 706-1067 0e+00

Catalytic domain of Class IA Phosphoinositide 3-kinase beta; PI3Ks catalyze the transfer of the gamma-phosphoryl group from ATP to the 3-hydroxyl of the inositol ring of D-myo-phosphatidylinositol (PtdIns) or its derivatives. PI3Kbeta can be activated by G-protein-coupled receptors. Deletion of PI3Kbeta in mice results in early lethality at around day three of development. PI3Kbeta plays an important role in regulating sustained integrin activation and stable platelet agrregation, especially under conditions of high shear stress. PI3Ks can be divided into three main classes (I, II, and III), defined by their substrate specificity, regulation, and domain structure. Class I PI3Ks are the only enzymes capable of converting PtdIns(4,5)P2 to the critical second messenger PtdIns(3,4,5)P3. Class I enzymes are heterodimers and exist in multiple isoforms consisting of one catalytic subunit (out of four isoforms) and one of several regulatory subunits. They are further classified into class IA (alpha, beta and delta) and IB (gamma). Class IA enzymes contain an N-terminal p85 binding domain, a Ras binding domain, a lipid binding C2 domain, a PI3K homology domain of unknown function, and a C-terminal ATP-binding cataytic domain. They associate with a regulatory subunit of the p85 family and are activated by tyrosine kinase receptors. The PI3K catalytic domain family is part of a larger superfamily that includes the catalytic domains of other kinases such as the typical serine/threonine/tyrosine protein kinases (PKs), aminoglycoside phosphotransferase, choline kinase, and RIO kinases.

 532-702 3.88e-96

Phosphoinositide 3-kinase (PI3K) class I, accessory domain ; PIK domain is conserved in all PI3 and PI4-kinases. Its role is unclear but it has been suggested to be involved in substrate presentation. In general, PI3K class I prefer phosphoinositol (4,5)-bisphosphate as a substrate. Mammalian members interact with active Ras. They form heterodimers with adapter molecules linking them to different signaling pathways.

 324-501 2.10e-90

C2 domain present in class I beta and delta phosphatidylinositol 3-kinases (PI3Ks); PI3Ks (AKA phosphatidylinositol (PtdIns) 3-kinases) regulate cell processes such as cell growth, differentiation, proliferation, and motility. PI3Ks work on phosphorylation of phosphatidylinositol, phosphatidylinositide (4)P (PtdIns (4)P),2 or PtdIns(4,5)P2. Specifically they phosphorylate the D3 hydroxyl group of phosphoinositol lipids on the inositol ring. There are 3 classes of PI3Ks based on structure, regulation, and specificity. All classes contain a C2 domain, a PIK domain, and a kinase catalytic domain. The members here are class I, beta and delta isoforms of PI3Ks and contain both a Ras-binding domain and a p85-binding domain. Class II PI3Ks contain both of these as well as a PX domain, and a C-terminal C2 domain containing a nuclear localization signal. C2 domains fold into an 8-standed beta-sandwich that can adopt 2 structural arrangements: Type I and Type II, distinguished by a circular permutation involving their N- and C-terminal beta strands. Many C2 domains are Ca2+-dependent membrane-targeting modules that bind a wide variety of substances including bind phospholipids, inositol polyphosphates, and intracellular proteins. Most C2 domain proteins are either signal transduction enzymes that contain a single C2 domain, such as protein kinase C, or membrane trafficking proteins which contain at least two C2 domains, such as synaptotagmin 1. However, there are a few exceptions to this including RIM isoforms and some splice variants of piccolo/aczonin and intersectin which only have a single C2 domain. C2 domains with a calcium binding region have negatively charged residues, primarily aspartates, that serve as ligands for calcium ions. Members have a type-I topology.

C2 domains with a calcium binding region have negatively charged residues, primarily aspartates, that serve as ligands for calcium ions. Members have a type-I topology.

 802-1019 2.03e-80

Phosphoinositide 3-kinase, catalytic domain; Phosphoinositide 3-kinase isoforms participate in a variety of processes, including cell motility, the Ras pathway, vesicle trafficking and secretion, and apoptosis. These homologues may be either lipid kinases and/or protein kinases: the former phosphorylate the 3-position in the inositol ring of inositol phospholipids. The ataxia telangiectesia-mutated gene produced, the targets of rapamycin (TOR) and the DNA-dependent kinase have not been found to possess lipid kinase activity. Some of this family possess PI-4 kinase activities.

