What is the function of this protein?
Methyltransferase that mediates mRNA cap 2'-O-ribose methylation to the 5'-cap structure of viral mRNAs (PubMed:35944563).  N7-methyl guanosine cap is a prerequisite for binding of nsp16 (PubMed:35944563).  Therefore plays an essential role in viral mRNAs cap methylation which is essential to evade immune system (PubMed:35944563).  May disrupt host mRNA splicing in nucleus by interacting with pre-mRNA Recognition Domains ofthe U1 and U2 snRNAs (PubMed:33080218).
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?
[Host translation inhibitor nsp1]: Host cytoplasm. SUBCELLULAR LOCATION: [Non-structural protein 2]: Host cytoplasm. Host endosome. SUBCELLULAR LOCATION: [Papain-like protease nsp3]: Host membrane; Multi-pass membrane protein. Host cytoplasm. SUBCELLULAR LOCATION: [Non-structural protein 4]: Host membrane; Multi-pass membrane protein. Host cytoplasm. Note=Localizes in virally-induced cytoplasmic double-membrane vesicles. SUBCELLULAR LOCATION: [3C-like proteinase nsp5]: Host cytoplasm. Host Golgi apparatus. SUBCELLULAR LOCATION: [Non-structural protein 6]: Host membrane; Multi-pass membrane protein. SUBCELLULAR LOCATION: [Non-structural protein 7]: Host cytoplasm, host perinuclear region. Host cytoplasm. Host endoplasmic reticulum.
