 1636-2057 0e+00

Dock Homology Region 2, a GEF domain, of Class C Dedicator of Cytokinesis 8; Dock8, also called Zizimin-related 3 (Zir3), is an atypical guanine nucleotide exchange factor (GEF) that lacks the conventional Dbl homology (DH) domain. As a GEF, it activates the small GTPases Rac1 and Cdc42 by exchanging bound GDP for free GTP. Dock8 is highly expressed in the immune system and it regulates T and B cell numbers and functions. It plays essential roles in humoral immune responses and the proper formation of B cell immunological synapses. Dock8 deficiency is a primary immune deficiency that results in extreme susceptibility to cutaneous viral infections, elevated IgE levels, and eosinophilia. It was originally described as an autosomal recessive form of hyper IgE syndrome (AR-HIES). DOCK proteins are divided into four classes (A-D) based on sequence similarity and domain architecture; class C includes Dock6, 7 and 8. All DOCKs contain two homology domains: the DHR-1 (Dock homology region-1), also called CZH1 (CED-5, Dock180, and MBC-zizimin homology 1), and DHR-2 (also called CZH2 or Docker). The DHR-1 domain binds phosphatidylinositol-3,4,5-triphosphate. This alignment model represents the DHR-2 domain of Dock8, which contains the catalytic GEF activity for Rac and/or Cdc42.

 559-739 2.37e-109

C2 domains found in Dedicator Of CytoKinesis (Dock) class C proteins; Dock-C is one of 4 classes of Dock family proteins. The members here include: Dock6/Zir1, Dock7/Zir2, and Dock8/Zir3. Dock-C members are GEFs for both Rac and Cdc42. In addition to the C2 domain (AKA Dock homology region (DHR)-1, CED-5, Dock180, MBC-zizimin homology (CZH) 1) and the DHR-2 (AKA CZH2, or Docker), which all Dock180-related proteins have, Dock-C members contain a functionally uncharacterized domain upstream of the C2 domain. DHR-2 has the catalytic activity for Rac and/or Cdc42, but is structurally unrelated to the DH domain. The C2/DHR-1 domains of Dock180 and Dock4 have been shown to bind phosphatidylinositol-3, 4, 5-triphosphate (PtdIns(3,4,5)P3). The C2 domain was first identified in PKC. 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.

 56-166 5.28e-41

Dedicator of cytokinesis C/D, N terminal; This entry represents the N-terminal domain of the DOCK-C subfamily (DOCK 6, 7, 8) and DOCK-D subfamily (DOCK 9, 10, 11). DOCK family members are evolutionarily conserved guanine nucleotide exchange factors (GEFs) for Rho-family GTPases, required during several cellular processes, such as cell motility and phagocytosis. DOCK proteins are categorized into four subfamilies based on their sequence homology: DOCK-A (DOCK1/180, 2, 5), DOCK-B subfamily (DOCK3, 4), DOCK-C subfamily (DOCK6, 7, 8), DOCK-D subfamily (DOCK9, 10, 11).

C2 domain in Dock180 and Zizimin proteins; The Dock180/Dock1 and Zizimin proteins are atypical GTP/GDP exchange factors for the small GTPases Rac and Cdc42 and are implicated cell-migration and phagocytosis. Across all Dock180 proteins, two regions are conserved: C-terminus termed CZH2 or DHR2 (or the Dedicator of cytokinesis) whereas CZH1/DHR1 contain a new family of the C2 domain.

DHR-2, Lobe A; This entry represents a conserved region within a number of eukaryotic dedicator of cytokinesis proteins (DOCK), which are guanine nucleotide exchange factors (GEFs), that activate some small GTPases by exchanging bound GDP for free GTP such as Rac. These proteins have a DOCK-homology region 1 (DHR-1, also known as DOCK-type C2 domain) at the N-terminus and a DHR-2 (also known as DOCKER domain) at the C-terminal. The DHR-2 is a GEF catalytic domain organized into three lobes, A, B and C, with the Rho-family binding site and catalytic centre generated entirely from lobes B and C. This entry represents Lobe A, formed from an antiparallel array of alpha helices that adopts a tetratricopeptide repeat-like fold, which through extensive contacts with lobe B, stabilizes DHR-2 domain.

