Apoptosis-stimulating of p53 protein 1 is a protein that in humans is encoded by the PPP1R13B gene.This gene encodes a member of the ASPP (apoptosis-stimulating protein of p53) family of p53 interacting proteins. The protein contains four ankyrin repeats and an SH3 domain involved in protein-protein interactions. ASPP proteins are required for the induction of apoptosis by p53-family proteins.
