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. Recombinant human Calmodulin was expressed in E. coli and purified by conventional chromatography techniques. Alternative Names: PHKD protein, Calmodulin 2 protein, LP7057 protein protein, Calmodulin -2 protein, Calmodulin 2, CAMII protein, CAM II protein, Calmodulin 2 protein, Phosphorylase kinase delta protein, PHKD2 protein, Calmodulin 2, CALM 2 protein, Calmodulin2 protein, Calmodulin -2, PHKD 2 protein, Calmodulin-2
