DESCRIPTION

Also known as STX17_HUMAN, STX17. SNAREs, soluble N-ethylmaleimide-sensitive factor-attachment protein receptors, are essential proteins for fusion of cellular membranes. SNAREs localized on opposing membranes assemble to form a trans-SNARE complex, an extended, parallel four alpha-helical bundle that drives membrane fusion (PubMed:23217709, PubMed:25686604, PubMed:28306502). STX17 is a SNARE of the autophagosome involved in autophagy through the direct control of autophagosome membrane fusion with the lysosome membrane (PubMed:23217709, PubMed:25686604, PubMed:28306502). May also play a role in the early secretory pathway where it may maintain the architecture of the endoplasmic reticulum-Golgi intermediate compartment/ERGIC and Golgi and/or regulate transport between the endoplasmic reticulum, the ERGIC and the Golgi (PubMed:21545355). Forms a SNARE complex composed of VAMP8, SNAP29 and STX17 involved in fusion of autophagosome with lysosome (PubMed:23217709, PubMed:25686604). Interacts with VAMP7 and VTI1B (PubMed:23217709). Probably interacts with BET1, SCFD1 and SEC22B (By similarity). Interacts with PTPN2 and ABL1; involved in STX17 phosphorylation (PubMed:23006999). Interacts with COPB1 (By similarity). Interacts with TMED9 and TMED10; the interaction is direct (PubMed:21545355). Interacts with ATG14 (PubMed:25686604). Interacts with RUBCNL/PACER; promoting targeting of RUBCNL/PACER to autophagosome (PubMed:28306502, PubMed:30704899). Interacts with VAMP8, SNAP29, VPS39 and VPS41; these interactions are increased in the absence of TMEM39A (PubMed:31806350, PubMed:33422265).
