C2 Domain
A C2 domain is a protein structural domain involved in targeting proteins to cell membranes. The typical version (PKC-C2) has a beta-sandwich composed of 8 beta sheet, β-strands that co-ordinates two or three calcium ions, which bind in a cavity formed by the first and final loops of the domain, on the membrane binding face. Many other C2 domain families don't have calcium binding activity. Coupling with other domains C2 domains are frequently found coupled to enzyme, enzymatic domains; for example, the C2 domain in PTEN (gene), PTEN, brings the phosphatase domain into contact with the plasma membrane, where it can dephosphorylate its substrate, Phosphatidylinositol (3,4,5)-trisphosphate, phosphatidylinositol (3,4,5)-trisphosphate (PIP3), without removing it from the membrane - which would be energetically very costly. PTEN consists of two domains, a protein tyrosine phosphatase domain and a C2 domain. This domain pair constitutes a superdomain, a heritable unit that is found in ...

Calcium
Calcium is a chemical element with the symbol Ca and atomic number 20. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air. Its physical and chemical properties are most similar to its heavier homologues strontium and barium. It is the fifth most abundant element in Earth's crust, and the third most abundant metal, after iron and aluminium. The most common calcium compound on Earth is calcium carbonate, found in limestone and the fossilised remnants of early sea life; gypsum, anhydrite, fluorite, and apatite are also sources of calcium. The name derives from Latin ''calx'' "lime", which was obtained from heating limestone. Some calcium compounds were known to the ancients, though their chemistry was unknown until the seventeenth century. Pure calcium was isolated in 1808 via electrolysis of its oxide by Humphry Davy, who named the element. Calcium compounds are widely used in many industries: in foods and pharma ...

Clostridium Perfringens Alpha Toxin
''Clostridium perfringens'' alpha toxin is a toxin produced by the bacterium ''Clostridium perfringens'' (''C. perfringens'') and is responsible for gas gangrene and myonecrosis in infected tissues. The toxin also possesses hemolytic activity. Clinical significance This toxin has been shown to be the key virulence factor in infection with ''C. perfringens''; the bacterium is unable to cause disease without this toxin. Further, vaccination against the alpha toxin toxoid protects mice against ''C. perfringens'' gas gangrene. As a result, knowledge about the function of this particular protein greatly aids understanding of myonecrosis. Structure and homology The alpha toxin has remarkable similarity to toxins produced by other bacteria as well as natural enzymes. There is significant homology with phospholipase C enzymes from ''Bacillus cereus'', ''C. bifermentans'', and ''Listeria monocytogenes''. The C terminal domain shows similarity with non-bacterial enzymes such as pancreati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

CAPN6
Calpain-6 (also known as calpamodulin) is a protein in humans that is encoded by the ''CAPN6'' gene. Calpains are a ubiquitous, well-conserved family of calcium-dependent, cysteine proteases. In the MEROPS protease enzyme classification system, they are members of clan CA (papain-like proteases). The calpain proteins are heterodimers consisting of an invariant small subunit and variable large subunits. The large subunit possesses a cysteine protease domain, and both subunits possess calcium-binding domains. Calpains have been implicated in neurodegenerative processes, as their activation can be triggered by calcium influx and oxidative stress. The protein encoded by this gene is highly expressed in the placenta. Its C-terminal region lacks any homology to the calmodulin-like domain of other calpains. The protein lacks a critical catalytic triad residue in its active site (cysteine nucleophile mutated to lysine) and thus is suggested to be proteolytically inactive. The protein may ...

CAPN5
Calpain-5 is a protein that in humans is encoded by the ''CAPN5'' gene. Calpains are calcium-dependent cysteine proteases involved in signal transduction in a variety of cellular processes. A functional calpain protein consists of an invariant small subunit and 1 of a family of large subunits. CAPN5 is one of the large subunits. Unlike some of the calpains, CAPN5 and CAPN6 lack a calmodulin-like domain IV. Because of the significant similarity to Caenorhabditis elegans sex determination gene tra-3, CAPN5 is also called as HTRA3.

