C2Protein kinase C conserved region 2 (CalB)
|SMART accession number:||SM00239|
|Description:||Ca2+-binding motif present in phospholipases, protein kinases C, and synaptotagmins (among others). Some do not appear to contain Ca2+-binding sites. Particular C2s appear to bind phospholipids, inositol polyphosphates, and intracellular proteins. Unusual occurrence in perforin. Synaptotagmin and PLC C2s are permuted in sequence with respect to N- and C-terminal beta strands. SMART detects C2 domains using one or both of two profiles.|
|Interpro abstract (IPR000008):||The C2 domain is a Ca2+-dependent membrane-targeting module found in many cellular proteins involved in signal transduction or membrane trafficking. C2 domains are unique among membrane targeting domains in that they show wide range of lipid selectivity for the major components of cell membranes, including phosphatidylserine and phosphatidylcholine. This C2 domain is about 116 amino-acid residues and is located between the two copies of the C1 domain in Protein Kinase C (that bind phorbol esters and diacylglycerol) and the protein kinase catalytic domain . Regions with significant homology [(PUBMED:7559667)] to the C2-domain have been found in many proteins. The C2 domain is thought to be involved in calcium-dependent phospholipid binding [(PUBMED:8253763)] and in membrane targetting processes such as subcellular localisation. |
The 3D structure of the C2 domain of synaptotagmin has been reported [(PUBMED:7697723)], the domain forms an eight-stranded beta sandwich constructed around a conserved 4-stranded motif, designated a C2 key [(PUBMED:7697723)]. Calcium binds in a cup-shaped depression formed by the N- and C-terminal loops of the C2-key motif. Structural analyses of several C2 domains have shown them to consist of similar ternary structures in which three Ca2+-binding loops are located at the end of an 8 stranded antiparallel beta sandwich.

C1 domains are compact alpha/beta structural units of about 50 amino acids which tightly bind two zinc ions. These domains were first discovered as the loci of phorbol ester and diacylglycerol binding to conventional protein kinase C isozymes, which contain 2 C1 domains (C1A and C1B) in their N-terminal regulatory regions. We present a comprehensive list of 54 C1 domains occurring singly or doubly in 34 different proteins. Many C1 domains and C1 domain-containing proteins bind phorbol esters, but many others do not. By combining analysis of 54 C1 domain sequences with information from previously reported solution and crystal structure determinations and site-directed mutagenesis, profiles are derived and used to classify C1 domains. Twenty-six C1 domains fit the profile for phorbol-ester binding and are termed "typical." Twenty-eight other domains fit the profile for the overall C1 domain fold but do not fit the profile for phorbol ester binding, and are termed "atypical." Proteins containing typical C1 domains are predicted to be regulated by diacylglycerol, whereas those containing only atypical domains are not.

- Display abstract
The atypical protein kinase C (PKC) member PKC-zeta has been implicated in several signal transduction pathways regulating differentiation, proliferation or apoptosis of mammalian cells. We report here the identification of a cytoplasmic and membrane-associated protein that we name zeta-interacting protein (ZIP) and that interacts with the regulatory domain of PKC-zeta but not classic PKCs. The structural motifs in ZIP include a recently defined ZZ zinc finger as a potential protein binding module, two PEST sequences and a novel putative protein binding motif with the consensus sequence YXDEDX5SDEE/D. ZIP binds to the pseudosubstrate region in the regulatory domain of PKC-zeta and is phosphorylated by PKC-zeta in vitro. ZIP dimerizes via the same region that promotes binding to PKC-zeta suggesting a competitive situation between ZIP:ZIP and ZIP:PKC-zeta complexes. In the absence of PKC-zeta proper subcellular localization of ZIP is impaired and we show that intracellular targeting of ZIP is dependent on a balanced interaction with PKC-zeta. Taking into account the recent isolation of ZIP by others in different contexts we propose that ZIP may function as a scaffold protein linking PKC-zeta to protein tyrosine kinases and cytokine receptors.

- The C2 domain calcium-binding motif: structural and functional diversity.
- Protein Sci. 1996; 5: 2375-90
- Display abstract
The C2 domain is a Ca(2+)-binding motif of approximately 130 residues in length originally identified in the Ca(2+)-dependent isoforms of protein kinase C. Single and multiple copies of C2 domains have been identified in a growing number of eukaryotic signalling proteins that interact with cellular membranes and mediate a broad array of critical intracellular processes, including membrane trafficking, the generation of lipid-second messengers, activation of GTPases, and the control of protein phosphorylation. As a group, C2 domains display the remarkable property of binding a variety of different ligands and substrates, including Ca2+, phospholipids, inositol polyphosphates, and intracellular proteins. Expanding this functional diversity is the fact that not all proteins containing C2 domains are regulated by Ca2+, suggesting that some C2 domains may play a purely structural role or may have lost the ability to bind Ca2+. The present review summarizes the information currently available regarding the structure and function of the C2 domain and provides a novel sequence alignment of 65 C2 domain primary structures. This alignment predicts that C2 domains form two distinct topological folds, illustrated by the recent crystal structures of C2 domains from synaptotagmin 1 and phosphoinositide-specific phospholipase C-delta 1, respectively. The alignment highlights residues that may be critical to the C2 domain fold or required for Ca2+ binding and regulation.

