WB Use a concentration of 0.2 - 1 µg/ml. Detects a band of approximately 18 kDa (predicted molecular weight: 14 kDa).


  • Functionp53/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 directs transcription regulation by p53/TP53 may explain how p53/TP53 can negatively regulate AKT1. May acts as a tumor suppressor.
  • Tissue specificityWidely expressed with lowest expression in liver and spleen.
  • Sequence similaritiesBelongs to the PHLDA3 family.
    Contains 1 PH domain.
  • DomainThe PH domain binds phosphoinositides with a broad specificity. It competes with the PH domain of AKT1 and directly interferes with AKT1 binding to phosphatidylinositol 4,5-bisphosphate (PIP2) and phosphatidylinositol 3,4,5-triphosphate (PIP3), preventing AKT1 association to membrane lipids and subsequent activation of AKT1 signaling.
