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 | Fanconi anemia (FA) is a rare hereditary disorder characterized by bone marrow failure, compromised genomic stability and increased incidence of cancer. Thirteen complementation groups and genes have been identified, but the exact mechanistic function of many FA proteins remains unclear. FANCD1 is identified as the breast cancer susceptibility protein BRCA2 that is a key regulator of RAD5, having a central role in DNA repair mediated by homologous recombination . FANCD2 becomes monoubiquitinated at K563 in a reaction dependent on the FANCL-E3 ligase domain and localizes to subnuclear foci containing chromatin-associated BRCA1 and RAD51. This event is dependent on the functional FA core complex comprised of eight FA proteins (FANC A/B/C/E/F/G/L/M). Although BRCA2 is not required for ubiquitination, mono-ubiquitinated FANCD2,promotes IR-induced BRCA2 focus formation. Colocalization of FANCD2 and BRCA1along with RAD51 occurs during S phase, in response to double stranded breaks (DSBs) or exposure to drugs like mitomycin C (MMC) that induce DNA interstrand cross links (ICL). Thus the process of monoubiquitination of FANCD2 is an important event that connects the FA phenotype and HR pathways. |