Dedicator of cytokinesis C/D, N terminal; This entry represents the N-terminal domain of the DOCK-C subfamily (DOCK 6, 7, 8) and DOCK-D subfamily (DOCK 9, 10, 11). DOCK family members are evolutionarily conserved guanine nucleotide exchange factors (GEFs) for Rho-family GTPases, required during several cellular processes, such as cell motility and phagocytosis. DOCK proteins are categorized into four subfamilies based on their sequence homology: DOCK-A (DOCK1/180, 2, 5), DOCK-B subfamily (DOCK3, 4), DOCK-C subfamily (DOCK6, 7, 8), DOCK-D subfamily (DOCK9, 10, 11).

 1636-2057 0e+00

Dock Homology Region 2, a GEF domain, of Class C Dedicator of Cytokinesis 8; Dock8, also called Zizimin-related 3 (Zir3), is an atypical guanine nucleotide exchange factor (GEF) that lacks the conventional Dbl homology (DH) domain. As a GEF, it activates the small GTPases Rac1 and Cdc42 by exchanging bound GDP for free GTP. Dock8 is highly expressed in the immune system and it regulates T and B cell numbers and functions. It plays essential roles in humoral immune responses and the proper formation of B cell immunological synapses. Dock8 deficiency is a primary immune deficiency that results in extreme susceptibility to cutaneous viral infections, elevated IgE levels, and eosinophilia. It was originally described as an autosomal recessive form of hyper IgE syndrome (AR-HIES). DOCK proteins are divided into four classes (A-D) based on sequence similarity and domain architecture; class C includes Dock6, 7 and 8. All DOCKs contain two homology domains: the DHR-1 (Dock homology region-1), also called CZH1 (CED-5, Dock180, and MBC-zizimin homology 1), and DHR-2 (also called CZH2 or Docker). The DHR-1 domain binds phosphatidylinositol-3,4,5-triphosphate. This alignment model represents the DHR-2 domain of Dock8, which contains the catalytic GEF activity for Rac and/or Cdc42.

Dock Homology Region 2, a GEF domain, of Class C Dedicator of Cytokinesis 7; Dock7, also called Zizimin-related 2 (Zir2), is an atypical guanine nucleotide exchange factor (GEF) that lacks the conventional Dbl homology (DH) domain. As a GEF, it activates the small GTPases Rac1 and Cdc42 by exchanging bound GDP for free GTP. It plays a critical role in the initial specification of axon formation in hippocampal neurons. It affects neuronal polarity by regulating microtubule dynamics. Dock7 also plays a role in controlling myelination by Schwann cells. It may also play important roles in the function and distribution of dermal and follicular melanocytes. DOCK proteins are divided into four classes (A-D) based on sequence similarity and domain architecture; class C includes Dock6, 7 and 8. All DOCKs contain two homology domains: the DHR-1 (Dock homology region-1), also called CZH1 (CED-5, Dock180, and MBC-zizimin homology 1), and DHR-2 (also called CZH2 or Docker).

Dock Homology Region 2, a GEF domain, of Class D Dedicator of Cytokinesis proteins; DOCK proteins are atypical guanine nucleotide exchange factors (GEFs) that lack the conventional Dbl homology (DH) domain. As GEFs, they activate small GTPases by exchanging bound GDP for free GTP. They are divided into four classes (A-D) based on sequence similarity and domain architecture; class D, also called the Zizimin subfamily, includes Dock9, 10 and 11. Class D Docks are specific GEFs for Cdc42. Dock9 plays important roles in spine formation and dendritic growth. Dock10 and Dock11 are preferentially expressed in lymphocytes. All DOCKs contain two homology domains: the DHR-1 (Dock homology region-1), also called CZH1 (CED-5, Dock180, and MBC-zizimin homology 1), and DHR-2 (also called CZH2 or Docker). The DHR-1 domain binds phosphatidylinositol-3,4,5-triphosphate. This alignment model represents the DHR-2 domain of class D DOCKs, which contains the catalytic GEF activity for Cdc42. Class D DOCKs also contain a Pleckstrin homology (PH) domain at the N-terminus.

