CC -!- FUNCTION: Calmodulin mediates the control of a large number of enzymes,
CC ion channels and other proteins by Ca(2+). Among the enzymes to be
CC stimulated by the calmodulin-Ca(2+) complex are a number of protein
CC kinases and phosphatases.
CC -!- MISCELLANEOUS: This protein has four functional calcium-binding sites.
CC -!- SIMILARITY: Belongs to the calmodulin family. {ECO:0000305}.
