DESCRIPTION

Also known as PP2BC_HUMAN, PPP3CC, CALNA3, CNA3. Calcium-dependent, calmodulin-stimulated protein phosphatase which plays an essential role in the transduction of intracellular Ca(2+)-mediated signals. Dephosphorylates and activates transcription factor NFATC1. Dephosphorylates and inactivates transcription factor ELK1. Dephosphorylates DARPP32. Forms a complex composed of a calmodulin-dependent catalytic subunit (also known as calcineurin A) and a regulatory Ca(2+)-binding subunit (also known as calcineurin B) (PubMed:19154138). There are three catalytic subunits, each encoded by a separate gene (PPP3CA, PPP3CB, and PPP3CC) and two regulatory subunits which are also encoded by separate genes (PPP3R1 and PPP3R2). In response to an increase in Ca(2+) intracellular levels, forms a complex composed of PPP3CC/calcineurin A, calcineurin B and calmodulin (By similarity). Interacts (via calmodulin-binding domain) with calmodulin; the interaction depends on calmodulin binding to Ca(2+) (By similarity). Interacts with UNC119 (By similarity).
