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 links 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 (By similarity). Binds with
CC high affinity to conserved UCUG elements within the packaging signal,
CC located near the 5'-end of the genome (By similarity). This binding is
CC dependent on genome dimerization (By similarity). Acts as a nucleic
CC acid chaperone which is involved in rearrangement of nucleic acid
CC secondary structures during gRNA retrotranscription (By similarity).
CC {ECO:0000250|UniProtKB:P03332, 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. {ECO:0000255|PROSITE-
CC ProRule:PRU00275}.
CC -!- FUNCTION: Reverse transcriptase/ribonuclease H: RT is a multifunctional
CC enzyme that converts the viral dimeric RNA genome into dsDNA in the
CC cytoplasm, shortly after virus entry into the cell. This enzyme
CC displays a DNA polymerase activity that can copy either DNA or RNA
CC templates, and a ribonuclease H (RNase H) activity that cleaves the RNA
CC 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: [Protease/Reverse transcriptase/ribonuclease H]: The reverse
CC transcriptase is a monomer (Potential). Interacts (via RNase domains)
CC with host release factor ETF1; this interaction is essential for
CC translational readthrough of amber codon between viral gag and pol
CC genes, as well as for viral replication.
CC {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 polyprotein: Late-budding domains (L domains) are short
CC sequence motifs essential for viral particle budding. They recruit
CC proteins of the host ESCRT machinery (Endosomal Sorting Complex
CC Required for Transport) or ESCRT-associated proteins. RNA-binding
CC phosphoprotein p12 contains one L domain: a PPXY motif which
CC potentially interacts with the WW domain 3 of NEDD4 E3 ubiquitin
CC ligase. Matrix protein p15 contains one L domain: a PTAP/PSAP motif,
CC which potentially interacts with the UEV domain of TSG101.
CC {ECO:0000250|UniProtKB:P03332}.
CC -!- DOMAIN: The reverse transcriptase/ribonuclease H (RT) is structured in
CC five subdomains: finger, palm, thumb, connection and RNase H. Within
CC the palm subdomain, the 'primer grip' region is thought to be involved
CC in the positioning of the primer terminus for accommodating the
CC incoming nucleotide. The RNase H domain stabilizes the association of
CC RT with primer-template (By similarity). {ECO:0000250}.
CC -!- DOMAIN: Integrase core domain contains the D-x(n)-D-x(35)-E motif,
CC named for the phylogenetically conserved glutamic acid and aspartic
CC acid residues and the invariant 35 amino acid spacing between the
CC second and third acidic residues. Each acidic residue of the D,D(35)E
CC motif is independently essential for the 3'-processing and strand
CC transfer activities of purified integrase protein (By similarity).
CC {ECO:0000250}.
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: [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 521-Asp and 523-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}.
