Plays a central role in autophagy. Required for the abcission step in cytokinesis. May play a role in antiviral host defense.
Specificity
Natural and recombinant Mouse Beclin-1
Subcellular Location
Cytoplasm Golgi apparatus trans-Golgi network membrane Peripheral membrane protein Interaction with ATG14 promotes translocation to autophagosomes (By similarity). Expressed in dendrites and cell bodies of cerebellar Purkinje cells.
Interacts with BCL2 and BCL2L1 (By similarity). Interacts with GOPC and GRID2. Interacts with AMBRA1. Forms a complex with PIK3C3 and PIK3R4 and either UVRAG and Rubicon, or with ATG14. UVRAG and ATG14 form mutually exclusive complexes through direct competition for BECN1-binding. The complex containing ATG14 upregulates autophagy, while the one containing Rubicon downregulates autophagy. Interacts with VMP1 (By similarity). Interacts with PIK3CB.
