Function

Acts as a translational repressor of viral replicase synthesis late in infection. This latter function is the result of capsid protein interaction with an RNA hairpin which contains the replicase ribosome-binding site.

Biological Context

Subcellular Location: Virion

Virion

Subunit

Homodimer (PubMed:16531233). The homodimers binds to the viral RNA via an operator hairpin, but also to many other RNA sequences in the viral genome; this interaction probably shifts the virus from the replicative to the assembly phase and ensures specific encapsidation of the viral genome (PubMed:16531233, PubMed:8943226). Interacts with the maturation protein A2 (PubMed:28111107, PubMed:29078304)
