What is the function of this protein?
Binds to the 40S ribosomal subunit and inhibits host translation.  The nsp1-40S ribosome complex further induces an endonucleolytic cleavage near the 5'UTR of host mRNAs, targeting them for degradation.  By suppressing host gene expression, nsp1 facilitates efficient viral gene expression in infected cells and evasion from host immune response (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?
[Non-structural protein 3]: Host membrane; Multi-pass membrane protein. SUBCELLULAR LOCATION: [Non-structural protein 4]: Host membrane; Multi-pass membrane protein. SUBCELLULAR LOCATION: [Non-structural protein 6]: Host membrane; Multi-pass membrane protein. SUBCELLULAR LOCATION: [Non-structural protein 7]: Host cytoplasm, host perinuclear region. Note=nsp7, nsp8, nsp9 and nsp10 are localized in cytoplasmic foci, largely perinuclear. Late in infection, they merge into confluent complexes (By similarity). SUBCELLULAR LOCATION: [Non-structural protein 8]: Host cytoplasm, host perinuclear region. Note=nsp7, nsp8, nsp9 and nsp10 are localized in cytoplasmic foci, largely perinuclear. Late in infection, they merge into confluent complexes (By similarity). SUBCELLULAR LOCATION: [Non-structural protein 9]: Host cytoplasm, host perinuclear region.
