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.

textRET has been shown to bind GRB2 directly, via Tyrosine-1096 (Y1096) (Alberti et al. 1998, Besset et al. 2000). GRB2 is found in a complex with SOS1 in unstimulated cells (Hayashi et al. 2000).

GDNF stimulation of neuronal cells induces the assembly of a large protein complex containing RET, GRB2 and tyrosine-phosphorylated SHC1, p85 subunit of (PI3K), GAB2 (GAB1 in Hayashi et al. 2000) and Tyrosine-protein phosphatase non-receptor type 11 (PTPN11, SHP-2) (Besset et al. 2000). This suggests that at least two distinct RET-SHC1 protein complexes can assemble via phosphorylated Y1062, one involving GRB2 and SOS1 leads to activation of the RAS-RAF-ERK pathway, another involving GRB2, GAB2 and p85 leads to the PI3K-AKT pathway. This latter complex can also assemble directly onto phosphorylated Y1096 (Besset et al. 2000).

RET can activate the RAS-RAF-ERK signaling pathway (van Weering et al. 1995, Ohiwa et al. 1997, van Weering & Bos 1997, Trupp et al. 1999, Hayashi et al. 2000). RAS signaling is markedly impaired by mutations of RET Y1062 (Hayashi et al. 2000). RET RAS signaling and the effect of the Y1062 mutation are believed to be mediated by RET complexes involving GRB2:SOS1, well known as mediators of signaling to RAS in other receptor systems (Ravichandran 2001).