 706-1067 0e+00

Catalytic domain of Class IA Phosphoinositide 3-kinase beta; PI3Ks catalyze the transfer of the gamma-phosphoryl group from ATP to the 3-hydroxyl of the inositol ring of D-myo-phosphatidylinositol (PtdIns) or its derivatives. PI3Kbeta can be activated by G-protein-coupled receptors. Deletion of PI3Kbeta in mice results in early lethality at around day three of development. PI3Kbeta plays an important role in regulating sustained integrin activation and stable platelet agrregation, especially under conditions of high shear stress. PI3Ks can be divided into three main classes (I, II, and III), defined by their substrate specificity, regulation, and domain structure. Class I PI3Ks are the only enzymes capable of converting PtdIns(4,5)P2 to the critical second messenger PtdIns(3,4,5)P3. Class I enzymes are heterodimers and exist in multiple isoforms consisting of one catalytic subunit (out of four isoforms) and one of several regulatory subunits. They are further classified into class IA (alpha, beta and delta) and IB (gamma). Class IA enzymes contain an N-terminal p85 binding domain, a Ras binding domain, a lipid binding C2 domain, a PI3K homology domain of unknown function, and a C-terminal ATP-binding cataytic domain. They associate with a regulatory subunit of the p85 family and are activated by tyrosine kinase receptors. The PI3K catalytic domain family is part of a larger superfamily that includes the catalytic domains of other kinases such as the typical serine/threonine/tyrosine protein kinases (PKs), aminoglycoside phosphotransferase, choline kinase, and RIO kinases.

Catalytic domain of Class IA Phosphoinositide 3-kinase delta; PI3Ks catalyze the transfer of the gamma-phosphoryl group from ATP to the 3-hydroxyl of the inositol ring of D-myo-phosphatidylinositol (PtdIns) or its derivatives. PI3Kdelta is mainly expressed in immune cells and plays an important role in cellular and humoral immunity. It plays a major role in antigen receptor signaling in B-cells, T-cells, and mast cells. It regulates the differentiation of peripheral helper T-cells and controls the development and function of regulatory T-cells. PI3Ks can be divided into three main classes (I, II, and III), defined by their substrate specificity, regulation, and domain structure. Class I PI3Ks are the only enzymes capable of converting PtdIns(4,5)P2 to the critical second messenger PtdIns(3,4,5)P3.

Catalytic domain of Class II Phosphoinositide 3-kinase; PI3Ks catalyze the transfer of the gamma-phosphoryl group from ATP to the 3-hydroxyl of the inositol ring of D-myo-phosphatidylinositol (PtdIns) or its derivatives. PI3Ks play an important role in a variety of fundamental cellular processes, including cell motility, the Ras pathway, vesicle trafficking and secretion, immune cell activation and apoptosis. They can be divided into three main classes (I, II, and III), defined by their substrate specificity, regulation, and domain structure. Class II PI3Ks preferentially use PtdIns as a substrate to produce PtdIns(3)P, but can also phosphorylate PtdIns(4)P. They function as monomers and do not associate with any regulatory subunits. Class II enzymes contain an N-terminal Ras binding domain, a lipid binding C2 domain, a PI3K homology domain of unknown function, an ATP-binding cataytic domain, a Phox homology (PX) domain, and a second C2 domain at the C-terminus. They are activated by a variety of stimuli including chemokines, cytokines, lysophosphatidic acid (LPA), insulin, and tyrosine kinase receptors. The PI3K catalytic domain family is part of a larger superfamily that includes the catalytic domains of other kinases such as the typical serine/threonine/tyrosine protein kinases (PKs), aminoglycoside phosphotransferase, choline kinase, and RIO kinases.

Catalytic domain of Class IB Phosphoinositide 3-kinase gamma; PI3Ks catalyze the transfer of the gamma-phosphoryl group from ATP to the 3-hydroxyl of the inositol ring of D-myo-phosphatidylinositol (PtdIns) or its derivatives. PI3Kgamma signaling controls diverse immune and vascular functions including cell recruitment, mast cell activation, platelet aggregation, and smooth muscle contractility. It associates with one of two regulatory subunits, p101 and p84, and is activated by G-protein-coupled receptors (GPCRs) by direct binding to their betagamma subunits. It contains an N-terminal Ras binding domain, a lipid binding C2 domain, a PI3K homology domain of unknown function, and a C-terminal ATP-binding cataytic domain. PI3Ks can be divided into three main classes (I, II, and III), defined by their substrate specificity, regulation, and domain structure. Class I PI3Ks are the only enzymes capable of converting PtdIns(4,5)P2 to the critical second messenger PtdIns(3,4,5)P3. Class I enzymes are heterodimers and exist in multiple isoforms consisting of one catalytic subunit (out of four isoforms) and one of several regulatory subunits. They are further classified into class IA (alpha, beta and delta) and IB (gamma). The PI3K catalytic domain family is part of a larger superfamily that includes the catalytic domains of other kinases such as the typical serine/threonine/tyrosine protein kinases (PKs), aminoglycoside phosphotransferase, choline kinase, and RIO kinases.

