Challenges prior models of NSP3 as essential for rotavirus translation; leaves open its in vivo role and therapeutic potential.
Contrary to previous beliefs, rotavirus nonstructural protein NSP3 is neither required for the translation of viral mRNAs nor essential for virus replication in cell culture.
Montero et al. (2006) studied Rotavirus infection. NSP3 gene silencing via siRNA vs. Irrelevant siRNA (siRNA IRR) was evaluated on Viral protein synthesis and viral progeny yield. Silencing the expression of rotavirus nonstructural protein NSP3 did not decrease viral protein synthesis, but restored cellular protein synthesis and increased the yield of viral progeny.
