SNX1

Intracellular

Cell type enhanced (Oligodendrocytes)

Low immune cell specificity

Low cell line specificity

Predominantly forms heterodimers with BAR domain-containing sorting nexins SNX5, SNX6 and SNX32; can self-associate to form homodimers (PubMed:23085988). The heterodimers are proposed to self-assemble into helical arrays on the membrane to stabilize and expand local membrane curvature underlying endosomal tubule formation. Thought to be a component of the originally described retromer complex (also called SNX-BAR retromer) which is a pentamer containing the heterotrimeric retromer cargo-selective complex (CSC), also described as vacuolar protein sorting subcomplex (VPS) and a heterodimeric membrane-deforming subcomplex formed between SNX1 or SNX2 and SNX5 or SNX6 (also called SNX-BAR subcomplex); the respective CSC and SNX-BAR subcomplexes associate with low affinity (Probable). Interacts with SNX5, SNX6, SNX32, VPS26A, VPS29, VPS35, DRD5, DENND5A, KALRN, RHOG (GDP-bound form) (PubMed:9819414, PubMed:11102511, PubMed:19619496, PubMed:19935774, PubMed:19619496, PubMed:20604901, PubMed:23085988, PubMed:23152498). The interaction with SNX2 is reported controversially (PubMed:9819414, PubMed:11997453, PubMed:19619496, PubMed:23085988). Interacts with DNAJC13; prevented by presence of HGS (PubMed:19874558). Interacts with HGS (By similarity).
