ATG5 and BECLIN-1 belong to two kind of crucial autophagy-related proteins included the formation of autoph-agosomes,in addition to the promotion of autophagy,enhances susceptibility towards apoptotic stimuli,therefore,ATG5 and BECLIN-1 are considered to be a molecular link between autophagy and apoptosis.Preliminary data revealed that ATG5 media-ted the formation of autophagosomes by ATG5-ATG12-ATG16L ubiquitination system,while BECLIN-1 induces autophagy by phosphatidylino3-kinase (PtdIns3KC3)complex.But now it is believed that truncated ATG5(tATG5-N)and truncated BEC-LIN-1(BECLIN-1-C),an amino-terminal cleavage product of ATG5 and carboxyl-terminal cleavage product of BECLIN-1, could induce apoptosis.The research summarize the progress on ATG5 and BECLIN-1 regulated autophagy and apoptosis,so as to further reveal the molecular mechanism of they regulate autophagy and apoptosis.