Catalytic domain of Class IA Phosphoinositide 3-kinase alpha; PI3Ks catalyze the transfer of the gamma-phosphoryl group from ATP to the 3-hydroxyl of the inositol ring of D-myo-phosphatidylinositol (PtdIns) or its derivatives. PI3Kalpha plays an important role in insulin signaling. It also mediates physiologic heart growth and provides protection from stress. Activating mutations of PI3Kalpha is associated with diverse forms of cancer at high frequency. PI3Ks can be divided into three main classes (I, II, and III), defined by their substrate specificity, regulation, and domain structure. Class I PI3Ks are the only enzymes capable of converting PtdIns(4,5)P2 to the critical second messenger PtdIns(3,4,5)P3. Class I enzymes are heterodimers and exist in multiple isoforms consisting of one catalytic subunit (out of four isoforms) and one of several regulatory subunits. They are further classified into class IA (alpha, beta and delta) and IB (gamma). Class IA enzymes contain an N-terminal p85 binding domain, a Ras binding domain, a lipid binding C2 domain, a PI3K homology domain of unknown function, and a C-terminal ATP-binding cataytic domain. They associate with a regulatory subunit of the p85 family and are activated by tyrosine kinase receptors. The PI3K catalytic domain family is part of a larger superfamily that includes the catalytic domains of other kinases such as the typical serine/threonine/tyrosine protein kinases (PKs), aminoglycoside phosphotransferase, choline kinase, and RIO kinases.

 532-702 3.88e-96

Phosphoinositide 3-kinase (PI3K) class I, accessory domain ; PIK domain is conserved in all PI3 and PI4-kinases. Its role is unclear but it has been suggested to be involved in substrate presentation. In general, PI3K class I prefer phosphoinositol (4,5)-bisphosphate as a substrate. Mammalian members interact with active Ras. They form heterodimers with adapter molecules linking them to different signaling pathways.

 324-501 2.10e-90

C2 domain present in class I beta and delta phosphatidylinositol 3-kinases (PI3Ks); PI3Ks (AKA phosphatidylinositol (PtdIns) 3-kinases) regulate cell processes such as cell growth, differentiation, proliferation, and motility. PI3Ks work on phosphorylation of phosphatidylinositol, phosphatidylinositide (4)P (PtdIns (4)P),2 or PtdIns(4,5)P2. Specifically they phosphorylate the D3 hydroxyl group of phosphoinositol lipids on the inositol ring. There are 3 classes of PI3Ks based on structure, regulation, and specificity. All classes contain a C2 domain, a PIK domain, and a kinase catalytic domain. The members here are class I, beta and delta isoforms of PI3Ks and contain both a Ras-binding domain and a p85-binding domain. Class II PI3Ks contain both of these as well as a PX domain, and a C-terminal C2 domain containing a nuclear localization signal. C2 domains fold into an 8-standed beta-sandwich that can adopt 2 structural arrangements: Type I and Type II, distinguished by a circular permutation involving their N- and C-terminal beta strands. Many C2 domains are Ca2+-dependent membrane-targeting modules that bind a wide variety of substances including bind phospholipids, inositol polyphosphates, and intracellular proteins. Most C2 domain proteins are either signal transduction enzymes that contain a single C2 domain, such as protein kinase C, or membrane trafficking proteins which contain at least two C2 domains, such as synaptotagmin 1. However, there are a few exceptions to this including RIM isoforms and some splice variants of piccolo/aczonin and intersectin which only have a single C2 domain. C2 domains with a calcium binding region have negatively charged residues, primarily aspartates, that serve as ligands for calcium ions. Members have a type-I topology.

Catalytic domain of Class II Phosphoinositide 3-kinase alpha; PI3Ks catalyze the transfer of the gamma-phosphoryl group from ATP to the 3-hydroxyl of the inositol ring of D-myo-phosphatidylinositol (PtdIns) or its derivatives. The class II alpha isoform, PI3K-C2alpha, plays key roles in clathrin assembly and clathrin-mediated membrane trafficking, insulin signaling, vascular smooth muscle contraction, and the priming of neurosecretory granule exocytosis. PI3Ks play an important role in a variety of fundamental cellular processes, including cell motility, the Ras pathway, vesicle trafficking and secretion, immune cell activation and apoptosis. They can be divided into three main classes (I, II, and III), defined by their substrate specificity, regulation, and domain structure. Class II PI3Ks preferentially use PtdIns as a substrate to produce PtdIns(3)P, but can also phosphorylate PtdIns(4)P. They function as monomers and do not associate with any regulatory subunits. Class II enzymes contain an N-terminal Ras binding domain, a lipid binding C2 domain, a PI3K homology domain of unknown function, an ATP-binding cataytic domain, a Phox homology (PX) domain, and a second C2 domain at the C-terminus. The PI3K catalytic domain family is part of a larger superfamily that includes the catalytic domains of other kinases such as the typical serine/threonine/tyrosine protein kinases (PKs), aminoglycoside phosphotransferase, choline kinase, and RIO kinases.

