RT "BECN2 interacts with ATG14 through a metastable coiled-coil to mediate
RT autophagy.";
RL Protein Sci. 26:972-984(2017).
CC -!- FUNCTION: Involved in 2 distinct lysosomal degradation pathways: acts
CC as a regulator of autophagy and as a regulator of G-protein coupled
CC receptors turnover. Regulates degradation in lysosomes of a variety of
CC G-protein coupled receptors via its interaction with GPRASP1/GASP1.
CC {ECO:0000269|PubMed:23954414}.
CC -!- SUBUNIT: Homodimer (via coiled-coil domain) (PubMed:28218432).
CC Interacts (via coiled-coil domain) with ATG14 (via coiled-coil domain);
CC this interaction is tighter than BECN2 self-association
CC (PubMed:23954414, PubMed:28218432). Interacts with AMBRA1, UVRAG and
CC PIK3C3/VPS34; these interactions are not disrupted by starvation
CC (PubMed:23954414). Does not interact with RUBCN (PubMed:23954414).
CC Interacts (via N-terminus) with GPRASP1/GASP1; the interaction is
CC direct (PubMed:23954414). {ECO:0000269|PubMed:23954414,
CC ECO:0000269|PubMed:28218432}.
CC -!- INTERACTION:
CC A8MW95; Q5JY77: GPRASP1; NbExp=4; IntAct=EBI-8839517, EBI-2514717;
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000305}.
CC -!- TISSUE SPECIFICITY: Present in fetal and adult brain (at protein
CC level). {ECO:0000269|PubMed:23954414}.
CC -!- SIMILARITY: Belongs to the beclin family. {ECO:0000305}.