Various membrane lipid metabolites, generated by phospholipases C and D (PLCs, PLDs), are known to regulate the activities of protein kinases C (PKCs) and GTP-ase activating proteins (GAPs) in a range of cellular processes. Conventional Ca(2+)-dependent PKCs (alpha, beta I, beta II, and gamma), PLCs and various GAPs are all known to contain copies of a phospholipid-binding domain, termed C2 or CalB. Here we recognize that C2 domains are also present in "new" Ca(2+)-independent PKCs (delta, epsilon, eta, and theta), other kinases, a eukaryotic PLD, the breakpoint cluster region (BCR) gene product, and two further GAPS. Twenty-two previously unrecognized C2 domain sequences are presented, which include a single copy in the mammalian poreforming proteins, perforin.

C2 domains are found in many proteins involved in membrane traffic or signal transduction. Although C2 domains are thought to bind calcium ions, the structural basis for calcium binding is unclear. Analysis of calcium binding to C2 domains of synaptotagmin I and protein kinase C-beta by nuclear magnetic resonance spectroscopy revealed a bipartite calcium-binding motif that involves the coordination of two calcium ions by five aspartate residues located on two separate loops. Sequence comparisons indicated that this may be a widely used calcium-binding motif, designated here as the C2 motif.

Synaptotagmins (Syts) are brain-specific Ca2+/phospholipid-binding proteins. In hippocampal synapses, Syt I is essential for fast Ca(2+)-dependent synaptic vesicle exocytosis but not for Ca(2+)-independent exocytosis. In vertebrates and invertebrates, Syt may therefore participate in Ca(2+)-dependent synaptic membrane fusion, either by serving as the Ca2+ sensor in the last step of fast Ca(2+)-triggered neurotransmitter release, or by collaborating with an additional Ca2+ sensor. While Syt I binds Ca2+ (refs 10, 11), its phospholipid binding is triggered at lower calcium concentrations (EC50 = 3-6 microM) than those required for exocytosis. Furthermore, Syts bind clathrin-AP2 with high affinity, indicating that they may play a general role in endocytosis rather than being confined to a specialized function in regulated exocytosis. Here we resolve this apparent contradiction by describing four Syts, three of which (Syt VI, VII and VIII) are widely expressed in non-neural tissues. All Syts tested share a common domain structure, with a cytoplasmic region composed of two C2 domains that interacts with clathrin-AP2 (Kd = 0.1-1.0 nM) and with neural and non-neural syntaxins. The first C2 domains of Syt I, II, III, V and VII, but not of IV, VI or VIII, bind phospholipids with a similar Ca(2+)-concentration dependence (EC50 = 3-6 microM). The same C2 domains also bind syntaxin as a function of Ca2+ but the Ca(2+)-concentration dependence of Syt I, II and V (> 200 microM) differs from that of Syt III and VII (< 10 microM).(ABSTRACT TRUNCATED AT 250 WORDS)

C2 domains are regulatory sequence motifs that occur widely in nature. Synaptotagmin I, a synaptic vesicle protein involved in the Ca2+ regulation of exocytosis, contains two C2 domains, the first of which acts as a Ca2+ sensor. We now describe the three-dimensional structure of this C2 domain at 1.9 A resolution in both the Ca(2+)-bound and Ca(2+)-free forms. The C2 polypeptide forms an eight-stranded beta sandwich constructed around a conserved four-stranded motif designated as a C2 key. Ca2+ binds in a cup-shaped depression between two polypeptide loops located at the N- and C-termini of the C2-key motif.

Neurons release neurotransmitters by calcium-dependent exocytosis of synaptic vesicles. However, the molecular steps transducing the calcium signal into membrane fusion are still an enigma. It is reported here that synaptotagmin, a highly conserved synaptic vesicle protein, binds calcium at physiological concentrations in a complex with negatively charged phospholipids. This binding is specific for calcium and involves the cytoplasmic domain of synaptotagmin. Calcium binding is dependent on the intact oligomeric structure of synaptotagmin (it is abolished by proteolytic cleavage at a single site). These results suggest that synaptotagmin acts as a cooperative calcium receptor in exocytosis.

- Phospholipid binding by a synaptic vesicle protein homologous to the regulatory region of protein kinase C.
- Nature. 1990; 345: 260-3
- Display abstract
Neurotransmitters are released at synapses by the Ca2(+)-regulated exocytosis of synaptic vesicles, which are specialized secretory organelles that store high concentrations of neurotransmitters. The rapid Ca2(+)-triggered fusion of synaptic vesicles is presumably mediated by specific proteins that must interact with Ca2+ and the phospholipid bilayer. We now report that the cytoplasmic domain of p65, a synaptic vesicle-specific protein that binds calmodulin contains an internally repeated sequence that is homologous to the regulatory C2-region of protein kinase C (PKC). The cytoplasmic domain of recombinant p65 binds acidic phospholipids with a specificity indicating an interaction of p65 with the hydrophobic core as well as the headgroups of the phospholipids. The binding specificity resembles PKC, except that p65 also binds calmodulin, placing the C2-regions in a context of potential Ca2(+)-regulation that is different from PKC. This is a novel homology between a cellular protein and the regulatory domain of protein kinase C. The structure and properties of p65 suggest that it may have a role in mediating membrane interactions during synaptic vesicle exocytosis.
