hyperglycemia-induced DAG (1,2-diacylglycerol) in retinal tissues. This is implicated in diabetic microangiopathy such as ischemia, neovascularization, and abnormal vasodilator function. PKC-beta also plays an important role in VEGF signaling. In addition, glucose regulates proliferation in retinal endothelial cells via PKC-betaI. PKC-beta is also being explored as a therapeutic target in cancer. It contributes to tumor formation and is involved in the tumor host mechanisms of inflammation and angiogenesis. PKC-gamma is mainly expressed in neuronal tissues. It plays a role in protection from ischemia. Members of this family contain two copies of C1 domain. This model corresponds to the second one.

RAS p21 protein activator (GTPase activating protein) family pleckstrin homology (PH) domain; RASAL1, GAP1(m), GAP1(IP4BP), and CAPRI are all members of the GAP1 family of GTPase-activating proteins. They contain N-terminal SH2-SH3-SH2 domains, followed by two C2 domains, a PH domain, a RasGAP domain, and a BTK domain. With the notable exception of GAP1(m), they all possess an arginine finger-dependent GAP activity on the Ras-related protein Rap1. They act as a suppressor of RAS enhancing the weak intrinsic GTPase activity of RAS proteins resulting in the inactive GDP-bound form of RAS, allowing control of cellular proliferation and differentiation. PH domains share little sequence conservation, but all have a common fold, which is electrostatically polarized. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

protein kinase C conserved region 1 (C1 domain) found in the chimaerin family; Chimaerins are a family of phorbolester- and diacylglycerol-responsive GTPase activating proteins (GAPs) specific for the Rho-like GTPase Rac. Alpha1-chimerin (formerly known as N-chimerin) and alpha2-chimerin are alternatively spliced products of a single gene, as are beta1- and beta2-chimerin. Alpha1- and beta1-chimerin have a relatively short N-terminal region that does not encode any recognizable domains, whereas alpha2- and beta2-chimerin both include a functional SH2 domain that can bind to phosphotyrosine motifs within receptors. All the isoforms contain a GAP domain with specificity in vitro for Rac1 and a diacylglycerol (DAG)-binding C1 domain which allows them to translocate to membranes in response to DAG signaling and anchors them in close proximity to activated Rac. This model corresponds to the C1 domain.

In addition to the SAM domain, proteins of this group have ankyrin repeats and a ADP- ribosyltransferase (poly-(ADP-ribose) synthase) domain. Tankyrases can polymerize through their SAM domains forming homoligomers and these complexes are disrupted by autoribosylation. Tankyrases apparently act as master scaffolding proteins and thus may interact simultaneously with multiple proteins, in particular with TRF1, NuMA, IRAP and Grb14 (ankyrin repeats are involved in these interactions). Tankyrases participate in a variety of cell signaling pathways as effector molecules. Their functions are different depending on the intracellular location: at telomeres they play a role in the regulation of telomere length via control of telomerase access to telomeres, at centrosomes they promote spindle assembly/disassembly, in Golgi vesicles they participate in the regulation of vesicle trafficking and Golgi dynamics.

It is involved in axonal branching, synapse formation and dendritic morphogenesis, as well as in focal adhesion formation, cell motility and B-lymphocytes activation. ARHGEF2 acts as a guanine nucleotide exchange factor (GEF) that activates Rho-GTPases by promoting the exchange of GDP for GTP. It is thought to play a role in actin cytoskeleton reorganization in different tissues since its activation induces formation of actin stress fibers. AKAP-13 is a scaffold protein that plays an important role in assembling signaling complexes downstream of several types of G protein-coupled receptors. It activates RhoA in response to signaling via G protein-coupled receptors via its function as Rho guanine nucleotide exchange factor. It may also activate other Rho family members.

