Many other proteins will bind calcium, although the binding site usually has considerable homology with the calcium-binding domains of calmodulin. They can act as transport proteins, regulator proteins or activator proteins. There is also a vitamin D-dependent variant which is a protein that plays a fundamental role in the vitamin d mediated transport of calcium in reptiles, amphibians, birds and mammals. It is found in the intestine, kidneys, egg shell gland, brain, and possibly other organs. Its molecular weight is species dependent. (12 May 2002) |

| protein kinase C |
any of a family of protein kinase isozymes, occurring in numerous tissues, that catalyze the phosphorylation of specific serine or threonine residues of a variety of intracellular proteins, altering their activities. The enzymes are activated via receptor binding by the hormones, growth factors, and other agents that cause increases in intracellular calcium and cleavage of phosphoinositides; some isozymes require calcium and phospholipid for activity, which is enhanced by diacylglycerol. ...
