Description
Description: Required for both basal and inducible autophagy. Determines the localization of the autophagy-specific PI3-kinase complex PI3KC3-C1 (PubMed:18843052, PubMed:19050071). Plays a role in autophagosome formation and MAP1LC3/LC3 conjugation to phosphatidylethanolamine (PubMed:19270696, PubMed:20713597). Promotes BECN1 translocation from the trans-Golgi network to autophagosomes (PubMed:20713597). Enhances PIK3C3 activity in a BECN1-dependent manner. Essential for the autophagy-dependent phosphorylation of BECN1 (PubMed:23878393). Stimulates the phosphorylation of BECN1, but suppresses the phosphorylation PIK3C3 by AMPK (PubMed:23878393). Binds to STX17-SNAP29 binary t-SNARE complex on autophagosomes and primes it for VAMP8 interaction to promote autophagosome-endolysosome fusion (PubMed:25686604). Modulates the hepatic lipid metabolism (By similarity).
Subunit Structure: Forms homooligomers; homo-oligomerization is essential for the roles in membrane tethering and enhancement of SNARE-mediated fusion (PubMed:25686604). Component of the PI3K (PI3KC3/PI3K-III/class III phosphatidylinositol 3-kinase) complex I (PI3KC3-C1) in which the core composed of the catalytic subunit PIK3C3, the regulatory subunit PIK3R4 and BECN1 is associated with ATG14 (PubMed:18843052, PubMed:19050071, PubMed:19270696, PubMed:22314358, PubMed:23878393). PI3KC3-C1 displays a V-shaped architecture with PIK3R4 serving as a bridge between PIK3C3 and the ATG14:BECN1 subcomplex (PubMed:25490155). PI3KC3-C1 can associate with further regulatory subunits. Interacts with PIK3CB (By similarity). Interacts (via coiled-coil domain) with BECN2 (via coiled-coil domain); this interaction is tighter than BECN2 self-association (PubMed:23954414, PubMed:28218432). Interacts with the STX17-SNAP29 binary t-SNARE complex (PubMed:25686604). Interacts with NRBF2 (By similarity).
Similarity: The coiled-coil domain is required for BECN1- and PIK3C3-binding and for autophagy. The final 80 residues in the C-terminus define a minimum required region for autophagosome binding called BATS. The N-terminal cysteine repeats are required for proper localization to the endoplasmic reticulum. Belongs to the ATG14 family
