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.

textGlycoproteins in human tumors often exhibit abnormal glycosylation patters, e.g. certain Lewis structures, TF antigen, Tn antigen and/or their sialylated forms, which creates additional binding sites for glycoreceptors. The C-type lectin domain family 10 member A (CLEC10A/MGL/CD301) is a calcium-type (C-type) lectin glycoreceptor expressed on dendritic cells (DCs) (Suzuki et al. 1996). It recognizes glycoproteins from both altered self and pathogens due to its monosaccharide specificity for galactose (Gal) and N-acetylgalactosamine (GalNAc). CLEC10A specifically binds glycans with terminal GalNAc residues such as Tn antigen (GalNAcalpha-serine/threonine), 6-sulfo-Tn, Lac-di-NAc (Galbeta1,4-GlcNAc) as well as core 5 (GalNAcalpha1-3GalNAcalpha-) and core 6 (GlcNAcbeta1-6GalNAcalpha-) that are expressed in human tumors (Mortezai et al. 2013, van Vliet et al. 2005). CLEC10A on immature human monocyte-derived DCs has been shown to recognize and internalize the three tandem repeat peptides of Mucin-1 carrying Tn (Tn-MUC1) (Denda-Nagai et al. 2010).
