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.

commentFUNCTION Sequence-specific transcription factor which is part of a developmental regulatory system that provides cells with specific positional identities on the anterior-posterior axis. Required for induction of SELE/E-selectin and VCAM1 on the endothelial cells surface at sites of inflammation (PubMed:22269951). Positively regulates EIF4E-mediated mRNA nuclear export and also increases the translation efficiency of ODC mRNA in the cytoplasm by competing with factors which repress EIF4E activity such as PRH (By similarity).SUBUNIT Transiently interacts with PRMT5 in TNF stimulated endothelial cells (PubMed:22269951). Interacts with EIF4E (By similarity).INTERACTION Methylated on Arg-140 by PRMT5; methylation is critical for E-selectin induction.DISEASE A chromosomal aberration involving HOXA9 is found in a form of acute myeloid leukemia. Translocation t(7;11)(p15;p15) with NUP98 (PubMed:8563753). The chimera includes NUP98 intrinsic disordered regions which contribute to aberrant liquid-liquid phase separation puncta of the chimera in the nucleus. This phase-separation enhances the chimera genomic targeting and induces organization of aberrant three-dimensional chromatin structures leading to tumourous transformation (PubMed:34163069).DISEASE A chromosomal aberration involving HOXA9 may contribute to disease progression in chronic myeloid leukemia. Translocation t(7;17)(p15;q23) with MSI2.SIMILARITY Belongs to the Abd-B homeobox family.
