General annotation (Comments)

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

GTP + (5')pp-Pur-mRNA = diphosphate + G(5')ppp-Pur-mRNA.

S-adenosyl-L-methionine + G(5')pppR-RNA = S-adenosyl-L-homocysteine + m7G(5')pppR-RNA.

Subunit structure

Interacts with protein mu-NS; in viral inclusions By similarity.

Subcellular location

Virion Potential.

Sequence similarities

Belongs to the orthoreovirus lambda-2 protein family.
