CC   -!- FUNCTION: [Gag-Pol polyprotein]: Plays a role in budding and is
CC       processed by the viral protease during virion maturation outside the
CC       cell. During budding, it recruits, in a PPXY-dependent or independent
CC       manner, Nedd4-like ubiquitin ligases that conjugate ubiquitin molecules
CC       to Gag-Pol, or to Gag-Pol binding host factors. Interaction with HECT
CC       ubiquitin ligases probably link the viral protein to the host ESCRT
CC       pathway and facilitates release. {ECO:0000250|UniProtKB:P03332}.
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 pre-integration complex.
CC       {ECO:0000250|UniProtKB:P03332}.
CC   -!- FUNCTION: [RNA-binding phosphoprotein p12]: Constituent of the pre-
CC       integration complex (PIC) which tethers the latter to mitotic
CC       chromosomes. This allows the integration of the viral genome into the
CC       host DNA. {ECO:0000250|UniProtKB:P03355}.
CC   -!- FUNCTION: [Capsid protein p30]: Forms the spherical core of the virion
CC       that encapsulates the genomic RNA-nucleocapsid complex.
CC       {ECO:0000250|UniProtKB:P03336}.
CC   -!- FUNCTION: [Nucleocapsid protein p10-Pol]: Involved in the packaging and
CC       encapsidation of two copies of the genome. Binds with high affinity to
CC       conserved UCUG elements within the packaging signal, located near the
CC       5'-end of the genome. This binding is dependent on genome dimerization.
CC       Acts as a nucleic acid chaperone which is involved in rearrangement of
CC       nucleic acid secondary structures during gRNA retrotranscription (By
CC       similarity). {ECO:0000250|UniProtKB:P03332,
CC       ECO:0000250|UniProtKB:P03355}.
CC   -!- FUNCTION: [Protease]: The aspartyl protease mediates proteolytic
CC       cleavages of Gag and Gag-Pol polyproteins during or shortly after the
CC       release of the virion from the plasma membrane. Cleavages take place as
CC       an ordered, step-wise cascade to yield mature proteins. This process is
CC       called maturation. Displays maximal activity during the budding process
CC       just prior to particle release from the cell (Potential). Cleaves the
CC       translation initiation factor eIF4G leading to the inhibition of host
CC       cap-dependent translation (By similarity).
CC       {ECO:0000250|UniProtKB:P03332, ECO:0000255|PROSITE-ProRule:PRU00275}.
CC   -!- FUNCTION: [Reverse transcriptase/ribonuclease H]: RT is a
CC       multifunctional enzyme that converts the viral dimeric RNA genome into
CC       dsDNA in the cytoplasm, shortly after virus entry into the cell. This
CC       enzyme displays a DNA polymerase activity that can copy either DNA or
CC       RNA templates, and a ribonuclease H (RNase H) activity that cleaves the
CC       RNA strand of RNA-DNA heteroduplexes in a partially processive 3' to 5'
CC       endonucleasic mode. Conversion of viral genomic RNA into dsDNA requires
CC       many steps. A tRNA binds to the primer-binding site (PBS) situated at
CC       the 5' end of the viral RNA. RT uses the 3' end of the tRNA primer to
CC       perform a short round of RNA-dependent minus-strand DNA synthesis. The
CC       reading proceeds through the U5 region and ends after the repeated (R)
CC       region which is present at both ends of viral RNA. The portion of the
CC       RNA-DNA heteroduplex is digested by the RNase H, resulting in a ssDNA
CC       product attached to the tRNA primer. This ssDNA/tRNA hybridizes with
CC       the identical R region situated at the 3' end of viral RNA. This
CC       template exchange, known as minus-strand DNA strong stop transfer, can
CC       be either intra- or intermolecular. RT uses the 3' end of this newly
CC       synthesized short ssDNA to perform the RNA-dependent minus-strand DNA
CC       synthesis of the whole template. RNase H digests the RNA template
CC       except for a polypurine tract (PPT) situated at the 5' end of the
CC       genome. It is not clear if both polymerase and RNase H activities are
CC       simultaneous. RNase H probably can proceed both in a polymerase-
CC       dependent (RNA cut into small fragments by the same RT performing DNA
CC       synthesis) and a polymerase-independent mode (cleavage of remaining RNA
CC       fragments by free RTs). Secondly, RT performs DNA-directed plus-strand
CC       DNA synthesis using the PPT that has not been removed by RNase H as
CC       primers. PPT and tRNA primers are then removed by RNase H. The 3' and
CC       5' ssDNA PBS regions hybridize to form a circular dsDNA intermediate.
CC       Strand displacement synthesis by RT to the PBS and PPT ends produces a
CC       blunt ended, linear dsDNA copy of the viral genome that includes long
CC       terminal repeats (LTRs) at both ends. {ECO:0000255}.
CC   -!- FUNCTION: [Integrase]: Catalyzes viral DNA integration into the host
CC       chromosome, by performing a series of DNA cutting and joining
CC       reactions. This enzyme activity takes place after virion entry into a
CC       cell and reverse transcription of the RNA genome in dsDNA. The first
CC       step in the integration process is 3' processing. This step requires a
CC       complex comprising the viral genome, matrix protein and integrase. This
CC       complex is called the pre-integration complex (PIC). The integrase
CC       protein removes 2 nucleotides from each 3' end of the viral DNA,
CC       leaving recessed CA OH's at the 3' ends. In the second step that
CC       requires cell division, the PIC enters cell nucleus. In the third step,
CC       termed strand transfer, the integrase protein joins the previously
CC       processed 3' ends to the 5' ends of strands of target cellular DNA at
CC       the site of integration. The last step is viral DNA integration into
CC       host chromosome. {ECO:0000250|UniProtKB:P03355}.

