Protein: Gag-Pol polyprotein (Pr160Gag-Pol) [Cleaved into: Matrix protein p17 (MA); Capsid protein p24 (CA); Spacer peptide 1 (SP1) (p2); Nucleocapsid protein p7 (NC); Transframe peptide (TF); p6-pol (p6*); Protease (EC 3.4.23.16) (PR) (Retropepsin); Reverse transcriptase/ribonuclease H (EC 2.7.7.49) (EC 2.7.7.7) (EC 3.1.26.13) (Exoribonuclease H) (EC 3.1.13.2) (p66 RT); p51 RT; p15; Integrase (IN) (EC 2.7.7.-) (EC 3.1.-.-)] (P12497)
Organism: Human immunodeficiency virus type 1 group M subtype B (isolate NY5) (HIV-1)
Function: Mediates, with Gag polyprotein, the essential events in virion assembly, including binding the plasma membrane, making the protein-protein interactions necessary to create spherical particles, recruiting the viral Env proteins, and packaging the genomic RNA via direct interactions with the RNA packaging sequence (Psi). Gag-Pol polyprotein may regulate its own translation, by the binding genomic RNA in the 5'-UTR. At low concentration, the polyprotein would promote translation, whereas at high concentration, the polyprotein would encapsidate genomic RNA and then shut off translation.
Subcellular location: [Gag-Pol polyprotein]: Host cell membrane; Lipid-anchor {ECO:0000269|PubMed:19297499}. Host endosome, host multivesicular body {ECO:0000269|PubMed:19297499}. Note=These locations are linked to virus assembly sites. The main location is the cell membrane, but under some circumstances, late endosomal compartments can serve as productive sites for virion assembly. {ECO:0000269|PubMed:19297499}.; SUBCELLULAR LOCATION: [Matrix protein p17]: Virion membrane; Lipid-anchor {ECO:0000305}.
