What is the function of this protein?
Methyltransferase that mediates mRNA cap 2'-O-ribose methylation to the 5'-cap structure of viral mRNAs.  N7-methyl guanosine cap is a prerequisite for binding of nsp16.  Therefore plays an essential role in viral mRNAs cap methylation which is essential to evade immune system.
What are the official names of this protein?
Replicase polyprotein 1ab, pp1ab, ORF1ab 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=Gammacoronaviruses induce membrane zippering to form zippered endoplasmic reticulum (zER). 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. SUBCELLULAR LOCATION: [Helicase]: Host endoplasmic reticulum-Golgi intermediate compartment. Note=The helicase interacts with the N protein in membranous complexes and colocalizes with sites of synthesis of new viral RNA. SUBCELLULAR LOCATION: [Proofreading exoribonuclease]: Host cytoplasm. Host endoplasmic reticulum. SUBCELLULAR LOCATION: [Uridylate-specific endoribonuclease]: Host cytoplasm. Host endoplasmic reticulum.
