CC   -!- FUNCTION: [Gag-Pol polyprotein]: Mediates, with Gag polyprotein, the
CC       essential events in virion assembly, including binding the plasma
CC       membrane, making the protein-protein interactions necessary to create
CC       spherical particles, recruiting the viral Env proteins, and packaging
CC       the genomic RNA via direct interactions with the RNA packaging sequence
CC       (Psi). Gag-Pol polyprotein may regulate its own translation, by the
CC       binding genomic RNA in the 5'-UTR. At low concentration, the
CC       polyprotein would promote translation, whereas at high concentration,
CC       the polyprotein would encapsidate genomic RNA and then shut off
CC       translation. {ECO:0000250}.
CC   -!- FUNCTION: [Matrix protein p17]: Targets the polyprotein to the plasma
CC       membrane via a multipartite membrane-binding signal, that includes its
CC       myristoylated N-terminus. Matrix protein is part of the pre-integration
CC       complex. Implicated in the release from host cell mediated by Vpu.
CC       Binds to RNA. {ECO:0000250|UniProtKB:P12497}.
CC   -!- FUNCTION: [Capsid protein p24]: Forms the conical core that
CC       encapsulates the genomic RNA-nucleocapsid complex in the virion. Most
CC       core are conical, with only 7% tubular. The core is constituted by
CC       capsid protein hexamer subunits. The core is disassembled soon after
CC       virion entry (By similarity). Host restriction factors such as TRIM5-
CC       alpha or TRIMCyp bind retroviral capsids and cause premature capsid
CC       disassembly, leading to blocks in reverse transcription. Capsid
CC       restriction by TRIM5 is one of the factors which restricts HIV-1 to the
CC       human species. Host PIN1 apparently facilitates the virion uncoating.
CC       On the other hand, interactions with PDZD8 or CYPA stabilize the
CC       capsid. {ECO:0000250|UniProtKB:P04585, ECO:0000250|UniProtKB:P12497}.
CC   -!- FUNCTION: [Nucleocapsid protein p7]: Encapsulates and protects viral
CC       dimeric unspliced genomic RNA (gRNA). Binds these RNAs through its zinc
CC       fingers. Acts as a nucleic acid chaperone which is involved in
CC       rearangement of nucleic acid secondary structure during gRNA
CC       retrotranscription. Also facilitates template switch leading to
CC       recombination. As part of the polyprotein, participates in gRNA
CC       dimerization, packaging, tRNA incorporation and virion assembly.
CC       {ECO:0000250|UniProtKB:P04585}.
CC   -!- FUNCTION: [Protease]: Aspartyl protease that 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. Also cleaves Nef and Vif,
CC       probably concomitantly with viral structural proteins on maturation of
CC       virus particles. Hydrolyzes host EIF4GI and PABP1 in order to shut off
CC       the capped cellular mRNA translation. The resulting inhibition of
CC       cellular protein synthesis serves to ensure maximal viral gene
CC       expression and to evade host immune response (By similarity).
CC       {ECO:0000250|UniProtKB:P04585, ECO:0000255|PROSITE-ProRule:PRU00275}.
CC   -!- FUNCTION: [Reverse transcriptase/ribonuclease H]: Multifunctional
CC       enzyme that converts the viral RNA genome into dsDNA in the cytoplasm,
CC       shortly after virus entry into the cell. This enzyme displays a DNA
CC       polymerase activity that can copy either DNA or RNA templates, and a
CC       ribonuclease H (RNase H) activity that cleaves the RNA strand of RNA-
CC       DNA heteroduplexes in a partially processive 3' to 5' endonucleasic
CC       mode. Conversion of viral genomic RNA into dsDNA requires many steps. A
CC       tRNA(3)-Lys binds to the primer-binding site (PBS) situated at the 5'-
CC       end of the viral RNA. RT uses the 3' end of the tRNA primer to perform
CC       a short round of RNA-dependent minus-strand DNA synthesis. The reading
CC       proceeds through the U5 region and ends after the repeated (R) region
CC       which is 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 two
CC       polypurine tracts (PPTs) situated at the 5'-end and near the center of
CC       the genome. It is not clear if both polymerase and RNase H activities
CC       are 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 PPTs that have not been removed by RNase H as
CC       primers. PPTs 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:0000250|UniProtKB:P04585}.
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, Vpr 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 CA OH's at the 3' ends. In the second step, the PIC
CC       enters cell nucleus. This process is mediated through integrase and Vpr
CC       proteins, and allows the virus to infect a non dividing cell. This
CC       ability to enter the nucleus is specific of lentiviruses, other
CC       retroviruses cannot and rely on cell division to access cell
CC       chromosomes. In the third step, termed strand transfer, the integrase
CC       protein joins the previously processed 3' ends to the 5' ends of
CC       strands of target cellular DNA at the site of integration. The 5'-ends
CC       are produced by integrase-catalyzed staggered cuts, 5 bp apart. A Y-
CC       shaped, gapped, recombination intermediate results, with the 5'-ends of
CC       the viral DNA strands and the 3' ends of target DNA strands remaining
CC       unjoined, flanking a gap of 5 bp. The last step is viral DNA
CC       integration into host chromosome. This involves host DNA repair
CC       synthesis in which the 5 bp gaps between the unjoined strands are
CC       filled in and then ligated. Since this process occurs at both cuts
CC       flanking the HIV genome, a 5 bp duplication of host DNA is produced at
CC       the ends of HIV-1 integration. Alternatively, Integrase may catalyze
CC       the excision of viral DNA just after strand transfer, this is termed
CC       disintegration. {ECO:0000250|UniProtKB:P04585}.

