CC -!- FUNCTION: The 3C-like serine proteinase is responsible for the majority
CC of cleavages.
CC -!- SUBCELLULAR LOCATION: [Non-structural protein 1]: Host membrane
CC {ECO:0000305}; Multi-pass membrane protein {ECO:0000305}.
CC -!- SUBCELLULAR LOCATION: [Non-structural protein 2]: Host membrane
CC {ECO:0000305}; Multi-pass membrane protein {ECO:0000305}.
CC -!- SUBCELLULAR LOCATION: [Non-structural protein 4]: Host membrane
CC {ECO:0000305}; Multi-pass membrane protein {ECO:0000305}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Ribosomal frameshifting; Named isoforms=2;
CC Name=Replicase polyprotein 1a; Synonyms=pp1a, ORF1a polyprotein;
CC IsoId=Q008X5-1; Sequence=Displayed;
CC Name=Replicase polyprotein 1ab; Synonyms=pp1ab;
CC IsoId=Q008X6-1; Sequence=External;
CC -!- DOMAIN: The hydrophobic domains (HD) could mediate the membrane
CC association of the replication complex and thereby alter the
CC architecture of the host cell membrane. {ECO:0000250}.
CC -!- PTM: Specific enzymatic cleavages in vivo by its own protease yield
CC mature proteins. 3CL-PRO is autocatalytically processed (By
CC similarity). {ECO:0000250}.
CC -!- MISCELLANEOUS: [Isoform Replicase polyprotein 1a]: Produced by
CC conventional translation.
