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.

textIn the nucleus, cellular retinoic acid binding protein 2 (CRABP2), bound to all trans retinoic acid (atRA), directly binds to heterodimeric nuclear retinoic acid receptors (RAR:RXR) to form a complex through which atRA is channeled from the binding protein to RAR (Majumdar et al. 2011). The RAR:RXR heterodimer can be formed between any of three receptor isoforms for each; RARA, RARB, or RARG with RXRA, RXRB, or RXRG (Neiderreither and Dolle 2008). RARA requires sumoylation and phosphorylation for ligand binding and nuclear localisation (Zhu et al. 2009, Santos & Kim 2010).

RAR:RXR bind to their RA response elements (RARE, composed of tandem direct repeats of 5'-AGGTCA-3' spaced by either 2 bp or 5 bp (DR2, DR5) in response to their physiological ligand atRA, and regulate gene expression in various biological processes.
