Comment typeDescription
Function Plays a central role in autophagy. Required for the abcission step in cytokinesis. May play a role in antiviral host defense. Protects against infection by a neurovirulent strain of Sindbis virus. {ECO:0000269|PubMed:20208530}.

Ptm Phosphorylation at Thr-119 by DAPK1 reduces its interaction with BCL2 and BCL2L1 and promotes induction of autophagy. {ECO:0000269|PubMed:19180116}.
Ptm polyubiquitinated by NEDD4, both with 'Lys11'- and 'Lys63'- linkages. 'Lys'-11-linked poyubiquitination leads to degradation and is enhanced when the stabilizing interaction partner VPS34 is depleted. Deubiquitinated by USP10 and USP13, leading to stabilize the PIK3C3/VPS34-containing complexes. {ECO:0000269|PubMed:21936852, ECO:0000269|PubMed:21962518}.
Similarity Belongs to the beclin family. {ECO:0000305}.
Subcellular Location Golgi apparatus, trans-Golgi network membrane {ECO:0000269|PubMed:19050071}; Peripheral membrane protein {ECO:0000269|PubMed:19050071}. Note=Interaction with ATG14 promotes translocation to autophagosomes. Expressed in dendrites and cell bodies of cerebellar Purkinje cells (By similarity). {ECO:0000250}.
Subunit Interacts with GOPC and GRID2. Interacts with AMBRA1. Forms a complex with PIK3C3 and PIK3R4 and either UVRAG and KIAA0226/Rubicon, or with ATG14. UVRAG and ATG14 form mutually exclusive complexes through direct competition for BECN1-binding. The complex containing ATG14 up-regulates autophagy, while the one containing Rubicon down-regulates autophagy (By similarity). Interacts with BCL2 and BCL2L1. Interacts with VMP1. Interacts with PIK3CB (By similarity). Interacts with DAPK1. Interacts with human cytomegalovirus/HHV-5 protein TRS1. {ECO:0000250, ECO:0000269|PubMed:17337444, ECO:0000269|PubMed:17659302, ECO:0000269|PubMed:17724469, ECO:0000269|PubMed:18843052, ECO:0000269|PubMed:19050071, ECO:0000269|PubMed:19180116, ECO:0000269|PubMed:19270696, ECO:0000269|PubMed:21962518, ECO:0000269|PubMed:22205736, ECO:0000269|PubMed:9765397}.
