Function

function

Plays a role in RNA replication. It is covalently linked to the 5'terminus of both viral single-stranded RNA1 and RNA2 molecules.
Replicates the viral genome.
The protease cofactor and the putative helicase seem to target the replication complexes to ER membranes. Their physical association causes the membrane rearrangement of host ER that may result in formation of the small membranous vesicles that are the site of viral RNA synthesis.
Thiol protease that cleaves the RNA1 and RNA2 polyproteins.
