PPP3CA Antibody – Rabbit Polyclonal

PPP3CA: a calmodulin-dependent Ser/Thr phosphatase also known calcineurin A alpha. Involved in a wide range of biologic activities, acting as a Ca(2 )-dependent modifier of phosphorylation status. Dephosphorylates HSPB1. The calcineurin holoenzyme is composed of catalytic and regulatory subunits of 60 and 18 kD, respectively. .
