Contributes to calcium-dependent protein serine/threonine phosphatase activity. Involved in several processes, including cellular response to pheromone; conjugation with cellular fusion; and fungal-type cell wall organization. Part of calcineurin complex. Human ortholog(s) of this gene implicated in aortic valve stenosis; developmental and epileptic encephalopathy 91; and schizophrenia. Orthologous to human PPP3CA (protein phosphatase 3 catalytic subunit alpha); PPP3CB (protein phosphatase 3 catalytic subunit beta); and PPP3CC (protein phosphatase 3 catalytic subunit gamma).
SGD Description
Calcineurin A; one isoform (the other is Cmp2p) of the catalytic subunit of calcineurin, a Ca++/calmodulin-regulated protein phosphatase which regulates Crz1p (a stress-response transcription factor), the other calcineurin subunit is CNB1; regulates the function of Aly1p alpha-arrestin; CNA1 has a paralog, CMP2, that arose from the whole genome duplication
