GeneCards Summary for PPP4R3A Gene

PPP4R3A (Protein Phosphatase 4 Regulatory Subunit 3A) is a Protein Coding gene. Among its related pathways are Integrated Breast Cancer Pathway and Glucagon signaling pathway. An important paralog of this gene is PPP4R3B.

UniProtKB/Swiss-Prot for PPP4R3A Gene

  • Regulatory subunit of serine/threonine-protein phosphatase 4. May regulate the activity of PPP4C at centrosomal microtubule organizing centers. The PPP4C-PPP4R2-PPP4R3A PP4 complex specifically dephosphorylates H2AFX phosphorylated on Ser-140 (gamma-H2AFX) generated during DNA replication and required for DNA DSB repair.
