Pleckstrin homology-like domain, family A, member 3; p53/TP53-regulated repressor of Akt/AKT1 signaling. Represses AKT1 by preventing AKT1-binding to membrane lipids, thereby inhibiting AKT1 translocation to the cellular membrane and activation. Contributes to p53/TP53-dependent apoptosis by repressing AKT1 activity. Its direct transcription regulation by p53/TP53 may explain how p53/TP53 can negatively regulate AKT1. May act as a tumor suppressor; Belongs to the PHLDA3 family.
Synonyms: PHLDA3, PHLDA3p, hPHLDA3, Q9Y5J5, Q9Y5J5p ...