Myosin X Pleckstrin homology (PH) domain, repeat 2; MyoX, a MyTH-FERM myosin, is a molecular motor that has crucial functions in the transport and/or tethering of integrins in the actin-based extensions known as filopodia, microtubule binding, and in netrin-mediated axon guidance. It functions as a dimer. MyoX walks on bundles of actin, rather than single filaments, unlike the other unconventional myosins. MyoX is present in organisms ranging from humans to choanoflagellates, but not in Drosophila and Caenorhabditis elegans.MyoX consists of a N-terminal motor/head region, a neck made of 3 IQ motifs, and a tail consisting of a coiled-coil domain, a PEST region, 3 PH domains, a myosin tail homology 4 (MyTH4), and a FERM domain at its very C-terminus. The first PH domain in the MyoX tail is a split-PH domain, interupted by the second PH domain such that PH 1a and PH 1b flanks PH 2. The third PH domain (PH 3) follows the PH 1b domain. This cd contains the second PH repeat. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

With the notable exception of GAP1(m), they all possess an arginine finger-dependent GAP activity on the Ras-related protein Rap1. GAP1(IP4BP) contains two C2 domains, a PH domain, a RasGAP domain, and a BTK domain. Its C2 domains, like those of GAP1M, do not contain the C2 motif that is known to be required for calcium-dependent phospholipid binding. GAP1(IP4BP) is regulated by the binding of its PH domains to phophoinositides, PIP3 (phosphatidylinositol 3,4,5-trisphosphate) and PIP2 (phosphatidylinositol 4,5-bisphosphate). It suppresses RAS, enhancing the weak intrinsic GTPase activity of RAS proteins resulting in the inactive GDP-bound form of RAS, allowing control of cellular proliferation and differentiation. GAP1(IP4BP) binds tyrosine-protein kinase, HCK. Members here include humans, chickens, frogs, and fish. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner.

Switch-associated protein-70 Pleckstrin homology (PH) domain; SWAP-70 (also called Differentially expressed in FDCP 6/DEF-6 or IRF4-binding protein) functions in cellular signal transduction pathways (in conjunction with Rac), regulates cell motility through actin rearrangement, and contributes to the transformation and invasion activity of mouse embryo fibroblasts. Metazoan SWAP-70 is found in B lymphocytes, mast cells, and in a variety of organs. Metazoan SWAP-70 contains an N-terminal EF-hand motif, a centrally located PH domain, and a C-terminal coiled-coil domain. The PH domain of Metazoan SWAP-70 contains a phosphoinositide-binding site and a nuclear localization signal (NLS), which localize SWAP-70 to the plasma membrane and nucleus, respectively. The NLS is a sequence of four Lys residues located at the N-terminus of the C-terminal a-helix; this is a unique characteristic of the Metazoan SWAP-70 PH domain. The SWAP-70 PH domain binds PtdIns(3,4,5)P3 and PtdIns(4,5)P2 embedded in lipid bilayer vesicles. There are additional plant SWAP70 proteins, but these are not included in this hierarchy. Rice SWAP70 (OsSWAP70) exhibits GEF activity toward the its Rho GTPase, OsRac1, and regulates chitin-induced production of reactive oxygen species and defense gene expression in rice. Arabidopsis SWAP70 (AtSWAP70) plays a role in both PAMP- and effector-triggered immunity. Plant SWAP70 contains both DH and PH domains, but their arrangement is the reverse of that in typical DH-PH-type Rho GEFs, wherein the DH domain is flanked by a C-terminal PH domain. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

RASGRP1, also called calcium and DAG-regulated guanine nucleotide exchange factor II (CalDAG-GEFII) or Ras guanyl-releasing protein, activates the Erk/MAP kinase cascade and regulates T-cell/B-cell development, homeostasis and differentiation by coupling T-lymphocyte/B-lymphocyte antigen receptors to Ras. RASGRP1 also regulates NK cell cytotoxicity and ITAM-dependent cytokine production by activation of Ras-mediated ERK and JNK pathways. RASGRP2, also called calcium and DAG-regulated guanine nucleotide exchange factor I (CalDAG-GEFI), Cdc25-like protein (CDC25L), or F25B3.3 kinase-like protein, specifically activates Rap and may also activate other GTPases such as RRAS, RRAS2, NRAS, KRAS but not HRAS. RASGRP2 is involved in aggregation of platelets and adhesion of T-lymphocytes and neutrophils probably through inside-out integrin activation, as well as in the muscarinic acetylcholine receptor M1/CHRM1 signaling pathway. RASGRP3, also called calcium and DAG-regulated guanine nucleotide exchange factor III (CalDAG-GEFIII), or guanine nucleotide exchange factor for Rap1, is a guanine nucleotide-exchange factor activating H-Ras, R-Ras and Ras-associated protein-1/2. It functions as an important mediator of signaling downstream from receptor coupled phosphoinositide turnover in B and T cells. RASGRP4 may function in mast cell differentiation.

