Ras-associating (RA) domain found in Ras-association domain-containing protein 1 (RASSF1); RASSF1 is a member of a family of six related RASSF1-6 proteins (the classical RASSF proteins). RASSF1 has eight transcripts (A-H) arising from alternative splicing and differential promoter usage. With the exception of some minor splice variants (RASSF1F and RASSF1G), RASSF1 contains an RA domain and a C-terminal SARAH protein-protein interaction motif. The RA domain of the classical RASSF proteins has a beta-grasp ubiquitin-like fold with low sequence similarity to ubiquitin. The RA domain mediates interactions with Ras and other small GTPases, and the SARAH domain mediates protein-protein interactions crucial in the pathways that induce cell cycle arrest and apoptosis. RASSF1A and 1C are the most extensively studied RASSF1 with both localized to microtubules and involved in regulation of growth and migration.

Novel Ras effector 1 C-terminal SARAH (Sav/Rassf/Hpo) domain; The Nore1-SARAH, C-terminal, domain of Nore1, the tumour-suppressor, a novel Ras effector, has a characteriztic coiled-coil structure. It is a small helical module that is important in signal-transduction networks. The recombinant SARAH domain of Nore1 crystallizes as an anti-parallel homodimer with representative characteriztics of coiled coils. The central function of the SARAH domain seems to be the mediation of homo- and hetero-oligomerization between SARAH domain-containing proteins. Nore1 forms homo- and hetero complexes through its C-terminal SARAH (Sav/Rassf/Hpo) domain.

Ras-associating (RA) domain found in Ras-association domain family members, RASSF1, RASSF3, and RASSF5; The RASSF family of proteins shares a conserved RalGDS/AF6 Ras association (RA) domain which is located either at the C-terminus (RASSF1-6, the classical group) or at the N-terminus (RASSF7-10). RASSF1-6 contains a conserved SARAH (Salvador/RASSF/Hpo) motif adjacent to the RA domain that functions in scaffolding and regulatory interactions. The RA domain of the classical RASSF proteins has a beta-grasp ubiquitin-like fold with low sequence similarity to ubiquitin. Classical RASSF members interact either directly or indirectly with activated Ras. Ras proteins are small GTPases that are involved in cellular signal transduction. The classical RASSF proteins seem to modulate some of the growth inhibitory responses mediated by Ras and may serve as tumor suppressor genes. This family contains RASSF1, RASSF3, and RASSF5.

protein kinase C conserved region 1 (C1 domain) found in RAS guanyl-releasing protein 1 (RASGRP1) and similar proteins; RASGRP1, also called calcium and DAG-regulated guanine nucleotide exchange factor II (CalDAG-GEFII) or Ras guanyl-releasing protein, functions as a calcium- and diacylglycerol (DAG)-regulated nucleotide exchange factor specifically activating Ras through the exchange of bound GDP for GTP. It 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. 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.

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. 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.

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. PKC-eta increases glioblastoma multiforme (GBM) proliferation and resistance to radiation, and is being developed as a therapeutic target for the management of GBM.

first 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 domains. 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 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.

Ras-associating (RA) domain found in Ras-association domain-containing protein 4 (RASSF4); RASSF4 is a member of a family of six related classical RASSF1-6 proteins and is broadly expressed in normal tissues. RASSF4 expression is reduced in tumor cell lines and primary tumors by promoter specific hypermethylation. RASSF4 contains the RA and SARAH domains. The RA domain of the classical RASSF protein family has the beta-grasp ubiquitin-like fold with low sequence similarity to ubiquitin. RA domains mediate interactions with Ras and other small GTPases, and SARAH domains mediate protein-protein interactions crucial in the pathways that induce cell cycle arrest and apoptosis. RASSF4 inhibits lung cancer cell proliferation and invasion.

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. 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.

Ras-associating (RA) domain found in Ras-association domain-containing protein 2 (RASSF2); RASSF2 is a member of a family of six related classical RASSF1-6 proteins. The RASSF2 gene is transcribed into two major isoforms (A and C). RASSF2 is structurally related to RASSF1A but unlike RASSF1A It is primarily a nuclear protein. RASSF2 contains the RA and SARAH domains. The RA domain of the classical RASSF protein family has the beta-grasp ubiquitin-like fold with low sequence similarity to ubiquitin. RA domains mediate interactions with Ras and other small GTPases, and SARAH domains mediate protein-protein interactions crucial in the pathways that induce cell cycle arrest and apoptosis. RASSF2 is inactivated in different cancers and cancer cell lines by promoter methylation and loss of expression, implicating the correlation and significance of RASSF2 in tumorigenesis. In addition to regulating apoptosis and proliferation RASSF2 may have other functions as RASSF2 knockout mice develop normally for the first two weeks but then develop growth retardation and die 4 weeks after birth.

