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.

| text | Nef has been shown to bind specifically to a subset of the Src family of kinases. Nef/Fyn interaction centers on a proline-rich motif (Pro-x-x-Pro), which is implicated in SH3 binding. This domain is partially disordered in the absence of the binding partner; when bound this motif fully adopts a left-handed polyproline type II helix conformation upon complex formation with the Fyn SH3 domain. Within this structure the arginine residue (Arg77) of Nef interacts with Asp 100 of the RT loop within the Fyn SH3 domain, and triggers a hydrogen-bond rearrangement which allows the loop to adapt to complement the Nef surface. The Arg96 residue of the Fyn SH3 domain is specifically accommodated in the same hydrophobic pocket of Nef. The Nef-Fyn complex forms in vivo and may have a crucial role in the T cell perturbating action of Nef by altering T cell receptor signaling. |