Phosphoinositide 3-kinase, catalytic domain; Phosphoinositide 3-kinase isoforms participate in a variety of processes, including cell motility, the Ras pathway, vesicle trafficking and secretion, and apoptosis. These homologues may be either lipid kinases and/or protein kinases: the former phosphorylate the 3-position in the inositol ring of inositol phospholipids. The ataxia telangiectesia-mutated gene produced, the targets of rapamycin (TOR) and the DNA-dependent kinase have not been found to possess lipid kinase activity. Some of this family possess PI-4 kinase activities.

Catalytic domain of Class II Phosphoinositide 3-kinase gamma; PI3Ks catalyze the transfer of the gamma-phosphoryl group from ATP to the 3-hydroxyl of the inositol ring of D-myo-phosphatidylinositol (PtdIns) or its derivatives. The class II gamma isoform, PI3K-C2gamma, is expressed in the liver, breast, and prostate. PI3Ks play an important role in a variety of fundamental cellular processes, including cell motility, the Ras pathway, vesicle trafficking and secretion, immune cell activation and apoptosis. They can be divided into three main classes (I, II, and III), defined by their substrate specificity, regulation, and domain structure. Class II PI3Ks preferentially use PtdIns as a substrate to produce PtdIns(3)P, but can also phosphorylate PtdIns(4)P. They function as monomers and do not associate with any regulatory subunits. Class II enzymes contain an N-terminal Ras binding domain, a lipid binding C2 domain, a PI3K homology domain of unknown function, an ATP-binding cataytic domain, a Phox homology (PX) domain, and a second C2 domain at the C-terminus. It's biological function remains unknown. The PI3K catalytic domain family is part of a larger superfamily that includes the catalytic domains of other kinases such as the typical serine/threonine/tyrosine protein kinases (PKs), aminoglycoside phosphotransferase, choline kinase, and RIO kinases.

Catalytic domain of Class III Phosphoinositide 3-kinase; PI3Ks catalyze the transfer of the gamma-phosphoryl group from ATP to the 3-hydroxyl of the inositol ring of D-myo-phosphatidylinositol (PtdIns) or its derivatives. Class III PI3Ks, also called Vps34 (vacuolar protein sorting 34), contain an N-terminal lipid binding C2 domain, a PI3K homology domain of unknown function, and a C-terminal ATP-binding cataytic domain. They phosphorylate only the substrate PtdIns. They interact with a regulatory subunit, Vps15, to form a membrane-associated complex. Class III PI3Ks are involved in protein and vesicular trafficking and sorting, autophagy, trimeric G-protein signaling, and phagocytosis. PI3Ks play an important role in a variety of fundamental cellular processes, including cell motility, the Ras pathway, vesicle trafficking and secretion, immune cell activation and apoptosis. They can be divided into three main classes (I, II, and III), defined by their substrate specificity, regulation, and domain structure.

Catalytic domain of Class II Phosphoinositide 3-kinase beta; PI3Ks catalyze the transfer of the gamma-phosphoryl group from ATP to the 3-hydroxyl of the inositol ring of D-myo-phosphatidylinositol (PtdIns) or its derivatives. The class II beta isoform, PI3K-C2beta, contributes to the migration and survival of cancer cells. It regulates Rac activity and impacts membrane ruffling, cell motility, and cadherin-mediated cell-cell adhesion. PI3Ks play an important role in a variety of fundamental cellular processes, including cell motility, the Ras pathway, vesicle trafficking and secretion, immune cell activation and apoptosis.

Phosphoinositide 3-kinase family, accessory domain (PIK domain); PIK domain is conserved in PI3 and PI4-kinases. Its role is unclear, but it has been suggested to be involved in substrate presentation. Phosphoinositide 3-kinases play an important role in a variety of fundamental cellular processes and can be divided into three main classes, defined by their substrate specificity and domain architecture.

 767-1056 7.84e-50

Catalytic domain of Type III Phosphoinositide 4-kinase alpha; PI4Ks catalyze the transfer of the gamma-phosphoryl group from ATP to the 4-hydroxyl of the inositol ring of D-myo-phosphatidylinositol (PtdIns) to generate PtdIns(4)P, the major precursor in the synthesis of other phosphoinositides including PtdIns(4,5)P2, PtdIns(3,4)P2, and PtdIns(3,4,5)P3. Two isoforms of type III PI4K, alpha and beta, exist in most eukaryotes. PI4KIIIalpha is a 220 kDa protein found in the plasma membrane and the endoplasmic reticulum (ER). The role of PI4KIIIalpha in the ER remains unclear. In the plasma membrane, it provides PtdIns(4)P, which is then converted by PI5Ks to PtdIns(4,5)P2, an important signaling molecule. Vertebrate PI4KIIIalpha is also part of a signaling complex associated with P2X7 ion channels. The yeast homolog, Stt4p, is also important in regulating the conversion of phosphatidylserine to phosphatidylethanolamine at the ER and Golgi interface. Mammalian PI4KIIIalpha is highly expressed in the nervous system. The PI4K catalytic domain family is part of a larger superfamily that includes the catalytic domains of other kinases such as the typical serine/threonine/tyrosine protein kinases (PKs), aminoglycoside phosphotransferase, choline kinase, and RIO kinases.

