What is the function of this protein?
Plays a role in viral transcription/replication and prevents the simultaneous activation of host cell dsRNA sensors, such as MDA5/IFIH1, OAS, and PKR (By similarity).  Acts by degrading the 5'-polyuridines generated during replication of the poly(A) region of viral genomic and subgenomic RNAs.  Catalyzes a two-step reaction in which a 2'3'-cyclic phosphate (2'3'-cP) is first generated by 2'-O transesterification, which is then hydrolyzed to a 3'-phosphate (3'-P) (By similarity).  If not degraded, poly(U) RNA would hybridize with poly(A) RNA tails and activate host dsRNA sensors (By similarity).
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?
[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. 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 10]: 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: [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: [Uridylate-specific endoribonuclease]: Host cytoplasm, host perinuclear region.
