Gene
N/A
Organism
Rotavirus A (strain SA11-Ramig G3-Px[x]-Ix-Rx-Cx-Mx-Ax-Nx-Tx-Ex-Hx) (RV-A) (Simian Agent 11 (strain Ramig))
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at protein leveli

Functioni

Involved in genome replication and packaging. Plays a crucial role, together with NSP5, in the formation of virus factories (viroplasms) which are large inclusions in the cytoplasm where replication intermediates are assembled and RNA replication takes place. Displays ssRNA binding, NTPase, RNA triphosphatase (RTPase) and ATP-independent helix-unwinding activity activities. The unwiding activity may prepare and organize plus-strand RNAs for packaging and replication by removing interfering secondary structures. Unlike typical helicases, NSP2 requires neither a divalent cation nor a nucleotide energy source for helix destabilization. The RTPase activity may account for the absence of the 5'-terminal gamma-phosphate on the minus-strands of dsRNA genome segments (By similarity).By similarity

Cofactori
