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. Also mediates cleavage of
CC host YTHDF3. Mediates cleavage of host CARD8, thereby activating the
CC CARD8 inflammasome, leading to the clearance of latent HIV-1 in patient
CC CD4(+) T-cells after viral reactivation; in contrast, HIV-1 can evade
CC CARD8-sensing when its protease remains inactive in infected cells
CC prior to viral budding (By similarity). {ECO:0000250|UniProtKB:P04585,
CC 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 -!- ALTERNATIVE PRODUCTS:
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 Name=Gag polyprotein;
CC IsoId=Q79665-1; Sequence=External;
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 -!- PTM: [Matrix protein p17]: Tyrosine phosphorylated presumably in the
CC virion by a host kinase. Phosphorylation is apparently not a major
CC regulator of membrane association. {ECO:0000250|UniProtKB:P04585}.
CC -!- PTM: [Capsid protein p24]: Phosphorylated possibly by host MAPK1; this
CC phosphorylation is necessary for Pin1-mediated virion uncoating.
CC {ECO:0000250|UniProtKB:P12493}.
CC -!- PTM: [Nucleocapsid protein p7]: Methylated by host PRMT6, impairing its
CC function by reducing RNA annealing and the initiation of reverse
CC transcription. {ECO:0000250|UniProtKB:P03347}.
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
CC genomes. If these two RNA molecules derive from different viral
CC strains, reverse transcription will give rise to highly recombinated
CC proviral DNAs. {ECO:0000250}.
CC -!- MISCELLANEOUS: HIV-1 lineages are divided in three main groups, M (for
CC Major), O (for Outlier), and N (for New, or Non-M, Non-O). The vast
CC majority of strains found worldwide belong to the group M. Group O
CC seems to be endemic to and largely confined to Cameroon and neighboring
CC countries in West Central Africa, where these viruses represent a small
CC minority of HIV-1 strains. The group N is represented by a limited
CC number of isolates from Cameroonian persons. The group M is further
CC subdivided in 9 clades or subtypes (A to D, F to H, J and K).
CC -!- MISCELLANEOUS: Resistance to inhibitors associated with mutations are
CC observed both in viral protease and in reverse transcriptase. Most of
CC the time, single mutations confer only a modest reduction in drug
CC susceptibility. Combination of several mutations is usually required to
CC develop a high-level drug resistance. These mutations are predominantly
CC found in clade B viruses and not in other genotypes. They are listed in
CC the clade B representative isolate HXB2 (AC P04585).
CC -!- MISCELLANEOUS: [Isoform Gag-Pol polyprotein]: Produced by -1 ribosomal
CC frameshifting.
