Rho guanine nucleotide exchange factor Pleckstrin homology domain; p190RhoGEF (also called RIP2 or ARHGEF28) belongs to regulator of G-protein signaling (RGS) domain-containing RhoGEFs that are RhoA-selective and directly activated by the Galpha12/13 family of heterotrimeric G proteins. In addition to the Dbl homology (DH)-PH domain, p190RhoGEF contains an N-terminal C1 (Protein kinase C conserved region 1) domain. The DH-PH domains bind and catalyze the exchange of GDP for GTP on RhoA. 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) superfamily; 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 the motif HX12CX2CXnCX2CX4HX2CX7C, where C and H are cysteine and histidine, respectively; X represents other residues; and n is either 13 or 14. 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. PKC C1 domains play roles in membrane translocation and activation of the enzyme.

Rho guanine nucleotide exchange factor 2 Pleckstrin homology (PH) domain; ARHGEF2, also called GEF-H1, acts as guanine nucleotide exchange factor (GEF) for RhoA GTPases. It is thought to play a role in actin cytoskeleton reorganization in different tissues since its activation induces formation of actin stress fibers. ARHGEF2 contains a C1 domain followed by Dbl-homology (DH) and pleckstrin-homology (PH) domains which bind and catalyze the exchange of GDP for GTP on RhoA. 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.

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 190 kDa guanine nucleotide exchange factor (p190RhoGEF) and similar proteins; p190RhoGEF, also called Rho guanine nucleotide exchange factor (RGNEF), Rho guanine nucleotide exchange factor 28 (ARHGEF28), or RIP2, is a brain-enriched, RhoA-specific guanine nucleotide exchange factor that regulates signaling pathways downstream of integrins and growth factor receptors. It is involved in axonal branching, synapse formation and dendritic morphogenesis, as well as in focal adhesion formation, cell motility and B-lymphocytes activation. In addition to the Dbl homology (DH)-PH domain, p190RhoGEF contains an N-terminal C1 (Protein kinase C conserved region 1) 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.

protein kinase C conserved region 1 (C1 domain) found in A-kinase anchor protein 13 (AKAP-13) and similar proteins; AKAP-13, also called AKAP-Lbc, breast cancer nuclear receptor-binding auxiliary protein (Brx-1), guanine nucleotide exchange factor Lbc, human thyroid-anchoring protein 31, lymphoid blast crisis oncogene (LBC oncogene), non-oncogenic Rho GTPase-specific GTP exchange factor, protein kinase A-anchoring protein 13 (PRKA13), or p47, is a scaffold protein that plays an important role in assembling signaling complexes downstream of several types of G protein-coupled receptors (GPCRs). It activates RhoA in response to GPCR signaling via its function as a Rho guanine nucleotide exchange factor. It may also activate other Rho family members. AKAP-13 plays a role in cell growth, cell development and actin fiber formation. Its Rho-GEF activity is regulated by protein kinase A (PKA), through binding and phosphorylation. Alternative splicing of this gene in humans has at least 3 transcript variants encoding different isoforms (i.e. proto-/onco-Lymphoid blast crisis, Lbc and breast cancer nuclear receptor-binding auxiliary protein, and Brx) that contain a C1 domain followed by a dbl oncogene homology (DH) domain and a PH domain which are required for full transforming activity.

PDZ Rho guanine nucleotide exchange factor Pleckstrin homology (PH) domain; PRG (also called RhoGEF11) belongs to regulator of G-protein signaling (RGS) domain-containing RhoGEFs that are RhoA-selective and directly activated by the Galpha12/13 family of heterotrimeric G proteins. RhoGEFs activate Rho GTPases regulating cytoskeletal structure, gene transcription, and cell migration. PRG contains an N-terminal PDZ domain, a regulators of G-protein signaling-like (RGSL) domain, a linker region, and a C-terminal Dbl-homology (DH) and pleckstrin-homology (PH) domains which bind and catalyze the exchange of GDP for GTP on RhoA. As is the case in p115-RhoGEF, it is thought that the PRG activated by relieving autoinhibition caused by the linker region. 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.

protein kinase C conserved region 1 (C1 domain) superfamily; 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 the motif HX12CX2CXnCX2CX4HX2CX7C, where C and H are cysteine and histidine, respectively; X represents other residues; and n is either 13 or 14. 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. PKC C1 domains play roles in membrane translocation and activation of the enzyme.

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.

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.

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.

first protein kinase C conserved region 1 (C1 domain) found in classical (or conventional) protein kinase C (cPKC), novel protein kinase C (nPKC), and similar proteins; PKCs are classified into three groups (classical, atypical, and novel) depending on their mode of activation and the structural characteristics of their regulatory domains. 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.

second protein kinase C conserved region 1 (C1 domain) found in diacylglycerol kinase eta (DAG kinase eta) and similar proteins; Diacylglycerol (DAG) kinase (EC 2.7.1.107) is a lipid kinase that phosphorylates diacylglycerol to form phosphatidic acid. DAG kinase eta, also called diglyceride kinase eta (DGK-eta), plays a key role in promoting cell growth. 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. The diacylglycerol kinase eta gene, DGKH, is a replicated risk gene of bipolar disorder (BPD). DAG kinase eta contains two copies of the 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.

second protein kinase C conserved region 1 (C1 domain) found in novel protein kinase C (nPKC) theta, delta, and similar proteins; PKCs are classified into three groups (classical, atypical, and novel) depending on their mode of activation and the structural characteristics of their regulatory domain. nPKCs are calcium-independent, but require DAG (1,2-diacylglycerol) and phosphatidylserine (PS) for activity. PKC-theta is selectively expressed in T-cells and plays an important and non-redundant role in several aspects of T-cell biology. PKC-delta plays a role in cell cycle regulation and programmed cell death in many cell types. 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.

protein kinase C conserved region 1 (C1 domain) found in VAV3 protein; VAV3 is ubiquitously expressed and functions as a phosphorylation-dependent guanine nucleotide exchange factor (GEF) for RhoA, RhoG, and Rac1. Its function has been implicated in the hematopoietic, bone, cerebellar, and cardiovascular systems. VAV3 is essential in axon guidance in neurons that control blood pressure and respiration. It is overexpressed in prostate cancer cells and plays a role in regulating androgen receptor transcriptional activity. VAV proteins contain several domains that enable their function: N-terminal calponin homology (CH), acidic, RhoGEF (also called Dbl-homologous or DH), Pleckstrin Homology (PH), C1 (zinc finger), SH2, and two SH3 domains. 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.

second protein kinase C conserved region 1 (C1 domain) found in classical (or conventional) protein kinase C (cPKC), novel protein kinase C (nPKC), and similar proteins; PKCs are classified into three groups (classical, atypical, and novel) depending on their mode of activation and the structural characteristics of their regulatory domain. 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 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.
