What is the function of this protein?
Catalyzes viral DNA integration into the host chromosome, by performing a series of DNA cutting and joining reactions.  This enzyme activity takes place after virion entry into a cell and reverse transcription of the RNA genome in dsDNA.  The first step in the integration process is 3' processing.  This step requires a complex comprising the viral genome, matrix protein and integrase.  This complex is called the pre-integration complex (PIC).  The integrase protein removes 2 nucleotides from each 3' end of the viral DNA, leaving recessed CA OH's at the 3' ends.  In the second step that requires cell division, the PIC enters cell nucleus.  In the third step, termed strand transfer, the integrase protein joins the previously processed 3' ends to the 5' ends of strands of target cellular DNA at the site of integration.  The last step is viral DNA integration into host chromosome.
What are the official names of this protein?
Gag-Pol polyprotein.
What is the protein family that this protein belongs to?
Belongs to the retroviral Pol polyprotein family.
What are the subcellular locations of this protein?
[Gag-Pol polyprotein]: Virion. Host cell membrane; Lipid-anchor. Host late endosome membrane; Lipid-anchor. Host endosome, host multivesicular body. Note=These locations are probably linked to virus assembly sites. SUBCELLULAR LOCATION: [Matrix protein p15]: Virion. SUBCELLULAR LOCATION: [Capsid protein p30]: Virion. SUBCELLULAR LOCATION: [Nucleocapsid protein p10-Pol]: Virion. SUBCELLULAR LOCATION: [Protease]: Virion. SUBCELLULAR LOCATION: [RNA-binding phosphoprotein p12]: Host cytoplasm. Note=Localizes to the host cytoplasm early in infection and binds to the mitotic chromosomes later on.