CADPS2
Calcium-dependent secretion activator 2 is a protein that in humans is encoded by the ''CADPS2'' gene. Function This gene encodes a member of the calcium-dependent activator of secretion (CAPS) protein family, which are calcium-binding proteins that regulate the exocytosis of synaptic and dense-core vesicles in neurons and neuroendocrine cells. Interactions This gene interacts with brain-derived neurotrophic factor. Clinical significance Cadps2 has been linked to autism and is in the 7q autism susceptibility locus (AUTS1). However, the finding of aberrant CADPS2 splicing was not found to be significant in another study.

CADPS
Calcium-dependent secretion activator 1 is a protein that in humans is encoded by the ''CADPS'' gene. CADPS encodes a novel neural/ endocrine-specific cytosolic and peripheral membrane protein required for the Ca2+-regulated exocytosis of secretory vesicles. CADPS acts at a stage in exocytosis that follows ATP-dependent priming, which involves the essential synthesis of phosphatidylinositol 4,5-bisphosphate Phosphatidylinositol 4,5-bisphosphate or PtdIns(4,5)''P''2, also known simply as PIP2 or PI(4,5)P2, is a minor phospholipid component of cell membranes. PtdIns(4,5)''P''2 is enriched at the plasma membrane where it is a substrate for a number o ... (PtdIns(4,5)P2).

C2CD3
C, or c, is the third letter in the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''cee'' (pronounced ), plural ''cees''. History "C" comes from the same letter as "G". The Semites named it gimel. The sign is possibly adapted from an Egyptian hieroglyph for a staff sling, which may have been the meaning of the name ''gimel''. Another possibility is that it depicted a camel, the Semitic name for which was ''gamal''. Barry B. Powell, a specialist in the history of writing, states "It is hard to imagine how gimel = "camel" can be derived from the picture of a camel (it may show his hump, or his head and neck!)". In the Etruscan language, plosive consonants had no contrastive voicing, so the Greek ' Γ' (Gamma) was adopted into the Etruscan alphabet to represent .

BCR Gene
The breakpoint cluster region protein (BCR) also known as renal carcinoma antigen NY-REN-26 is a protein that in humans is encoded by the ''BCR'' gene. ''BCR'' is one of the two genes in the ''BCR-ABL'' fusion protein, which is associated with the Philadelphia chromosome. Two transcript variants encoding different isoforms have been found for this gene. Function Although the BCR- ABL fusion protein has been much studied, the function of the normal BCR gene product is still not clear. The protein has serine/threonine kinase activity and is a guanine nucleotide exchange factor for the Rho family of GTPases including RhoA. Clinical significance A reciprocal translocation between chromosomes 22 and 9 produces the Philadelphia chromosome, which is often found in patients with chronic myelogenous leukemia. The chromosome 22 breakpoint for this translocation is located within the ''BCR'' gene. The translocation produces a fusion protein that is encoded by sequence from both ''BCR'' ...

BAIAP3
BAI1-associated protein 3 is a protein that in humans is encoded by the ''BAIAP3'' gene. BAIAP3 was identified as a protein-binding partner of BAI1. BAI1 is a p53-target gene that encodes a brain-specific angiogenesis inhibitor. The protein is a seven-span transmembrane protein and a member of the secretin receptor family. BAIAP3 interacts with the cytoplasmic region of brain-specific angiogenesis inhibitor 1. BAIAP3 also contains two C2 domains, which are often found in proteins involved in signal transduction or membrane trafficking. Its expression pattern and similarity to other proteins suggest that it may be involved in synaptic functions. Interactions BAIAP3 has been shown to interact with Brain-specific angiogenesis inhibitor 1 Brain-specific angiogenesis inhibitor 1 is a protein that in humans is encoded by the ''BAI1'' gene. It is a member of the adhesion-GPCR family of receptors. Function Angiogenesis is controlled by a local balance between stimulators and inh ...
