Query author contributions in Reactome

Reactome depends on collaboration between our curation team and outside experts to assemble and peer-review its pathway modules. The integration of ORCID within Reactome enables us to meet a key challenge with authoring, curating and reviewing biological information by incentivizing and crediting the external experts that contribute their expertise and time to the Reactome curation process. More information is available at ORCID and Reactome.

If you have an ORCID ID that is not listed on this page, please forward this information to us and we will update your Reactome pathway records.

Cytosolic dispersed NSP2 is phosphorylated at S313 by casein kinase CK1alpha. There is evidence from the simian rotavirus strain SA11-4F that NSP2 gets hyperphosphorylated, either through autophosphorylation or by CK1alpha (Criglar et al, 2018).

Proteins from the simian rotavirus SA11 strains are commonly used in experiments resulting in general claims about rotavirus A strains. However, the SA11 NSP2 can be of genotype N2 or N5, while NSP2 from human strains can be of genotypes N1, N2, or N3 (Matthijnssens et al, 2008). Still, alignment of human Wa strain and SA11 NSP2 sequences show the same S313 residue and an overall 90% aa identity.
