HIV protein: Pr55(Gag)
Interaction type: inhibited by
Description: Overexpression of the C-terminal fragment of HRS (residues 391-777) or HRS mutants lacking either the N-terminal FYVE domain (residues 215-290) or the PSAP (residues 348-351) motif efficiently inhibit HIV-1 Gag particle production

HIV protein: Vpu
Interaction type: cooperates with
Description: HRS, an ESCRT-0 complex component, is required for the Vpu-induced downregulation of BST-2, indicating that Vpu-induced BST-2 degradation involves the ESCRT/MVB pathway

HIV protein: Vpu
Interaction type: requires
Description: Physiological levels of Vpu requires the core ESCRT pathway (TSG1010 and UBAP1) and HGA (HRS) for Vpu-mediated BST-2 (tetherin) degradation but does NOT require these proteins for counteraction of BST2 (tetherin's) physical antiviral activity

HIV protein: Vpu
Interaction type: interacts with
Description: Vpu interacts with HGS (HRS) via the HGS double-ubiquitin interaction motif, indicating this motif is the direct binding site for Vpu or ubiquitination of cargo mediates Vpu/HGS interaction or by factors associated in the degradation pathway
