Enzyme Function FUNCTION: Gag polyprotein plays a role in budding and is processed by the viral protease during virion maturation outside the cell. During budding, it recruits, in a PPXY-dependent or independent manner, Nedd4-like ubiquitin ligases that conjugate ubiquitin molecules to Gag, or to Gag binding host factors. Interaction with HECT ubiquitin ligases probably link the viral protein to the host ESCRT pathway and facilitate release (By similarity). {ECO:0000250}.; FUNCTION: Matrix protein p15 targets Gag and gag-pol polyproteins to the plasma membrane via a multipartite membrane binding signal, that includes its myristoylated N-terminus. Also mediates nuclear localization of the preintegration complex (By similarity). {ECO:0000250}.; FUNCTION: Capsid protein p30 forms the spherical core of the virion that encapsulates the genomic RNA-nucleocapsid complex. {ECO:0000250}.

Modified Residue
Post Translational Modification PTM: Specific enzymatic cleavages by the viral protease yield mature proteins. The protease is released by autocatalytic cleavage. The polyprotein is cleaved during and after budding, this process is termed maturation (By similarity). {ECO:0000250}.
