UniProt functional annotation for P11079

UniProt code: P11079.

Organism:		Reovirus type 3 (strain Dearing) (T3D) (Mammalian orthoreovirus 3).
Taxonomy:		Viruses; Riboviria; Orthornavirae; Duplornaviricota; Resentoviricetes; Reovirales; Reoviridae; Spinareovirinae; Orthoreovirus.
Function:		Outer capsid protein involved in mRNA capping. Catalyzes the last 3 enzymatic activities for formation of the 5' cap structure on the viral plus-strand transcripts, namely the RNA guanylyltransferase, RNA-7N- and RNA-2'O-methyltransferase activities.
Catalytic activity:		Reaction=a 5'-end diphospho-ribonucleoside in mRNA + GTP + H(+) = a 5'- end (5'-triphosphoguanosine)-(ribonucleoside) in mRNA + diphosphate; Xref=Rhea:RHEA:67012, Rhea:RHEA-COMP:17165, Rhea:RHEA-COMP:17166, ChEBI:CHEBI:15378, ChEBI:CHEBI:33019, ChEBI:CHEBI:37565, ChEBI:CHEBI:167616, ChEBI:CHEBI:167617; EC=2.7.7.50;
Catalytic activity:		Reaction=a 5'-end (5'-triphosphoguanosine)-(ribonucleoside) in mRNA + S-adenosyl-L-methionine = a 5'-end (N(7)-methyl 5'- triphosphoguanosine)-ribonucleoside in mRNA + S-adenosyl-L- homocysteine; Xref=Rhea:RHEA:67008, Rhea:RHEA-COMP:17166, Rhea:RHEA- COMP:17167, ChEBI:CHEBI:57856, ChEBI:CHEBI:59789, ChEBI:CHEBI:156461, ChEBI:CHEBI:167617; EC=2.1.1.56;
Subunit:		Interacts with protein mu-NS; in viral inclusions. {ECO:0000250}.
Subcellular location:		Virion {ECO:0000305}.
Similarity:		Belongs to the orthoreovirus lambda-2 protein family. {ECO:0000305}.
