General annotation (Comments)

Function

Inner capsid (core) component. Displays NTPase, RNA 5'-triphosphatase (RTPase) and RNA helicase activities and probably participates in transcription of the viral genome. Helicase activity might be involved in unwinding or reannealing dsRNA during RNA synthesis. RTPase enzymatic activity represents the first step in RNA capping, which yields a 5'-diphosphorylated plus-strand RNA.

Catalytic activity

ATP + H2O = ADP + phosphate.

Cofactor

Magnesium or manganese.

Subunit structure

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

Subcellular location

Virion Potential. Note: Found in the inner capsid (120 copies).

Sequence similarities

Belongs to the orthoreovirus lambda-1 protein family.

Contains 1 C2H2-type zinc finger.

Sequence caution

The sequence AAA47271.1 differs from that shown. Reason: Frameshift at positions 1206 and 1259.
