NSP2 (NonStructural Protein 2) oktamer, Human rotavirus.

NSP2, is a rotavirus nonstructural RNA-binding protein that accumulates in cytoplasmic inclusions (viroplasms) and is required for genome replication.[1] NSP2 is closely associated in vivo with the viral replicase.[2] The non-structural protein NSP5 plays a role in the structure of viroplasms mediated by its interaction with NSP2.[3]
