| Enzyme Function | FUNCTION: Matrix protein p17 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. Implicated in the release from host cell mediated by Vpu (By similarity). {ECO:0000250}.; FUNCTION: Capsid protein p24 forms the conical core of the virus that encapsulates the genomic RNA-nucleocapsid complex. {ECO:0000250}.; FUNCTION: Nucleocapsid protein p7 encapsulates and protects viral dimeric unspliced (genomic) RNA. Binds these RNAs through its zinc fingers (By similarity). {ECO:0000250}.; FUNCTION: p6-gag plays a role in budding of the assembled particle by interacting with the host class E VPS proteins TSG101 and PDCD6IP/AIP1. {ECO:0000250}. |

| Subcellular Location | SUBCELLULAR LOCATION: [Matrix protein p17]: Virion {ECO:0000305}. Host nucleus {ECO:0000250}. Host cytoplasm {ECO:0000250}. Note=Following virus entry, the nuclear localization signal (NLS) of the matrix protein participates with Vpr to the nuclear localization of the viral genome. During virus production, the nuclear export activity of the matrix protein counteracts the NLS to maintain the Gag and Gag-Pol polyproteins in the cytoplasm, thereby directing unspliced RNA to the plasma membrane (By similarity). {ECO:0000250}.; SUBCELLULAR LOCATION: [Capsid protein p24]: Virion {ECO:0000305}.; SUBCELLULAR LOCATION: [Nucleocapsid protein p7]: Virion {ECO:0000305}. |
| Modified Residue | |
| Post Translational Modification | PTM: Capsid protein p24 is phosphorylated. {ECO:0000250}.; PTM: Specific enzymatic cleavages by the viral protease yield mature proteins. The polyprotein is cleaved during and after budding, this process is termed maturation (By similarity). {ECO:0000250}. |