CC   -!- SUBUNIT: [Capsid protein p30]: Homohexamer; further associates as

CC       formed from hexagonal rings, each containing six capsid monomers (By
CC       similarity). {ECO:0000250|UniProtKB:P03355}.

CC       {ECO:0000250|UniProtKB:P03355}. Note=Localizes to the host cytoplasm
CC       early in infection and binds to the mitotic chromosomes later on.
CC       {ECO:0000250|UniProtKB:P03355}.
CC   -!- DOMAIN: [Gag-Pol polyprotein]: Late-budding domains (L domains) are
CC       short sequence motifs essential for viral particle release. They can
CC       occur individually or in close proximity within structural proteins.
CC       They interacts with sorting cellular proteins of the multivesicular
CC       body (MVB) pathway. Most of these proteins are class E vacuolar protein
CC       sorting factors belonging to ESCRT-I, ESCRT-II or ESCRT-III complexes.
CC       RNA-binding phosphoprotein p12 contains one L domain: a PPXY motif
CC       which potentially interacts with the WW domain 3 of NEDD4 E3 ubiquitin
CC       ligase. PPXY motif is essential for virus egress. Matrix protein p15
CC       contains one L domain: a PTAP/PSAP motif, which potentially interacts
CC       with the UEV domain of TSG101. The junction between the matrix protein
CC       p15 and RNA-binding phosphoprotein p12 also contains one L domain: a
CC       LYPX(n)L motif which potentially interacts with PDCD6IP. Both PSAP and
CC       LYPX(n)L domains might play little to no role in budding and possibly
CC       drive residual virus release. contains. {ECO:0000250|UniProtKB:P03332}.
CC   -!- PTM: [Gag-Pol polyprotein]: Ubiquitinated by ITCH. Gag can recruit the
CC       ubiquitin ligase Itch in an L domain-independent manner to facilitate
CC       virus release via a mechanism that involves Gag ubiquitination.
CC       {ECO:0000250|UniProtKB:P03332}.
CC   -!- PTM: [Gag-Pol polyprotein]: Specific enzymatic cleavages by the viral
CC       protease yield mature proteins. The protease is released by
CC       autocatalytic cleavage. The polyprotein is cleaved during and after
CC       budding, this process is termed maturation.
CC       {ECO:0000250|UniProtKB:P03355}.
CC   -!- PTM: [Capsid protein p30]: Sumoylated; which is required for virus
CC       replication. {ECO:0000250|UniProtKB:P03355}.
CC   -!- PTM: [RNA-binding phosphoprotein p12]: Phosphorylated on serine
CC       residues. {ECO:0000250|UniProtKB:P03355}.
CC   -!- MISCELLANEOUS: [Gag-Pol polyprotein]: This protein is translated as a
CC       gag-pol fusion protein by episodic readthrough of the gag protein
CC       termination codon. Readthrough of the terminator codon TAG occurs
CC       between the codons for 537-Asp and 539-Gly.
CC       {ECO:0000250|UniProtKB:P03355}.
CC   -!- MISCELLANEOUS: [Nucleocapsid protein p10-Pol]: Nucleocapsid protein
CC       p10-Pol released from Pol polyprotein (NC-pol) is a few amino acids
CC       shorter than the nucleocapsid protein p10 released from Gag polyprotein
CC       (NC-gag). {ECO:0000250|UniProtKB:P03355}.
CC   -!- MISCELLANEOUS: [Reverse transcriptase/ribonuclease H]: The reverse
CC       transcriptase is an error-prone enzyme that lacks a proof-reading
CC       function. High mutations rate is a direct consequence of this
CC       characteristic. RT also displays frequent template swiching leading to
CC       high recombination rate. Recombination mostly occurs between homologous
CC       regions of the two copackaged RNA genomes. If these two RNA molecules
CC       derive from different viral strains, reverse transcription will give
CC       rise to highly recombinated proviral DNAs. {ECO:0000255|PROSITE-
CC       ProRule:PRU00405}.
CC   -!- SIMILARITY: Belongs to the retroviral Pol polyprotein family.