There are two types of PI4Ks, types II and III. Type II PI4Ks lack the characteristic catalytic kinase domain present in PI3Ks and type III PI4Ks, and are excluded from this family. Two isoforms of type III PI4K, alpha and beta, exist in most eukaryotes. The PI4K catalytic domain family is part of a larger superfamily that includes the catalytic domains of other kinases such as the typical serine/threonine/tyrosine protein kinases (PKs), aminoglycoside phosphotransferase, choline kinase, and RIO kinases.

Two isoforms of type III PI4K, alpha and beta, exist in most eukaryotes. PI4KIIIbeta (also called Pik1p in yeast) is a 110 kDa protein that is localized to the Golgi and the nucleus. It is required for maintaining the structural integrity of the Golgi complex (GC), and is a key regulator of protein transport from the GC to the plasma membrane. PI4KIIIbeta also functions in the genesis, transport, and exocytosis of synaptic vesicles. The Drosophila PI4KIIIbeta is essential for cytokinesis during spermatogenesis. The PI4K catalytic domain family is part of a larger superfamily that includes the catalytic domains of other kinases such as the typical serine/threonine/tyrosine protein kinases (PKs), aminoglycoside phosphotransferase, choline kinase, and RIO kinases.

Catalytic domain of Phosphoinositide 3-kinase and similar proteins; Members of the family include PI3K, phosphoinositide 4-kinase (PI4K), PI3K-related protein kinases (PIKKs), and TRansformation/tRanscription domain-Associated Protein (TRAPP). PI3Ks catalyze the transfer of the gamma-phosphoryl group from ATP to the 3-hydroxyl of the inositol ring of D-myo-phosphatidylinositol (PtdIns) or its derivatives, while PI4K catalyze the phosphorylation of the 4-hydroxyl of PtdIns. PIKKs are protein kinases that catalyze the phosphorylation of serine/threonine residues, especially those that are followed by a glutamine. PI3Ks play an important role in a variety of fundamental cellular processes, including cell motility, the Ras pathway, vesicle trafficking and secretion, immune cell activation and apoptosis. PI4Ks produce PtdIns(4)P, the major precursor to important signaling phosphoinositides. PIKKs have diverse functions including cell-cycle checkpoints, genome surveillance, mRNA surveillance, and translation control. The PI3K-like catalytic domain family is part of a larger superfamily that includes the catalytic domains of other kinases such as the typical serine/threonine/tyrosine protein kinases (PKs), aminoglycoside phosphotransferase, choline kinase, and RIO kinases.

C2 domain present in phosphatidylinositol 3-kinases (PI3Ks); C2 domain present in all classes of PI3Ks. PI3Ks (AKA phosphatidylinositol (PtdIns) 3-kinases) regulate cell processes such as cell growth, differentiation, proliferation, and motility. PI3Ks work on phosphorylation of phosphatidylinositol, phosphatidylinositide (4)P (PtdIns (4)P),2 or PtdIns(4,5)P2. Specifically they phosphorylate the D3 hydroxyl group of phosphoinositol lipids on the inositol ring. There are 3 classes of PI3Ks based on structure, regulation, and specificity. All classes contain a C2 domain, a PIK domain, and a kinase catalytic domain. In addition some PI3Ks contain a Ras-binding domain and/or a p85-binding domain. Class II PI3Ks contain both of these as well as a PX domain, and a C-terminal C2 domain containing a nuclear localization signal. C2 domains fold into an 8-standed beta-sandwich that can adopt 2 structural arrangements: Type I and Type II, distinguished by a circular permutation involving their N- and C-terminal beta strands. Many C2 domains are Ca2+-dependent membrane-targeting modules that bind a wide variety of substances including bind phospholipids, inositol polyphosphates, and intracellular proteins. Most C2 domain proteins are either signal transduction enzymes that contain a single C2 domain, such as protein kinase C, or membrane trafficking proteins which contain at least two C2 domains, such as synaptotagmin 1. However, there are a few exceptions to this including RIM isoforms and some splice variants of piccolo/aczonin and intersectin which only have a single C2 domain. C2 domains with a calcium binding region have negatively charged residues, primarily aspartates, that serve as ligands for calcium ions. This cd contains members with the first C2 repeat, C2A, and a type-I topology, as well as some with a single C2 repeat.