Dock Homology Region 2, a GEF domain, of Class D Dedicator of Cytokinesis 11; Dock11, also called Zizimin2 or activated Cdc42-associated GEF (ACG), is an atypical guanine nucleotide exchange factor (GEF) that lacks the conventional Dbl homology (DH) domain. As a GEF, it activates the small GTPase Cdc42 by exchanging bound GDP for free GTP. Dock11 is predominantly expressed in lymphocytes and is found in high levels in germinal center B lymphocytes after T cell dependent antigen immunization. DOCK proteins are divided into four classes (A-D) based on sequence similarity and domain architecture; class D includes Dock9, 10 and 11. All DOCKs contain two homology domains: the DHR-1 (Dock homology region-1), also called CZH1 (CED-5, Dock180, and MBC-zizimin homology 1), and DHR-2 (also called CZH2 or Docker).

Dock Homology Region 2, a GEF domain, of Dedicator of Cytokinesis proteins; DOCK proteins comprise a family of atypical guanine nucleotide exchange factors (GEFs) that lack the conventional Dbl homology (DH) domain. As GEFs, they activate the small GTPases Rac and Cdc42 by exchanging bound GDP for free GTP. They are also called the CZH (CED-5, Dock180, and MBC-zizimin homology) family, after the first family members identified. Dock180 was first isolated as a binding partner for the adaptor protein Crk. The Caenorhabditis elegans protein, Ced-5, is essential for cell migration and phagocytosis, while the Drosophila ortholog, Myoblast city (MBC), is necessary for myoblast fusion and dorsal closure. DOCKs are divided into four classes (A-D) based on sequence similarity and domain architecture: class A includes Dock1 (or Dock180), 2 and 5; class B includes Dock3 and 4; class C includes Dock6, 7, and 8; and class D includes Dock9, 10 and 11. All DOCKs contain two homology domains: the DHR-1 (Dock homology region-1), also called CZH1, and DHR-2 (also called CZH2 or Docker). This alignment model represents the DHR-2 domain of DOCK proteins, which contains the catalytic GEF activity for Rac and/or Cdc42.

 559-739 2.37e-109

C2 domains found in Dedicator Of CytoKinesis (Dock) class C proteins; Dock-C is one of 4 classes of Dock family proteins. The members here include: Dock6/Zir1, Dock7/Zir2, and Dock8/Zir3. Dock-C members are GEFs for both Rac and Cdc42. In addition to the C2 domain (AKA Dock homology region (DHR)-1, CED-5, Dock180, MBC-zizimin homology (CZH) 1) and the DHR-2 (AKA CZH2, or Docker), which all Dock180-related proteins have, Dock-C members contain a functionally uncharacterized domain upstream of the C2 domain. DHR-2 has the catalytic activity for Rac and/or Cdc42, but is structurally unrelated to the DH domain. The C2/DHR-1 domains of Dock180 and Dock4 have been shown to bind phosphatidylinositol-3, 4, 5-triphosphate (PtdIns(3,4,5)P3). The C2 domain was first identified in PKC. 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.

 1639-2057 1.08e-108

Dock Homology Region 2, a GEF domain, of Class D Dedicator of Cytokinesis 9; Dock9, also called Zizimin1, is an atypical guanine nucleotide exchange factor (GEF) that lacks the conventional Dbl homology (DH) domain. As a GEF, it activates the small GTPase Cdc42 by exchanging bound GDP for free GTP. It plays important roles in spine formation and dendritic growth. DOCK proteins are divided into four classes (A-D) based on sequence similarity and domain architecture; class D includes Dock9, 10 and 11. All DOCKs contain two homology domains: the DHR-1 (Dock homology region-1), also called CZH1 (CED-5, Dock180, and MBC-zizimin homology 1), and DHR-2 (also called CZH2 or Docker). The DHR-1 domain binds phosphatidylinositol-3,4,5-triphosphate. This alignment model represents the DHR-2 domain of Dock9, which contains the catalytic GEF activity for Cdc42. Class D DOCKs also contain a Pleckstrin homology (PH) domain at the N-terminus.

