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 | One of the three domains in disabled homolog 1 (DAB1) is a tyrosine-rich region consists of five highly conserved tyrosine residues; Y185, Y198, Y200, Y220 and Y232. These residues correspond to two consensus Src family kinase recognition sites (YQxI, Y185 and Y198) and two consensus Abl/Crk recognition sites (YxVP, Y220 and Y232). At least three of the tyrosine residues (Y198, Y220 and Y232) can be phosphorylated by the Src kinase family member, tyrosine protein kinase fyn (FYN) in response to Reelin (RELN) stimulation (Katyal et al. 2007). Tyrosine-phosphorylated DAB1 acts as a hub to recruit different Src homology 2 (SH2) domain-containing proteins, including the p85 regulatory subunit of phosphatidylinositide-3-kinase (PI3K), cellular adaptors CrkL, Crk, Nck-beta and SOCS (suppressor of cytokine signaling) (Gao & Godbout 2013). Tyrosine phosphorylation of DAB1 also appears to strengthen the association of DAB1 with SH3KBP1 (aka CIN85), an adaptor protein involved in endocytic down-regulation of receptor-tyrosine kinases (Fuchigami et al. 2013). |
