PPase-2B is a heterodimeric enzyme composed of a 19kDa calcium-binding subunit and a catalytic subunit (61kDa) that binds calmodulin. PPase-2B was originally identified based on its calcium- and calmodulin-dependent activity toward phosphorylase kinase and inhibitor-1. PPase-2B is identical to the brain protein calcineurin, which constitutes up to 1% of total brain protein. The immunosuppressive drugs FK-506 and cyclosporin A inhibit PPase-2B activity in immune cells, implicating a role for this enzyme in regulation of the immune system. PPase-2B also plays a major role in regulating secretory functions of a varie...
