Protein attributes

Sequence length	1189 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Inferred from homology

General annotation (Comments)

Function	During replicative cycle of retroviruses, the reverse-transcribed viral DNA is integrated into the host chromosome by the viral integrase enzyme. RNase H activity is associated with the reverse transcriptase.
Catalytic activity	Deoxynucleoside triphosphate + DNA(n) = diphosphate + DNA(n+1). Endonucleolytic cleavage to 5'-phosphomonoester.
Post-translational modification	Specific enzymatic cleavages in vivo yield mature proteins.
Miscellaneous	This protein is synthesized as a Gag-Pol polyprotein.
Sequence similarities	Belongs to the retroviral Pol polyprotein family. Contains 1 integrase catalytic domain. Contains 1 peptidase A2 domain. Contains 1 reverse transcriptase domain. Contains 1 RNase H domain.
Sequence caution	The sequence BAA89659.1 differs from that shown. Reason: Erroneous initiation.
