PPP3CA (Protein Phosphatase 3 Catalytic Subunit Alpha): PPP3CA is a gene that codes for the catalytic subunit alpha of protein phosphatase 3 (PP3), also known as calcineurin. Calcineurin is a calcium-dependent phosphatase involved in signaling pathways that regulate immune responses and cellular processes such as gene expression. PPP3CA's activity contributes to the dephosphorylation of target proteins, influencing multiple cellular functions....