CC   -!- ACTIVITY REGULATION: Protease: The viral protease is inhibited by many
CC       synthetic protease inhibitors (PIs), such as amprenavir, atazanavir,
CC       indinavir, loprinavir, nelfinavir, ritonavir and saquinavir. Use of
CC       protease inhibitors in tritherapy regimens permit more ambitious
CC       therapeutic strategies. Reverse transcriptase/ribonuclease H: RT can be
CC       inhibited either by nucleoside RT inhibitors (NRTIs) or by non
CC       nucleoside RT inhibitors (NNRTIs). NRTIs act as chain terminators,
CC       whereas NNRTIs inhibit DNA polymerization by binding a small
CC       hydrophobic pocket near the RT active site and inducing an allosteric
CC       change in this region. Classical NRTIs are abacavir, adefovir (PMEA),
CC       didanosine (ddI), lamivudine (3TC), stavudine (d4T), tenofovir (PMPA),
CC       zalcitabine (ddC), and zidovudine (AZT). Classical NNRTIs are
CC       atevirdine (BHAP U-87201E), delavirdine, efavirenz (DMP-266), emivirine
CC       (I-EBU), and nevirapine (BI-RG-587). The tritherapies used as a basic
CC       effective treatment of AIDS associate two NRTIs and one NNRTI.

CC   -!- SUBUNIT: [Reverse transcriptase/ribonuclease H]: Heterodimer of p66 RT
CC       and p51 RT (RT p66/p51) (By similarity). Heterodimerization of RT is
CC       essential for DNA polymerase activity (By similarity). The overall
CC       folding of the subdomains is similar in p66 RT and p51 RT but the

CC       Event=Ribosomal frameshifting; Named isoforms=2;
CC         Comment=Translation results in the formation of the Gag polyprotein
CC         most of the time. Ribosomal frameshifting at the gag-pol genes
CC         boundary occurs at low frequency and produces the Gag-Pol
CC         polyprotein. This strategy of translation probably allows the virus
CC         to modulate the quantity of each viral protein. Maintenance of a
CC         correct Gag to Gag-Pol ratio is essential for RNA dimerization and
CC         viral infectivity.;

CC   -!- DOMAIN: [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. {ECO:0000250}.
CC   -!- DOMAIN: [Reverse transcriptase/ribonuclease H]: The tryptophan repeat
CC       motif is involved in RT p66/p51 dimerization (By similarity).
CC       {ECO:0000250}.
CC   -!- DOMAIN: [Integrase]: The core domain contains the D-x(n)-D-x(35)-E
CC       motif, named for the phylogenetically conserved glutamic acid and
CC       aspartic acid residues and the invariant 35 amino acid spacing between
CC       the second and third acidic residues. Each acidic residue of the
CC       D,D(35)E motif is independently essential for the 3'-processing and
CC       strand transfer activities of purified integrase protein.
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. Proteolytic cleavage of p66
CC       RT removes the RNase H domain to yield the p51 RT subunit. Nucleocapsid
CC       protein p7 might be further cleaved after virus entry.
CC       {ECO:0000250|UniProtKB:P04585, ECO:0000255|PROSITE-ProRule:PRU00405}.
CC   -!- MISCELLANEOUS: [Reverse transcriptase/ribonuclease H]: Error-prone
CC       enzyme that lacks a proof-reading function. High mutations rate is a
CC       direct consequence of this characteristic. RT also displays frequent
CC       template switching leading to high recombination rate. Recombination
CC       mostly occurs between homologous regions of the two copackaged RNA
