Pol (DNA polymerase) refers to a gene in retroviruses, or the protein produced by that gene.

• Reverse transcriptase (RT), which transcribes the viral RNA into double-stranded DNA.
• Integrase, which integrates the DNA produced by RT into the host cell's genome.
• Protease, an enzyme that cuts proteins into segments. HIV's gag and pol genes do not encode their proteins in their final form but as larger polyproteins that the HIV protease cleaves into separate functional units.