protein kinase C conserved region 1 (C1 domain) found in the Myotonic dystrophy kinase-related Cdc42-binding kinase (MRCK) family; MRCK is thought to be a coincidence detector of signaling by the small GTPase Cdc42 and phosphoinositides. MRCK/Cdc42 signaling mediates myosin-dependent cell motility. MRCK has been shown to promote cytoskeletal reorganization, which affects many biological processes. Three isoforms of MRCK are known, named alpha, beta and gamma. MRCKgamma is expressed in heart and skeletal muscles, unlike MRCKalpha and MRCKbeta, which are expressed ubiquitously. MRCK consists of a serine/threonine kinase domain, a cysteine rich (C1) region, a PH domain and a p21 binding motif. This model corresponds to 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.

protein kinase C conserved region 1 (C1 domain) found in unconventional myosin-IXb and similar proteins; Myosin-IXb, also called unconventional myosin-9b (Myo9b), is an actin-dependent motor protein of the unconventional myosin IX class. It is expressed abundantly in tissues of the immune system, like lymph nodes, thymus, and spleen, and in several immune cells including dendritic cells, macrophages and CD4+ T cells. Myosin-IXb contains a Ras-associating (RA) domain, a motor domain, a protein kinase C conserved region 1 (C1), and a Rho GTPase activating (RhoGAP) domain. Myosin-IXb acts as a motorized signaling molecule that links Rho signaling to the dynamic actin cytoskeleton. It regulates leukocyte migration by controlling RhoA signaling. Myosin-IXb is also involved in the development of autoimmune diseases, including rheumatoid arthritis, systemic lupus erythematosus, and type 1 diabetes. Moreover, Myosin-IXb is a ROBO-interacting protein that suppresses RhoA activity in lung cancer cells. 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.

C-terminal SARAH domain found in Ras-association domain proteins, RASSF2, RASSF4, and RASSF6; The RASSF subfamily of proteins shares a conserved RalGDS/AF6 Ras association (RA) domain which is located either at the C-terminus (RASSF1-6, the classical group) or at the N-terminus (RASSF7-10). The classical RASSF proteins seem to modulate some of the growth inhibitory responses mediated by Ras and may serve as tumor suppressor genes. They interact either directly or indirectly with activated Ras. Ras proteins are small GTPases that are involved in cellular signal transduction. RASSF1-6 contain a conserved C-terminal SARAH (Salvador-RassF-Hippo) motif adjacent to the RA domain that functions in scaffolding and regulatory interactions. The RA domain of the classical RASSF proteins has a beta-grasp ubiquitin-like fold with low sequence similarity to ubiquitin. This model corresponds to the SARAH domain of RASSF2, RASSF4, and RASSF6. It is a characteristic coiled-coil structure that is important in signal-transduction networks. The central function of the SARAH domain is the mediation of homo- and heterodimerization between SARAH domain-containing proteins.

first protein kinase C conserved region 1 (C1 domain) found in type II diacylglycerol kinases; Diacylglycerol (DAG) kinase (EC 2.7.1.107) is a lipid kinase that phosphorylates diacylglycerol to form phosphatidic acid. Type II DAG kinases (DGKs) contain 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. Three DGK isozymes (delta, eta and kappa) are classified as type II. DAG kinase delta, also called 130 kDa DAG 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. DAG kinase eta, also called diglyceride kinase eta (DGK-eta), plays a key role in promoting cell growth. The DAG kinase eta gene, DGKH, is a replicated risk gene of bipolar disorder (BPD). DAG kinase kappa is also called diglyceride kinase kappa (DGK-kappa) or 142 kDa DAG kinase. Members of this family contain 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.

protein kinase C conserved region 1 (C1 domain) found in male germ cell RacGap (MgcRacGAP) and similar proteins; MgcRacGAP, also called Rac GTPase-activating protein 1 (RACGAP1) or protein CYK4, plays an important dual role in cytokinesis: i) it is part of centralspindlin-complex, together with the mitotic kinesin MKLP1, which is critical for the structure of the central spindle by promoting microtuble bundling; and ii) after phosphorylation by aurora B, MgcRacGAP becomes an effective regulator of RhoA and plays an important role in the assembly of the contractile ring and the initiation of cytokinesis. MgcRacGAP-like proteins contain an N-terminal C1 domain, and a C-terminal RhoGAP domain. 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.