SAM domain of AIDA1AB-like proteins, repeat 1; SAM (sterile alpha motif) domain repeat 1 of AIDA1AB-like proteins is a protein-protein interaction domain. AIDA1AB-like proteins have two tandem SAM domains. They may form an intramolecular head-to-tail homodimer. One of two basic motifs of the nuclear localization signal (NLS) is located within helix 5 of SAM2 (motif HKRK). This signal plays a role in decoupling of SAM2 from SAM1, thus facilitating translocation of this type proteins into the nucleus. SAM1 domain has a potential phosphorylation site for CMGC group of serine/threonine kinases. SAM domains of the AIDA1-like subfamily can directly bind ubiquitin and participate in regulating the degradation of ubiquitinated EphA receptors, particularly EPH-A8 receptor. Additionally AIDA1AB-like proteins may participate in the regulation of nucleoplasmic coilin protein interactions. Pssm-ID: 188898 Cd Length: 67 Bit Score: 39.97 E-value: 3.76e-04

SAM domain of Polycomb group; SAM (sterile alpha motif) domain of Polycomb group is a protein-protein interaction domain. The Polycomb group includes transcriptional repressors which are involved in the regulation of some key regulatory genes during development in many organisms. They are best known for silencing Hox (Homeobox) genes. Polycomb proteins work together in large multimeric and chromatin-associated complexes. They organize chromatin of the target genes and maintain repressed states during many cell divisions. Polycomb proteins are classified based on their common function, but not on conserved domains and/or motifs; however many Polycomb proteins (members of PRC1 class complex) contain SAM domains which are more similar to each other inside of the Polycomb group than to SAM domains outside of it. Most information about structure and function of Polycomb SAM domains comes from studies of Ph (Polyhomeotic) and Scm (Sex comb on midleg) proteins. Polycomb SAM domains usually can be found at the C-terminus of the proteins. Some members of this group contain, in addition to the SAM domain, MTB repeats, Zn finger, and/or DUF3588 domains. Polycomb SAM domains can form homo- and/or heterooligomers through ML and EH surfaces. SAM/SAM oligomers apparently play a role in transcriptional repression through polymerization along the chromosome. Polycomb proteins are known to be highly expressed in some cells years before their cancer pathology; thus they are attractive markers for early cancer therapy.

Cryptosporidium-like Oxysterol binding protein related protein 2 Pleckstrin homology (PH) domain; There are 2 types of ORPs found in Cryptosporidium: CpORP1 and CpORP2. Cryptosporium differs from other apicomplexans like Plasmodium, Toxoplasma, and Eimeria which possess only a single long-type ORP consisting of an N-terminal PH domain followed by a C-terminal ligand binding (LB) domain. CpORP2 is like this, but CpORP1 differs and has a truncated N-terminus resulting in only having a LB domain present. The exact functions of these proteins are largely unknown though CpORP1 is thought to be involved in lipid transport across the parasitophorous vacuole membrane. Oxysterol binding proteins are a multigene family that is conserved in yeast, flies, worms, mammals and plants. In general OSBPs and ORPs have been found to be involved in the transport and metabolism of cholesterol and related lipids in eukaryotes. They all contain a C-terminal oxysterol binding domain, and most contain an N-terminal PH domain. OSBP PH domains bind to membrane phosphoinositides and thus likely play an important role in intracellular targeting. They are members of the oxysterol binding protein (OSBP) family which includes OSBP, OSBP-related proteins (ORP), Goodpasture antigen binding protein (GPBP), and Four phosphate adaptor protein 1 (FAPP1). They have a wide range of purported functions including sterol transport, cell cycle control, pollen development and vessicle transport from Golgi recognize both PI lipids and ARF proteins. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

