>gnl|CDD|176076 cd08694, C2_Dock-A, 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.
