Cell-permeable calmodulin (CaM) agonist that binds to the EF-hand/Ca2+-binding site. Activates phosphodiesterase in the absence of Ca2+ and inhibits Ca2+-mediated cytotoxicity and apoptosis (IC50 = 33 μM).
CALP3 TFA is a potent Ca2+ channel blocker that activates EF-hand motifs of Ca2+-binding proteins. It can functionally mimic increased [Ca2+]i by modulating the activity of Calmodulin, Ca2+ channels, and pumps.
