Calmodulin mediates the control of a large number of enzymes, ion channels and other proteins by Ca(2+). Among the enzymes to be stimulated by the calmodulin-Ca(2+) complex are a number of protein kinases and phosphatases. Component of the spindle pole body (SPB) required for the proper execution of spindle pole body (SPB) duplication. Component of the SPC110 complex containing at least CMD1, SPC29, SPC42 and SCP110. Interacts with SPC110. The N-terminus is blocked. This protein has three functional calcium-binding sites. Belongs to the calmodulin family.
