What is the function of this protein?
Replicates the viral (+) and (-) RNA genome, and performs the capping of genomes in the cytoplasm.  NS5 methylates viral RNA cap at guanine N-7 and ribose 2'-O positions.  Besides its role in RNA genome replication, also prevents the establishment of cellular antiviral state by blocking the interferon-alpha/beta (IFN-alpha/beta) signaling pathway.  Inhibits host TYK2 and STAT2 phosphorylation, thereby preventing activation of JAK-STAT signaling pathway.
What are the official names of this protein?
Genome polyprotein.
What is the protein family that this protein belongs to?
In the N-terminal section; belongs to the class I-like SAM-binding methyltransferase superfamily. mRNA cap 0-1 NS5-type methyltransferase family.
What are the subcellular locations of this protein?
[Capsid protein C]: Virion. Host nucleus. Host cytoplasm. Host cytoplasm, host perinuclear region. SUBCELLULAR LOCATION: [Peptide pr]: Secreted. SUBCELLULAR LOCATION: [Small envelope protein M]: Virion membrane; Multi-pass membrane protein. Host endoplasmic reticulum membrane; Multi-pass membrane protein. Note=ER membrane retention is mediated by the transmembrane domains. SUBCELLULAR LOCATION: [Envelope protein E]: Virion membrane; Multi-pass membrane protein. Host endoplasmic reticulum membrane; Multi-pass membrane protein. Note=ER membrane retention is mediated by the transmembrane domains. SUBCELLULAR LOCATION: [Non-structural protein 1]: Secreted. Host endoplasmic reticulum membrane; Peripheral membrane protein; Lumenal side. Note=Located in RE-derived vesicles hosting the replication complex. SUBCELLULAR LOCATION: [Non-structural protein 2A]: Host endoplasmic reticulum membrane; Multi-pass membrane protein. SUBCELLULAR LOCATION: [Serine protease subunit NS2B]: Host endoplasmic reticulum membrane; Multi-pass membrane protein. SUBCELLULAR LOCATION: [Serine protease NS3]: Host endoplasmic reticulum membrane; Peripheral membrane protein; Cytoplasmic side.
