Protein Information (annotations from UniProt)

Database IDHIV0006466
UniProt IDQ08209
Primary gene name(s)PPP3CA
Synonym gene name(s)CALNA, CNA
Protein nameSerine/threonine-protein phosphatase 2B catalytic subunit alpha isoform
Protein functionCalcium-dependent, calmodulin-stimulated protein phosphatase. Many of the substrates contain a PxIxIT motif. This subunit may have a role in the calmodulin activation of calcineurin. Dephosphorylates DNM1L, HSPB1 and SSH1. {ECO:0000269|PubMed:15671020, ECO:0000269|PubMed:17498738, ECO:0000269|PubMed:18838687}.
Subcellular locationCell membrane {ECO:0000250}. Cell membrane, sarcolemma {ECO:0000250}. Nucleus {ECO:0000250}. Note=Colocalizes with ACTN1 and MYOZ2 at the Z line in heart and skeletal muscle. {ECO:0000250}.
