Affinity Capture-Western

An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner identified by Western blot with a specific polyclonal antibody or second epitope tag. This category is also used if an interacting protein is visualized directly by dye stain or radioactivity. Note that this differs from any co-purification experiment involving affinity capture in that the co-purification experiment involves at least one extra purification step to get rid of potential contaminating proteins.

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

Strack B, Calistri A, Craig S, Popova E, Goettlinger HG

HIV-1 and other retroviruses exit infected cells by budding from the plasma membrane, a process requiring membrane fission. The primary late assembly (L) domain in the p6 region of HIV-1 Gag mediates the detachment of the virion by recruiting host Tsg101, a component of the class E vacuolar protein sorting (Vps) machinery. We now show that HIV Gag p6 contains ... [more]
