Forms heterodimers with BAR domain-containing sorting nexins SNX1 and SNX2; does not homodimerize (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 SNX1, SNX2, VPS26A, VPS29, VPS35, DCTN1, DOCK1, MIB1, PIP5K1C isoform 3. Interacts with HGS; increased by PIP5K1C isoform 3 kinase activity and by PtdIns(3P) and/or PtdIns(3,4)P2 (PubMed:16857196, PubMed:16968745, PubMed:19619496, PubMed:23085988, PubMed:18596235, PubMed:23602387, PubMed:24610942). (Microbial infection) Interacts with human cytomegalovirus proteins UL35 and UL35A; these interactions inhibit the ability of USP7 to form nuclear bodies.
