NSP5 (nonstructural protein 5) encoded by genome segment 11 of group Arotaviruses. In virus-infected cells NSP5 accumulates in theviroplasms. NSP5 has been shown to be autophosphorylated.[1]Interaction of NSP5 withNSP2 was also demonstrated.[2] Inrotavirus-infected cells, the non-structural proteins NSP5 andNSP2 localize in complexes calledviroplasms, where replication and assembly occur and they can drive the formation of viroplasm-like structures in the absence of other rotaviral proteins and rotavirus replication.[3]
There is no atomic-resolution structure of NSP5 determined as of June 2019. However, the low resolution three-dimensional structure of the NSP2-NSP5 assembly has been observed bycryo-EM. NSP5 occupies the same site as RNA when binding to NSP2. The EM data from this 2006 study has not been published.[4]