Phosphoinositide 3-kinase (PI3K) class III, accessory domain (PIK domain); PIK domain is conserved in all PI3 and PI4-kinases. Its role is unclear but it has been suggested to be involved in substrate presentation. In general, PI3Ks class III phosphorylate phosphoinositol (PtdIns) only. The prototypical PI3K class III, yeast Vps34, is involved in trafficking proteins from Golgi to the vacuole.

 803-1008 8.48e-27

Catalytic domain of Phosphoinositide 3-kinase-related protein kinases; PIKK subfamily members include ATM (Ataxia telangiectasia mutated), ATR (Ataxia telangiectasia and Rad3-related), TOR (Target of rapamycin), SMG-1 (Suppressor of morphogenetic effect on genitalia-1), and DNA-PK (DNA-dependent protein kinase). PIKKs have intrinsic serine/threonine kinase activity and are distinguished from other PKs by their unique catalytic domain, similar to that of lipid PI3K, and their large molecular weight (240-470 kDa). They show strong preference for phosphorylating serine/threonine residues followed by a glutamine and are also referred to as (S/T)-Q-directed kinases. They all contain a FATC (FRAP, ATM and TRRAP, C-terminal) domain. PIKKs have diverse functions including cell-cycle checkpoints, genome surveillance, mRNA surveillance, and translation control. The PIKK catalytic domain subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as the typical serine/threonine/tyrosine protein kinases (PKs), aminoglycoside phosphotransferase, choline kinase, and RIO kinases.

C2 domain present in class I alpha phosphatidylinositol 3-kinases (PI3Ks); PI3Ks (AKA phosphatidylinositol (PtdIns) 3-kinases) regulate cell processes such as cell growth, differentiation, proliferation, and motility. PI3Ks work on phosphorylation of phosphatidylinositol, phosphatidylinositide (4)P (PtdIns (4)P),2 or PtdIns(4,5)P2. Specifically they phosphorylate the D3 hydroxyl group of phosphoinositol lipids on the inositol ring. There are 3 classes of PI3Ks based on structure, regulation, and specificity. All classes contain a C2 domain, a PIK domain, and a kinase catalytic domain. The members here are class I, alpha isoform PI3Ks and contain both a Ras-binding domain and a p85-binding domain. Class II PI3Ks contain both of these as well as a PX domain, and a C-terminal C2 domain containing a nuclear localization signal. C2 domains fold into an 8-standed beta-sandwich that can adopt 2 structural arrangements: Type I and Type II, distinguished by a circular permutation involving their N- and C-terminal beta strands. Many C2 domains are Ca2+-dependent membrane-targeting modules that bind a wide variety of substances including bind phospholipids, inositol polyphosphates, and intracellular proteins. Most C2 domain proteins are either signal transduction enzymes that contain a single C2 domain, such as protein kinase C, or membrane trafficking proteins which contain at least two C2 domains, such as synaptotagmin 1. However, there are a few exceptions to this including RIM isoforms and some splice variants of piccolo/aczonin and intersectin which only have a single C2 domain. C2 domains with a calcium binding region have negatively charged residues, primarily aspartates, that serve as ligands for calcium ions. Members have a type-I topology.

Catalytic domain of Ataxia Telangiectasia Mutated; ATM is critical in the response to DNA double strand breaks (DSBs) caused by radiation. It is activated at the site of a DSB and phosphorylates key substrates that trigger pathways that regulate DNA repair and cell cycle checkpoints at the G1/S, S phase, and G2/M transition. Patients with the human genetic disorder Ataxia telangiectasia (A-T), caused by truncating mutations in ATM, show genome instability, increased cancer risk, immunodeficiency, compromised mobility, and neurodegeneration. A-T displays clinical heterogeneity, which is correlated to the degree of retained ATM activity. ATM contains a FAT (FRAP, ATM and TRRAP) domain, a catalytic domain, and a FATC domain at the C-terminus. It is a member of the phosphoinositide 3-kinase-related protein kinase (PIKK) subfamily. PIKKs have intrinsic serine/threonine kinase activity and are distinguished from other PKs by their unique catalytic domain, similar to that of lipid PI3K, and their large molecular weight (240-470 kDa). The ATM catalytic domain subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as the typical serine/threonine/tyrosine protein kinases (PKs), aminoglycoside phosphotransferase, choline kinase, and RIO kinases.