Dock Homology Region 2, a GEF domain, of Class D Dedicator of Cytokinesis 10; Dock10, also called Zizimin3, is an atypical guanine nucleotide exchange factor (GEF) that lacks the conventional Dbl homology (DH) domain. As a GEF, it activates the small GTPase Cdc42 by exchanging bound GDP for free GTP. Dock10 is preferentially expressed in lymphocytes and may play a role in interleukin-4 induced activation of B cells. It may also play a role in the invasion of tumor cells. DOCK proteins are divided into four classes (A-D) based on sequence similarity and domain architecture; class D includes Dock9, 10 and 11. All DOCKs contain two homology domains: the DHR-1 (Dock homology region-1), also called CZH1 (CED-5, Dock180, and MBC-zizimin homology 1), and DHR-2 (also called CZH2 or Docker).

C2 domain in Dock180 and Zizimin proteins; The Dock180/Dock1 and Zizimin proteins are atypical GTP/GDP exchange factors for the small GTPases Rac and Cdc42 and are implicated cell-migration and phagocytosis. Across all Dock180 proteins, two regions are conserved: C-terminus termed CZH2 or DHR2 (or the Dedicator of cytokinesis) whereas CZH1/DHR1 contain a new family of the C2 domain.

DHR-2, Lobe A; This entry represents a conserved region within a number of eukaryotic dedicator of cytokinesis proteins (DOCK), which are guanine nucleotide exchange factors (GEFs), that activate some small GTPases by exchanging bound GDP for free GTP such as Rac. These proteins have a DOCK-homology region 1 (DHR-1, also known as DOCK-type C2 domain) at the N-terminus and a DHR-2 (also known as DOCKER domain) at the C-terminal. The DHR-2 is a GEF catalytic domain organized into three lobes, A, B and C, with the Rho-family binding site and catalytic centre generated entirely from lobes B and C. This entry represents Lobe A, formed from an antiparallel array of alpha helices that adopts a tetratricopeptide repeat-like fold, which through extensive contacts with lobe B, stabilizes DHR-2 domain.

 559-739 1.47e-53

C2 domains found in Dedicator Of CytoKinesis (Dock) class C proteins; Dock-D is one of 4 classes of Dock family proteins. The members here include: Dock9/Zizimin1, Dock10/Zizimin3, and Dock11/Zizimin2/ACG (activated Cdc42-associated GEF). Dock-D are Cdc42-specific GEFs. In addition to the C2 domain (AKA Dock homology region (DHR)-1, CED-5, Dock180, MBC-zizimin homology (CZH) 1) and the DHR-2 (AKA CZH2, or Docker), which all Dock180-related proteins have, Dock-D members contain a functionally uncharacterized domain and a PH domain upstream of the C2 domain. DHR-2 has the catalytic activity for Rac and/or Cdc42, but is structurally unrelated to the DH domain. The C2/DHR-1 domains of Dock180 and Dock4 have been shown to bind phosphatidylinositol-3, 4, 5-triphosphate (PtdIns(3,4,5)P3). The PH domain broadly binds to phospholipids and is thought to be involved in targeting the plasma membrane. The C2 domain was first identified in PKC. 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.

C2 domains found in Dedicator Of CytoKinesis 1 (DOCK 180) and related proteins; Dock180 was first identified as an 180kd proto-oncogene product c-Crk-interacting protein involved in actin cytoskeletal changes. It is now known that it has Rac-specific GEF activity, but lacks the conventional Dbl homology (DH) domain. There are 10 additional related proteins that can be divided into four classes based on sequence similarity and domain organization: Dock-A which includes Dock180/Dock1, Dock2, and Dock5; Dock-B which includes Dock3/MOCA (modifier of cell adhesion) and Dock4; Dock-C which includes Dock6/Zir1, Dock7/Zir2, and Dock8/Zir3; and Dock-D, which includes Dock9/Zizimin1, Dock10/Zizimin3, and Dock11/Zizimin2/ACG (activated Cdc42-associated GEF). Most of members of classes Dock-A and Dock-B are the GEFs specific for Rac. Those of Dock-D are Cdc42-specific GEFs while those of Dock-C are the GEFs for both. All Dock180-related proteins have two common homology domains: the C2 domain (AKA Dock homology region (DHR)-1, CED-5, Dock180, MBC-zizimin homology (CZH) 1) and the DHR-2 (AKA CZH2, or Docker). DHR-2 has the catalytic activity for Rac and/or Cdc42, but is structurally unrelated to the DH domain. The C2/DHR-1 domains of Dock180 and Dock4 have been shown to bind phosphatidylinositol-3, 4, 5-triphosphate (PtdIns(3,4,5)P3). The C2 domain was first identified in PKC. 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.

