Rotavirus A (strain RVA/Human/United States/P/1974/G3P1A[8]) (RV-A)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Plays an important role in stimulating the translation of viral mRNAs. These mRNAs are capped but not polyadenylated, instead terminating in a conserved sequence 'GACC' at the 3' that is recognized by NSP3, which competes with host PABPC1 for EIF4G1 binding. The interaction between NSP3 and host EIF4G1 stabilizes the EIF4E-EIF4G1 interaction, thereby facilitating the initiation of capped mRNA translation.UniRule annotation