Grb2-associated binding protein family Pleckstrin homology (PH) domain; Gab proteins are scaffolding adaptor proteins, which possess N-terminal PH domains and a C-terminus with proline-rich regions and multiple phosphorylation sites. Following activation of growth factor receptors, Gab proteins are tyrosine phosphorylated and activate PI3K, which generates 3-phosphoinositide lipids. By binding to these lipids via the PH domain, Gab proteins remain in proximity to the receptor, leading to further signaling. While not all Gab proteins depend on the PH domain for recruitment, it is required for Gab activity. There are 3 families: Gab1, Gab2, and Gab3. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized.

SH3 domain-binding protein 2 Pleckstrin homology (PH) domain; SH3BP2 (the gene that encodes the adaptor protein 3BP2), HD, ITU, IT10C3, and ADD1 are located near the Huntington's Disease Gene on Human Chromosome 4pl6.3. SH3BP2 lies in a region that is often missing in individuals with Wolf-Hirschhorn syndrome (WHS). Gain of function mutations in SH3BP2 causes enhanced B-cell antigen receptor (BCR)-mediated activation of nuclear factor of activated T cells (NFAT), resulting in a rare, genetic disorder called cherubism. This results in an increase in the signaling complex formation with Syk, phospholipase C-gamma2 (PLC-gamma2), and Vav1. It was recently discovered that Tankyrase regulates 3BP2 stability through ADP-ribosylation and ubiquitylation by the E3-ubiquitin ligase. Cherubism mutations uncouple 3BP2 from Tankyrase-mediated protein destruction, which results in its stabilization and subsequent hyperactivation of the Src, Syk, and Vav signaling pathways.

SAM domain of Arap3 protein was shown to interact with SAM domain of Ship2 phosphatidylinositol-trisphosphate phosphatase proteins. Such interaction apparently plays a role in inhibition of PI3K regulated pathways since Ship2 converts PI(3,4,5)P3 into PI(3,4)P2. Proteins of this subfamily participate in regulation of signaling and trafficking associated with a number of different receptors (including EGFR, TRAIL-R1/DR4, TRAIL-R2/DR5) in normal and cancer cells; they are involved in regulation of actin cytoskeleton remodeling, cell spreading and formation of lamellipodia.

52-141 | 3.65e-03 | ||||
Adaptor protein containing PH domain, PTB domain, and Leucine zipper motif Bin1/amphiphysin/Rvs167 (BAR)-Pleckstrin homology (PH) domain; APPL (also called DCC-interacting protein (DIP)-13alpha) interacts with oncoprotein serine/threonine kinase AKT2, tumor suppressor protein DCC (deleted in colorectal cancer), Rab5, GIPC (GAIP-interacting protein, C terminus), human follicle-stimulating hormone receptor (FSHR), and the adiponectin receptors AdipoR1 and AdipoR2. There are two isoforms of human APPL: APPL1 and APPL2, which share about 50% sequence identity. APPL has a BAR and a PH domain near its N terminus, and the two domains are thought to function as a unit (BAR-PH domain). C-terminal to this is a PTB domain. Lipid binding assays show that the BAR, PH, and PTB domains can bind phospholipids. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

protein kinase C conserved region 1 (C1 domain) found in unconventional myosin-IXa and similar proteins; Myosin-IXa, also called unconventional myosin-9a (Myo9a), is a single-headed, actin-dependent motor protein of the unconventional myosin IX class. It is expressed in several tissues and is enriched in the brain and testes. Myosin-IXa contains a Ras-associating (RA) domain, a motor domain, a protein kinase C conserved region 1 (C1), and a Rho GTPase activating domain (RhoGAP). Myosin-IXa binds the alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid receptor (AMPAR) GluA2 subunit, and plays a key role in controlling the molecular structure and function of hippocampal synapses. Moreover, Myosin-IXa functions in epithelial cell morphology and differentiation, such that its knockout mice develop hydrocephalus and kidney dysfunction. Myosin-IXa regulates collective epithelial cell migration by targeting RhoGAP activity to cell-cell junctions. Myosin-IXa negatively regulates Rho GTPase signaling, and functions as a regulator of kidney tubule function. This model corresponds to the C1 domain. The C1 domain is a cysteine-rich zinc binding domain that does not bind DNA nor possess structural similarity to conventional zinc finger domains; it contains two separate Zn(2+)-binding sites.

