AIP1/ALIX is a binding partner for HIV-1 p6 and EIAV p9 functioning in virus budding

Article Abstract:

Results indicate that AIP1, also known as ALIX, couples HIV-1 Gag p6 and EIAV p9 to the endosomal sorting complex. Data suggest that AIP1 is a component of the viral budding machinery linking the late assembly L domain of HIV-1 Gag p6 and EIAV P9 to the sorting complex. These processes facilitate retroviruses exit from the infected cells by budding from the plasma membrane.

Species-specific exclusion of APOBEC3G from HIV-1 virions by Vif

Article Abstract:

Research describes the formation of a complex between HIV-1 virion infectivity factor, Vif, and the human APOBEC3G, a virion-encapasidated cellular protein that is involved in the deamination of the minus-strand reverse transcript cytosines to uracils, which prevents its virion encapasidation. However, mouse APOBEC3G cannot catalyze encapasidation.

The protein network of HIV budding

Article Abstract:

Research demonstrates that 22 class E proteins along with a protein network consisting of 43 other protein-protein complexes mediate human multivesicular bodies biogenesis as well as participate in the release of HIV and other viruses by budding. Data indicate that AIP1 plays a key role in this viral budding process.
