Protein: Gag-Pol polyprotein (Pr180gag-pol) [Cleaved into: Matrix protein p15 (MA); RNA-binding phosphoprotein p12 (pp12); Capsid protein p30 (CA); Nucleocapsid protein p10-Pol (NC-pol); Protease (PR) (EC 3.4.23.-) (p14); Reverse transcriptase/ribonuclease H (RT) (EC 2.7.7.49) (EC 2.7.7.7) (EC 3.1.26.4) (p80); Integrase (IN) (EC 2.7.7.-) (EC 3.1.-.-) (p46)] (P03355)
Organism: Moloney murine leukemia virus (isolate Shinnick) (MoMLV)
Function: 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-Pol, or to Gag-Pol binding host factors. Interaction with HECT ubiquitin ligases probably links the viral protein to the host ESCRT pathway and facilitates release.
Subcellular location: [Gag-Pol polyprotein]: Virion {ECO:0000250|UniProtKB:P03332}. Host cell membrane {ECO:0000250|UniProtKB:P03332}; Lipid-anchor {ECO:0000250|UniProtKB:P03332}. Host late endosome membrane {ECO:0000250|UniProtKB:P03332}; Lipid-anchor {ECO:0000250|UniProtKB:P03332}. Host endosome, host multivesicular body {ECO:0000250|UniProtKB:P26807}. Note=These locations are probably linked to virus assembly sites. {ECO:0000305}.; SUBCELLULAR LOCATION: [Matrix protein p15]: Virion {ECO:0000305}.; SUBCELLULAR LOCATION: [Capsid protein p30]: Virion {ECO:0000305}.; SUBCELLULAR LOCATION: [Nucleocapsid protein p10-Pol]: Virion {ECO:0000305}.; SUBCELLULAR LOCATION: [Protease]: Virion {ECO:0000269|PubMed:16603535}.; SUBCELLULAR LOCATION: [RNA-binding phosphoprotein p12]: Host cytoplasm {ECO:0000269|PubMed:21085616, ECO:0000269|PubMed:23300449}. Note=Localizes to the host cytoplasm early in infection and binds to the mitotic chromosomes later on. {ECO:0000269|PubMed:21085616, ECO:0000269|PubMed:23300449}.
