Purity > 90% as determined by SDS-PAGE. MW: 18.7kDa. Full Length of Mature Protein: 2-149aa. N-terminal 6xHis-tagged. Homo sapiens (Human). Calmodulin mediates the control of a large number of enzymes, ion channels, aquaporins and other proteins by Ca2+. Among the enzymes to be stimulated by the calmodulin-Ca2+ complex are a number of protein kinases and phosphatases. Together with CCP110 and centrin, is involved in a genetic pathway that regulates the centrosome cycle and progression through cytokinesis.
