CC -!- FUNCTION: Matrix protein p19 targets Gag, Gag-Pro and Gag-Pro-Pol
CC polyproteins to the plasma membrane via a multipartite membrane binding
CC signal, that includes its myristoylated N-terminus. Also mediates
CC nuclear localization of the preintegration complex (By similarity).
CC {ECO:0000250}.
CC -!- FUNCTION: Capsid protein p24 forms the conical core of the virus that
CC encapsulates the genomic RNA-nucleocapsid complex. {ECO:0000250}.
CC -!- FUNCTION: Nucleocapsid protein p15 is involved in the packaging and
CC encapsidation of two copies of the genome. {ECO:0000250}.
CC -!- FUNCTION: The aspartyl protease mediates proteolytic cleavages of Gag,
CC Gag-Pro and Gag-Pro-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. Hydrolyzes host EIF4GI in
CC order to shut off the capped cellular mRNA translation. The resulting
CC inhibition of cellular protein synthesis serves to ensure maximal viral
CC gene expression and to evade host immune response (By similarity).
CC {ECO:0000250}.
CC -!- FUNCTION: Reverse transcriptase (RT) is a multifunctional enzyme that
CC converts the viral RNA genome into dsDNA in the cytoplasm, shortly
CC after virus entry into the cell. This enzyme displays a DNA polymerase
CC activity that can copy either DNA or RNA templates, and a ribonuclease
CC H (RNase H) activity that cleaves the RNA strand of RNA-DNA
CC heteroduplexes in a partially processive 3' to 5'-endonucleasic mode.
CC Conversion of viral genomic RNA into dsDNA requires many steps. A tRNA-
CC Pro binds to the primer-binding site (PBS) situated at the 5'-end of
CC the viral RNA. RT uses the 3' end of the tRNA primer to perform a short
CC round of RNA-dependent minus-strand DNA synthesis. The reading proceeds
CC through the U5 region and ends after the repeated (R) region which is
CC present at both ends of viral RNA. The portion of the RNA-DNA
CC heteroduplex is digested by the RNase H, resulting in a ssDNA product
CC attached to the tRNA primer. This ssDNA/tRNA hybridizes with the
CC identical R region situated at the 3' end of viral RNA. This template
CC exchange, known as minus-strand DNA strong stop transfer, can be either
CC intra- or intermolecular. RT uses the 3' end of this newly synthesized
CC short ssDNA to perform the RNA-dependent minus-strand DNA synthesis of
CC the whole template. RNase H digests the RNA template except for a
CC polypurine tract (PPT) situated at the 5' end of the genome. It is not
CC clear if both polymerase and RNase H activities are simultaneous. RNase
CC H probably can proceed both in a polymerase-dependent (RNA cut into
CC small fragments by the same RT performing DNA synthesis) and a
CC polymerase-independent mode (cleavage of remaining RNA fragments by
CC free RTs). Secondly, RT performs DNA-directed plus-strand DNA synthesis
CC using the PPT that has not been removed by RNase H as primer. PPT and
CC tRNA primers are then removed by RNase H. The 3' and 5' ssDNA PBS
CC regions hybridize to form a circular dsDNA intermediate. Strand
CC displacement synthesis by RT to the PBS and PPT ends produces a blunt
CC ended, linear dsDNA copy of the viral genome that includes long
CC terminal repeats (LTRs) at both ends (By similarity). {ECO:0000250}.
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.
CC This 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 dinucleotides OH's at the 3' ends. In the second step,
CC the PIC access cell chromosomes during cell division. 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 5'-ends are produced by integrase-
CC catalyzed staggered cuts, 5 bp apart. A Y-shaped, gapped, recombination
CC intermediate results, with the 5'-ends of the viral DNA strands and the
CC 3' ends of target DNA strands remaining unjoined, flanking a gap of 5
CC bp. The last step is viral DNA integration into host chromosome. This
CC involves host DNA repair synthesis in which the 5 bp gaps between the
CC unjoined strands (see above) are filled in and then ligated (By
CC similarity). {ECO:0000250}.

CC -!- DOMAIN: Late-budding domains (L domains) are short sequence motifs
CC essential for viral particle release. They can occur individually or in
CC close proximity within structural proteins. They interacts with sorting
CC cellular proteins of the multivesicular body (MVB) pathway. Most of
CC these proteins are class E vacuolar protein sorting factors belonging
CC to ESCRT-I, ESCRT-II or ESCRT-III complexes. Matrix protein p19
CC contains two L domains: a PTAP/PSAP motif which interacts with the UEV
CC domain of TSG101, and a PPXY motif which binds to the WW domains of
CC HECT (homologous to E6-AP C-terminus) E3 ubiquitin ligases (By
CC similarity). {ECO:0000250}.
CC -!- DOMAIN: The capsid protein N-terminus seems to be involved in Gag-Gag
CC interactions. {ECO:0000250}.
CC -!- PTM: Specific enzymatic cleavages by the viral protease yield mature
CC proteins. The polyprotein is cleaved during and after budding, this
CC process is termed maturation. The protease is autoproteolytically
CC processed at its N- and C-termini (By similarity). {ECO:0000250}.
CC -!- MISCELLANEOUS: The reverse transcriptase is an error-prone enzyme that
CC lacks a proof-reading function. High mutations rate is a direct
CC consequence of this characteristic. RT also displays frequent template
CC switching leading to high recombination rate. Recombination mostly
CC occurs between homologous regions of the two copackaged RNA genomes. If
CC these two RNA molecules derive from different viral strains, reverse
CC transcription will give rise to highly recombinated proviral DNAs (By
CC similarity). {ECO:0000250}.
CC -!- MISCELLANEOUS: [Isoform Gag-Pol polyprotein]: Produced by -1 ribosomal
CC frameshifting at the gag-pol genes boundary.