DHR-2, Lobe C; DOCK (dedicator of cytokinesis) proteins are guanine nucleotide exchange factors (GEFs) that activate some small GTPases, such as Rac or Cdc42, by exchanging bound GDP for free GTP to control cell migration, morphogenesis, and phagocytosis. These proteins share a DOCK-type C2 domain (also termed the DOCK-homology region (DHR)-1) at the N-terminal, and the DHR-2 domain (also termed the DOCKER domain) at the C-terminal. DHR-2 is the GEF catalytic domain organized into three lobes A, B and C, with the Rho-family binding site and catalytic centre generated entirely from lobes B and C. This entry represents Lobe C which form an antiparallel four alpha-helical bundle and contains a loop known as the nucleotide sensor characterized by a conserved valine residue essential for catalytic activity.

Dedicator of cytokinesis C/D, N terminal; This entry represents the N-terminal domain of the DOCK-C subfamily (DOCK 6, 7, 8) and DOCK-D subfamily (DOCK 9, 10, 11). DOCK family members are evolutionarily conserved guanine nucleotide exchange factors (GEFs) for Rho-family GTPases, required during several cellular processes, such as cell motility and phagocytosis. DOCK proteins are categorized into four subfamilies based on their sequence homology: DOCK-A (DOCK1/180, 2, 5), DOCK-B subfamily (DOCK3, 4), DOCK-C subfamily (DOCK6, 7, 8), DOCK-D subfamily (DOCK9, 10, 11).

This entry represents Lobe B which adopts an unusual architecture of two antiparallel beta sheets disposed in a loosely packed orthogonal arrangement. This lobe changes its position relative to lobe C and the bound GTPase, which suggests that lobe B distinguishes between the switch 1 conformations of Rac1 and Cdc42.

Dock Homology Region 2, a GEF domain, of Class B Dedicator of Cytokinesis proteins; DOCK proteins are atypical guanine nucleotide exchange factors (GEFs) that lack the conventional Dbl homology (DH) domain. As GEFs, they activate small GTPases by exchanging bound GDP for free GTP. They are divided into four classes (A-D) based on sequence similarity and domain architecture; class B includes Dock3 and 4. Dock3 is a specific GEF for Rac and it regulates N-cadherin dependent cell-cell adhesion, cell polarity, and neuronal morphology. It promotes axonal growth by stimulating actin polymerization and microtubule assembly. Dock4 activates the Ras family GTPase Rap1, probably indirectly through interaction with Rap regulatory proteins. It plays a role in regulating dendritic growth and branching in hippocampal neurons, where it is highly expressed. All DOCKs contain two homology domains: the DHR-1 (Dock homology region-1), also called CZH1 (CED-5, Dock180, and MBC-zizimin homology 1), and DHR-2 (also called CZH2 or Docker). The DHR-1 domain binds phosphatidylinositol-3,4,5-triphosphate. This alignment model represents the DHR-2 domain of class B DOCKs, which contains the catalytic GEF activity for Rac and/or Cdc42. Class B DOCKs also contain an SH3 domain at the N-terminal region and a PxxP motif at the C-terminus.

As GEFs, they activate small GTPases by exchanging bound GDP for free GTP. They are divided into four classes (A-D) based on sequence similarity and domain architecture; class A includes Dock1, 2 and 5. Class A DOCKs are specific GEFs for Rac. Dock1 interacts with the scaffold protein Elmo and the resulting complex functions upstream of Rac in many biological events including phagocytosis of apoptotic cells, cell migration and invasion. Dock2 plays an important role in lymphocyte migration and activation, T-cell differentiation, neutrophil chemotaxis, and type I interferon induction. Dock5 functions upstream of Rac1 to regulate osteoclast function. All DOCKs contain two homology domains: the DHR-1 (Dock homology region-1), also called CZH1 (CED-5, Dock180, and MBC-zizimin homology 1), and DHR-2 (also called CZH2 or Docker).

