PPP2R3C (Protein Phosphatase 2 Regulatory Subunit B''Gamma): PPP2R3C is a gene that encodes a regulatory subunit of the protein phosphatase 2 (PP2A) complex. PP2A is a serine/threonine phosphatase involved in regulating cell growth and division. PPP2R3C modulates PP2A activity, impacting key signaling pathways related to cellular stress responses, DNA damage repair, and apoptosis. Its function is crucial for maintaining cellular homeostasis and controlling cell cycle checkpoints.
