CC -!- FUNCTION: Plays an important role in stimulating the translation of
CC viral mRNAs. These mRNAs are capped but not polyadenylated, instead
CC terminating in a conserved sequence 'GACC' at the 3' that is recognized
CC by NSP3, which competes with host PABPC1 for EIF4G1 binding. The
CC interaction between NSP3 and host EIF4G1 stabilizes the EIF4E-EIF4G1
CC interaction, thereby facilitating the initiation of capped mRNA
CC translation. {ECO:0000256|HAMAP-Rule:MF_04094}.
CC -!- SUBUNIT: Homodimer. Interacts (via the coiled-coil region) with host
CC ZC3H7B (via LD motif). Interacts with host EIF4G1. {ECO:0000256|HAMAP-
CC Rule:MF_04094}.
CC -!- SUBCELLULAR LOCATION: Host cytoplasm {ECO:0000256|HAMAP-Rule:MF_04094}.
CC -!- SIMILARITY: Belongs to the rotavirus A NSP3 protein family.
CC {ECO:0000256|HAMAP-Rule:MF_04094}.
