NSP5 (nonstructural protein 5) encoded by genome segment 11 of group A rotaviruses. In virus-infected cells NSP5 accumulates in the viroplasms. NSP5 has been shown to be autophosphorylated.[1] Interaction of NSP5 with NSP2 was also demonstrated.[2] In rotavirus-infected cells, the non-structural proteins NSP5 and NSP2 localize in complexes called viroplasms, 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 by cryo-EM. NSP5 occupies the same site as RNA when binding to NSP2. The EM data from this 2006 study has not been published.[4]
