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.

textAt the nuclear pore, NXF1 (TAP) bound to NXT1 (p15) receives the viral mRNA from the TREX adaptor ALYREF through a mutually exclusive handover: NXF1 binding to ALYREF displaces RNA from ALYREF because the ALYREF N-terminal arginine-rich peptide (residues 16–36, with R29/R30 critical) overlaps the ALYREF RNA-binding surface, while RNA cross-linking to NXF1 via its arginine-rich N-terminal RBD is concomitantly enhanced ~4-fold, as shown by in vitro UV-cross-linking, EMSA, GST-pulldown reconstitutions and in vivo NXF1-overexpression competition assays (Hautbergue et al. 2008). NXF1:NXT1 then engages nucleoporin FG repeats to translocate the mRNA to the cytoplasm, whiIe ALYREF and the rest of TREX are released back into the nucleoplasm (Hautbergue et al. 2008).
