CC -!- FUNCTION: Gag polyprotein plays a role in budding and is processed by
CC the viral protease during virion maturation outside the cell. During
CC budding, it recruits, in a PPXY-dependent or independent manner, Nedd4-
CC like ubiquitin ligases that conjugate ubiquitin molecules to Gag, or to
CC Gag binding host factors. Interaction with HECT ubiquitin ligases
CC probably link the viral protein to the host ESCRT pathway and
CC facilitate release (By similarity). {ECO:0000250}.
CC -!- FUNCTION: Matrix protein p15 targets Gag and gag-pol polyproteins to
CC the plasma membrane via a multipartite membrane binding signal, that
CC includes its myristoylated N-terminus. Also mediates nuclear
CC localization of the preintegration complex (By similarity).
CC {ECO:0000250}.
CC -!- FUNCTION: Capsid protein p30 forms the spherical core of the virion
CC that encapsulates the genomic RNA-nucleocapsid complex. {ECO:0000250}.
CC -!- FUNCTION: Nucleocapsid protein p10 is involved in the packaging and
CC encapsidation of two copies of the genome. Binds with high affinity to
CC conserved elements within the packaging signal, located near the 5'-end
CC of the genome. This binding is dependent on genome dimerization (By
CC similarity). {ECO:0000250}.
CC -!- SUBUNIT: Capsid protein p30 is a homohexamer, that further associates
CC as homomultimer. The virus core is composed of a lattice formed from
CC hexagonal rings, each containing six capsid monomers (By similarity).
CC {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: [Gag polyprotein]: Virion {ECO:0000250}. Host
CC cell membrane {ECO:0000305}; Lipid-anchor {ECO:0000305}. Host late
CC endosome membrane {ECO:0000305}; Lipid-anchor {ECO:0000305}. Host
CC endosome, host multivesicular body {ECO:0000250}. Note=These locations
CC are probably linked to virus assembly sites. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: [Matrix protein p15]: Virion {ECO:0000305}.
CC -!- SUBCELLULAR LOCATION: [Capsid protein p30]: Virion {ECO:0000305}.
CC -!- SUBCELLULAR LOCATION: [Nucleocapsid protein p10]: Virion {ECO:0000305}.
CC -!- DOMAIN: Late-budding domains (L domains) are short sequence motifs
CC essential for viral particle budding. They recruit proteins of the host
CC ESCRT machinery (Endosomal Sorting Complex Required for Transport) or
CC ESCRT-associated proteins. RNA-binding phosphoprotein p12 contains one
CC L domain: a PPXY motif which potentially interacts with the WW domain 3
CC of NEDD4 E3 ubiquitin ligase. Matrix protein p15 contains one L domain:
CC a PTAP/PSAP motif, which potentially interacts with the UEV domain of
CC TSG101. The junction between the matrix protein p15 and RNA-binding
CC phosphoprotein p12 also contains one L domain: a LYPX(n)L motif which
CC potentially interacts with PDCD6IP (By similarity). {ECO:0000250}.
CC -!- PTM: Specific enzymatic cleavages by the viral protease yield mature
CC proteins. The protease is released by autocatalytic cleavage. The
CC polyprotein is cleaved during and after budding, this process is termed
CC maturation (By similarity). {ECO:0000250}.
CC -!- PTM: RNA-binding phosphoprotein p12 is phosphorylated on serine
CC residues. {ECO:0000250}.
CC -!- CAUTION: Originally thought to be characterized from prostate tumors,
CC the described gammaretrovirus XMRV is in fact laboratory-derived and
CC there is no association of XMRV with prostate cancer.