Catalytic domain of DNA-dependent protein kinase; DNA-PK is comprised of a regulatory subunit, containing the Ku70/80 subunit, and a catalytic subunit, which contains a NUC194 domain of unknown function, a FAT (FRAP, ATM and TRRAP) domain, a catalytic domain, and a FATC domain at the C-terminus. It is part of a multi-component system involved in non-homologous end joining (NHEJ), a process of repairing double strand breaks (DSBs) by joining together two free DNA ends of little homology. DNA-PK functions as a molecular sensor for DNA damage that enhances the signal via phosphorylation of downstream targets. It may also act as a protein scaffold that aids the localization of DNA repair proteins to the site of DNA damage. DNA-PK also plays a role in the maintenance of telomeric stability and the prevention of chromosomal end fusion. DNA-PK is a member of the phosphoinositide 3-kinase-related protein kinase (PIKK) subfamily. PIKKs have intrinsic serine/threonine kinase activity and are distinguished from other PKs by their unique catalytic domain, similar to that of lipid PI3K, and their large molecular weight (240-470 kDa).

Catalytic domain of Ataxia telangiectasia and Rad3-related proteins; ATR is also referred to as Mei-41 (Drosophila), Esr1/Mec1p (Saccharomyces cerevisiae), Rad3 (Schizosaccharomyces pombe), and FRAP-related protein (human). ATR contains a UME domain of unknown function, a FAT (FRAP, ATM and TRRAP) domain, a catalytic domain, and a FATC domain at the C-terminus. Together with its downstream effector kinase, Chk1, ATR plays a central role in regulating the replication checkpoint. ATR stabilizes replication forks by promoting the association of DNA polymerases with the fork. Preventing fork collapse is essential in preserving genomic integrity. ATR also plays a role in normal cell growth and in response to DNA damage. ATR is a member of the phosphoinositide 3-kinase-related protein kinase (PIKK) subfamily. PIKKs have intrinsic serine/threonine kinase activity and are distinguished from other PKs by their unique catalytic domain, similar to that of lipid PI3K, and their large molecular weight (240-470 kDa). The ATR catalytic domain subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as the typical serine/threonine/tyrosine protein kinases (PKs), aminoglycoside phosphotransferase, choline kinase, and RIO kinases.

Catalytic domain of Target of Rapamycin; TOR contains a rapamycin binding domain, a catalytic domain, and a FATC (FRAP, ATM and TRRAP, C-terminal) domain at the C-terminus. It is also called FRAP (FK506 binding protein 12-rapamycin associated protein). TOR is a central component of the eukaryotic growth regulatory network. It controls the expression of many genes transcribed by all three RNA polymerases. It associates with other proteins to form two distinct complexes, TORC1 and TORC2. TORC1 is involved in diverse growth-related functions including protein synthesis, nutrient use and transport, autophagy and stress responses. TORC2 is involved in organizing cytoskeletal structures. TOR is a member of the phosphoinositide 3-kinase-related protein kinase (PIKK) subfamily. PIKKs have intrinsic serine/threonine kinase activity and are distinguished from other PKs by their unique catalytic domain, similar to that of lipid PI3K, and their large molecular weight (240-470 kDa). The TOR catalytic domain subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as the typical serine/threonine/tyrosine protein kinases (PKs), aminoglycoside phosphotransferase, choline kinase, and RIO kinases.

 352-497 6.27e-17

C2 domain first repeat present in class II phosphatidylinositol 3-kinases (PI3Ks); There are 3 classes of PI3Ks based on structure, regulation, and specificity. All classes contain a N-terminal C2 domain, a PIK domain, and a kinase catalytic domain. Unlike class I and class III, class II PI3Ks have additionally a PX domain and a C-terminal C2 domain containing a nuclear localization signal both of which bind phospholipids though in a slightly different fashion. Class II PIK3s act downstream of receptors for growth factors, integrins, and chemokines. PI3Ks (AKA phosphatidylinositol (PtdIns) 3-kinases) regulate cell processes such as cell growth, differentiation, proliferation, and motility. PI3Ks work on phosphorylation of phosphatidylinositol, phosphatidylinositide (4)P (PtdIns (4)P),2 or PtdIns(4,5)P2. Specifically they phosphorylate the D3 hydroxyl group of phosphoinositol lipids on the inositol ring. C2 domains fold into an 8-standed beta-sandwich that can adopt 2 structural arrangements: Type I and Type II, distinguished by a circular permutation involving their N- and C-terminal beta strands. Many C2 domains are Ca2+-dependent membrane-targeting modules that bind a wide variety of substances including bind phospholipids, inositol polyphosphates, and intracellular proteins. Most C2 domain proteins are either signal transduction enzymes that contain a single C2 domain, such as protein kinase C, or membrane trafficking proteins which contain at least two C2 domains, such as synaptotagmin 1. However, there are a few exceptions to this including RIM isoforms and some splice variants of piccolo/aczonin and intersectin which only have a single C2 domain. C2 domains with a calcium binding region have negatively charged residues, primarily aspartates, that serve as ligands for calcium ions. This cd contains the first C2 repeat, C2A, and has a type-I topology.