 1794-2054 2.55e-11

Dock Homology Region 2, a GEF domain, of Class A Dedicator of Cytokinesis 2; Dock2 is a hematopoietic cell-specific, class A DOCK and is an atypical guanine nucleotide exchange factor (GEF) that lacks the conventional Dbl homology (DH) domain. As a GEF, it activates small GTPases by exchanging bound GDP for free GTP. It plays an important role in lymphocyte migration and activation, T-cell differentiation, neutrophil chemotaxis, and type I interferon induction. DOCK proteins are divided into four classes (A-D) based on sequence similarity and domain architecture; class A includes Dock1, 2 and 5. All DOCKs contain two homology domains: the DHR-1 (Dock homology region-1), also called CZH1 (CED-5, Dock180, and MBC-zizimin homology 1), and DHR-2 (also called CZH2 or Docker). The DHR-1 domain binds phosphatidylinositol-3,4,5-triphosphate. This alignment model represents the DHR-2 domain of Dock2, which contains the catalytic GEF activity for Rac and/or Cdc42. Class A DOCKs, like Dock2, are specific GEFs for Rac and they contain an SH3 domain at the N-terminal region and a PxxP motif at the C-terminus.

Dock Homology Region 2, a GEF domain, of Class A Dedicator of Cytokinesis 1; Dock1, also called Dock180, is an atypical guanine nucleotide exchange factor (GEF) that lacks the conventional Dbl homology (DH) domain. As a GEF, it activates small GTPases by exchanging bound GDP for free GTP. Dock1 interacts with the scaffold protein Elmo and the resulting complex functions upstream of Rac in many biological events including phagocytosis of apoptotic cells, cell migration and invasion. In the nervous system, it mediates attractive responses to netrin-1 and thus, plays a role in axon outgrowth and pathfinding. DOCK proteins are divided into four classes (A-D) based on sequence similarity and domain architecture; class A includes Dock1, 2 and 5. All DOCKs contain two homology domains: the DHR-1 (Dock homology region-1), also called CZH1 (CED-5, Dock180, and MBC-zizimin homology 1), and DHR-2 (also called CZH2 or Docker). The DHR-1 domain binds phosphatidylinositol-3,4,5-triphosphate. This alignment model represents the DHR-2 domain of Dock1, which contains the catalytic GEF activity for Rac and/or Cdc42. Class A DOCKs, like Dock1, are specific GEFs for Rac and they contain an SH3 domain at the N-terminal region and a PxxP motif at the C-terminus.

 578-656 9.06e-07

C2 domains found in Dedicator Of CytoKinesis (Dock) class A proteins; Dock-A is one of 4 classes of Dock family proteins. The members here include: Dock180/Dock1, Dock2, and Dock5. Most of these members have been shown to be GEFs specific for Rac. Dock5 has not been well characterized to date, but most likely also is a GEF specific for Rac. In addition to the C2 domain (AKA Dock homology region (DHR)-1, CED-5, Dock180, MBC-zizimin homology (CZH) 1) and the DHR-2 (AKA CZH2, or Docker), which all Dock180-related proteins have, Dock-A members contain a proline-rich region and a SH3 domain upstream of the C2 domain. DHR-2 has the catalytic activity for Rac and/or Cdc42, but is structurally unrelated to the DH domain. The C2/DHR-1 domains of Dock180 and Dock4 have been shown to bind phosphatidylinositol-3, 4, 5-triphosphate (PtdIns(3,4,5)P3). The C2 domain was first identified in PKC. 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.

C2 domains found in Dedicator Of CytoKinesis (Dock) class B proteins; Dock-B is one of 4 classes of Dock family proteins. The members here include: Dock3/MOCA (modifier of cell adhesion) and Dock4. Most of these members have been shown to be GEFs specific for Rac, although Dock4 has also been shown to interact indirectly with the Ras family GTPase Rap1, probably through Rap regulatory proteins. In addition to the C2 domain (AKA Dock homology region (DHR)-1, CED-5, Dock180, MBC-zizimin homology (CZH) 1) and the DHR-2 (AKA CZH2, or Docker), which all Dock180-related proteins have, Dock-B members contain a SH3 domain upstream of the C2 domain and a proline-rich region downstream. DHR-2 has the catalytic activity for Rac and/or Cdc42, but is structurally unrelated to the DH domain. The C2/DHR-1 domains of Dock180 and Dock4 have been shown to bind phosphatidylinositol-3, 4, 5-triphosphate (PtdIns(3,4,5)P3). The C2 domain was first identified in PKC.
