This gene encodes an
apoptosis
Apoptosis (from grc, ἀπόπτωσις, apóptōsis, 'falling off') is a form of programmed cell death that occurs in multicellular organisms. Biochemical events lead to characteristic cell changes (morphology) and death. These changes incl ...

growth factor deprivation. This protein suppresses the
transcription factor E2F1-induced apoptosis and also interacts with, and negatively regulates acinus, a
