[[http://www.uniprot.org/uniprot/CALM1_HUMAN CALM1_HUMAN]] Calmodulin mediates the control of a large number of enzymes, ion channels, aquaporins and other proteins through calcium-binding. Among the enzymes to be stimulated by the calmodulin-calcium 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 (PubMed:16760425). Mediates calcium-dependent inactivation of CACNA1C (PubMed:26969752). Positively regulates calcium-activated potassium channel activity of KCNN2 (PubMed:27165696).<ref>PMID:16760425</ref> <ref>PMID:23893133</ref> <ref>PMID:26969752</ref> <ref>PMID:27165696</ref> [[http://www.uniprot.org/uniprot/FKB1B_HUMAN FKB1B_HUMAN]] Has the potential to contribute to the immunosuppressive and toxic effects of FK506 and rapamycin.

The high-conductance intracellular calcium (Ca(2+)) channel RyR2 is essential for the coupling of excitation and contraction in cardiac muscle. Among various modulators, calmodulin (CaM) regulates RyR2 in a Ca(2+)-dependent manner. Here we reveal the regulatory mechanism by which porcine RyR2 is modulated by human CaM through the structural determination of RyR2 under eight conditions. Apo-CaM and Ca(2+)-CaM bind to distinct but overlapping sites in an elongated cleft formed by the handle, helical and central domains. The shift in CaM-binding sites on RyR2 is controlled by Ca(2+) binding to CaM, rather than to RyR2. Ca(2+)-CaM induces rotations and intradomain shifts of individual central domains, resulting in pore closure of the PCB95 and Ca(2+)-activated channel. By contrast, the pore of the ATP, caffeine and Ca(2+)-activated channel remains open in the presence of Ca(2+)-CaM, which suggests that Ca(2+)-CaM is one of the many competing modulators of RyR2 gating.
