Calmodulin 2, 1-149aa, Human, Recombinant, E.coli

Calmodulin has been known to act as an intracellular calcium sensor protein. When the intracellular Ca2+ concentration increases, calmodulin can bind up to four Ca2+, changing its conformation and regulating cellular functions such as activation or inhibition of a large number of enzymes, ion channels, and receptors.