SAM domain of EPH-B6 subfamily of tyrosine kinase receptors; SAM (sterile alpha motif) domain of EPH-B6 subfamily of receptor tyrosine kinases is a C-terminal potential protein-protein interaction domain. This domain is located in the cytoplasmic region of EPH-B6 receptors and appears to mediate cell-cell initiated signal transduction. Receptors of this type are highly expressed in embryo and adult nervous system, in thymus and also in T-cells. They are involved in regulation of cell adhesion and migration. (EPH-B6 receptor is unusual; it fails to show catalytic activity due to alteration in kinase domain). EPH-B6 may be considered as a biomarker in some types of tumors; EPH-B6 activates MAP kinase signaling in lung adenocarcinoma, suppresses metastasis formation in non-small cell lung cancer, and slows invasiveness in some breast cancer cell lines.

SAM domain of DDHD2; SAM (sterile alpha motif) domain of DDHD2 group is a potential protein-protein interaction domain. DDHD2 proteins contain at least two domains:a SAM domain and a predicted metal-binding domain. Phospholipase A1 activity was demonstrated for the mammalian DDHD2 protein. Mutation of the putative catalytic serine resulted in elimination of activity. Unlike SEC23IP, DDHD2 proteins do not have an N-terminal proline-rich region and correspondingly they are not able to interact with Sec23p/Sec24p complex. Overexpression of DDHD2 is the cause of dispersion of ER/Golgi intermediate compartment and dispersion of tethering proteins located in the Golgi region, leading to aggregation in the endoplasmic reticulum.

Plant Oxysterol binding protein related protein Pleckstrin homology (PH) domain; Plant ORPs contain a N-terminal PH domain and a C-terminal OSBP-related domain. Not much is known about its specific function in plants to date. Members here include: Arabidopsis, spruce, and petunia. Oxysterol binding proteins are a multigene family that is conserved in yeast, flies, worms, mammals and plants. In general OSBPs and ORPs have been found to be involved in the transport and metabolism of cholesterol and related lipids in eukaryotes. They all contain a C-terminal oxysterol binding domain, and most contain an N-terminal PH domain. OSBP PH domains bind to membrane phosphoinositides and thus likely play an important role in intracellular targeting. They are members of the oxysterol binding protein (OSBP) family which includes OSBP, OSBP-related proteins (ORP), Goodpasture antigen binding protein (GPBP), and Four phosphate adaptor protein 1 (FAPP1). They have a wide range of purported functions including sterol transport, cell cycle control, pollen development and vessicle transport from Golgi recognize both PI lipids and ARF proteins. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner.

Boi family Pleckstrin homology domain; Yeast Boi proteins Boi1 and Boi2 are functionally redundant and important for cell growth with Boi mutants displaying defects in bud formation and in the maintenance of cell polarity.They appear to be linked to Rho-type GTPase, Cdc42 and Rho3. Boi1 and Boi2 display two-hybrid interactions with the GTP-bound ("active") form of Cdc42, while Rho3 can suppress of the lethality caused by deletion of Boi1 and Boi2. These findings suggest that Boi1 and Boi2 are targets of Cdc42 that promote cell growth in a manner that is regulated by Rho3. Boi proteins contain a N-terminal SH3 domain, followed by a SAM (sterile alpha motif) domain, a proline-rich region, which mediates binding to the second SH3 domain of Bem1, and C-terminal PH domain. The PH domain is essential for its function in cell growth and is important for localization to the bud, while the SH3 domain is needed for localization to the neck. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner.
