CC -!- FUNCTION: Retroviral proteases have roles in the processing of the
CC primary translation products and the maturation of the viral particle.
CC Endogenous Pro proteins may have kept, lost or modified their original
CC function during evolution.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Processing at the authentic HIV-1 PR recognition site and
CC release of the mature p17 matrix and the p24 capsid protein, as a
CC result of the cleavage of the -SQNY-|-PIVQ- cleavage site.;
CC EC=3.4.23.50;
CC -!- SUBUNIT: Active as a homodimer. {ECO:0000250}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Ribosomal frameshifting; Named isoforms=1;
CC Comment=This protein is synthesized as Gag-Pro and Gag-Pro-Pol
CC polyprotein. These polyproteins are thought, by similarity with
CC type-B retroviruses, to be generated by -1 frameshifts occurring at
CC the Gag-Pro and Pro-Pol genes boundaries.;
CC Name=1;
CC IsoId=P63120-1; Sequence=Displayed;
CC -!- PTM: Autoproteolytically processed at the N-terminus. Expected C-
CC terminal autoprocessing not detected. The sequence shown is that of the
CC processed Pro protein (By similarity). {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the peptidase A2 family. HERV class-II K(HML-2)
CC subfamily. {ECO:0000305}.