 896-1004 6.88e-14

Catalytic domain of Suppressor of Morphogenetic effect on Genitalia-1; SMG-1 plays a critical role in the mRNA surveillance mechanism known as non-sense mediated mRNA decay (NMD). NMD protects the cells from the accumulation of aberrant mRNAs with premature termination codons (PTCs) generated by genome mutations and by errors during transcription and splicing. SMG-1 phosphorylates Upf1, another central component of NMD, at the C-terminus upon recognition of PTCs. The phosphorylation/dephosphorylation cycle of Upf1 is essential for promoting NMD. In addition to its catalytic domain, SMG-1 contains a FATC (FRAP, ATM and TRRAP, C-terminal) domain at the C-terminus. SMG-1 is a member of the phosphoinositide 3-kinase-related protein kinase (PIKK) subfamily. PIKKs have intrinsic serine/threonine kinase activity and are distinguished from other PKs by their unique catalytic domain, similar to that of lipid PI3K, and their large molecular weight (240-470 kDa). The SMG-1 catalytic domain subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as the typical serine/threonine/tyrosine protein kinases (PKs), aminoglycoside phosphotransferase, choline kinase, and RIO kinases.

PI3Ks work on phosphorylation of phosphatidylinositol, phosphatidylinositide (4)P (PtdIns (4)P),2 or PtdIns(4,5)P2. Specifically they phosphorylate the D3 hydroxyl group of phosphoinositol lipids on the inositol ring. There are 3 classes of PI3Ks based on structure, regulation, and specificity. All classes contain a C2 domain, a PIK domain, and a kinase catalytic domain. The members here are class I, gamma isoform PI3Ks and contain both a Ras-binding domain and a p85-binding domain. Class II PI3Ks contain both of these as well as a PX domain, and a C-terminal C2 domain containing a nuclear localization signal. C2 domains fold into an 8-standed beta-sandwich that can adopt 2 structural arrangements: Type I and Type II, distinguished by a circular permutation involving their N- and C-terminal beta strands. Many C2 domains are Ca2+-dependent membrane-targeting modules that bind a wide variety of substances including bind phospholipids, inositol polyphosphates, and intracellular proteins. Most C2 domain proteins are either signal transduction enzymes that contain a single C2 domain, such as protein kinase C, or membrane trafficking proteins which contain at least two C2 domains, such as synaptotagmin 1. However, there are a few exceptions to this including RIM isoforms and some splice variants of piccolo/aczonin and intersectin which only have a single C2 domain. C2 domains with a calcium binding region have negatively charged residues, primarily aspartates, that serve as ligands for calcium ions. Members have a type-I topology.

Catalytic domain of the Protein Kinase superfamily; The PK superfamily contains the large family of typical PKs that includes serine/threonine kinases (STKs), protein tyrosine kinases (PTKs), and dual-specificity PKs that phosphorylate both serine/threonine and tyrosine residues of target proteins, as well as pseudokinases that lack crucial residues for catalytic activity and/or ATP binding. It also includes phosphoinositide 3-kinases (PI3Ks), aminoglycoside 3'-phosphotransferases (APHs), choline kinase (ChoK), Actin-Fragmin Kinase (AFK), and the atypical RIO and Abc1p-like protein kinases. These proteins catalyze the transfer of the gamma-phosphoryl group from ATP to their target substrates; these include serine/threonine/tyrosine residues in proteins for typical or atypical PKs, the 3-hydroxyl of the inositol ring of D-myo-phosphatidylinositol (PtdIns) or its derivatives for PI3Ks, the 4-hydroxyl of PtdIns for PI4Ks, and other small molecule substrates for APH/ChoK and similar proteins such as aminoglycosides, macrolides, choline, ethanolamine, and homoserine.

 877-961 1.33e-03

Pseudokinase domain of TRansformation/tRanscription domain-Associated Protein; TRRAP belongs to the the phosphoinositide 3-kinase-related protein kinase (PIKK) subfamily. It contains a FATC (FRAP, ATM and TRRAP, C-terminal) domain and has a large molecular weight. Unlike most PIKK proteins, however, it contains an inactive PI3K-like pseudokinase domain, which lacks the conserved residues necessary for ATP binding and catalytic activity. TRRAP also contains many motifs that may be critical for protein-protein interactions. TRRAP is a common component of many histone acetyltransferase (HAT) complexes, and is responsible for the recruitment of these complexes to chromatin during transcription, replication, and DNA repair. TRRAP also exists in non-HAT complexes such as the p400 and MRN complexes, which are implicated in ATP-dependent remodeling and DNA repair, respectively. The TRRAP pseudokinase domain subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as the typical serine/threonine/tyrosine protein kinases (PKs), aminoglycoside phosphotransferase, choline kinase, and RIO kinases.
