What is the function of this protein?
Plays a pivotal role in viral transcription by stimulating both nsp14 3'-5' exoribonuclease and nsp16 2'-O-methyltransferase activities (By similarity).  Therefore plays an essential role in viral mRNAs cap methylation (By similarity).
What are the official names of this protein?
Replicase polyprotein 1a, pp1a, ORF1a polyprotein.
What is the protein family that this protein belongs to?
Belongs to the coronaviruses polyprotein 1ab family.
What are the subcellular locations of this protein?
[Papain-like protease]: Host endoplasmic reticulum membrane; Multi-pass membrane protein. Host cytoplasm. Note=Gammacoronaviruses induce membrane zippering to form zippered endoplasmic reticulum (zER). SUBCELLULAR LOCATION: [Non-structural protein 4]: Host endoplasmic reticulum membrane; Multi-pass membrane protein. Host cytoplasm. Note=Localizes in virally-induced cytoplasmic double-membrane vesicles (By similarity). Gammacoronaviruses induce membrane zippering to form zippered endoplasmic reticulum (zER) (By similarity). SUBCELLULAR LOCATION: [Non-structural protein 6]: Host endoplasmic reticulum membrane; Multi-pass membrane protein. Note=Gammacoronaviruses induce membrane zippering to form zippered endoplasmic reticulum (zER). SUBCELLULAR LOCATION: [Non-structural protein 7]: Host cytoplasm, host perinuclear region. Host cytoplasm. Host endoplasmic reticulum. Note=nsp7, nsp8, nsp9 and nsp10 are localized in cytoplasmic foci, largely perinuclear. Late in infection, they merge into confluent complexes. SUBCELLULAR LOCATION: [Non-structural protein 8]: Host cytoplasm, host perinuclear region. Host cytoplasm. Host endoplasmic reticulum. Note=nsp7, nsp8, nsp9 and nsp10 are localized in cytoplasmic foci, largely perinuclear. Late in infection, they merge into confluent complexes. SUBCELLULAR LOCATION: [Non-structural protein 9]: Host cytoplasm, host perinuclear region. Host cytoplasm. Host endoplasmic reticulum. Note=nsp7, nsp8, nsp9 and nsp10 are localized in cytoplasmic foci, largely perinuclear. Late in infection, they merge into confluent complexes. SUBCELLULAR LOCATION: [Non-structural protein 10]: Host cytoplasm, host perinuclear region. Host cytoplasm. Host endoplasmic reticulum. Note=nsp7, nsp8, nsp9 and nsp10 are localized in cytoplasmic foci, largely perinuclear. Late in infection, they merge into confluent complexes.
