Calmodulin--an intracellular calcium receptor.


PMID 6990273

Abstract

Calmodulin, a protein that binds calcium with high affinity and specificity, is structurally conserved and functionally preserved throughout the animal and plant kingdoms. It serves as an intracellular Ca2+-receptor and mediates the Ca2+ regulation of cyclic nucleotide and glycogen metabolism, secretion, motility and Ca2+ transport. Calmodulin is also a dynamic component of the mitotic apparatus.
