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.

commentFUNCTION Adapter protein that plays a role in intracellular signaling cascades triggered by activated receptor-type kinases. Plays a role in FGFR1 signaling. Probably involved in signaling by the epidermal growth factor receptor (EGFR) and the insulin receptor (INSR). Involved in the MET/HGF-signaling pathway (PubMed:29408807).SUBUNIT Identified in a complex containing FRS2, GRB2, GAB1, PIK3R1 and SOS1 (By similarity). Forms a tripartite complex containing GAB1, METTL13 and SPRY2 (PubMed:29408807). Within the complex interacts with METTL13 (PubMed:29408807). Interacts with GRB2 and with other SH2-containing proteins (PubMed:15010462). Interacts with phosphorylated LAT2 (PubMed:12486104). Interacts with PTPRJ (PubMed:12475979). Interacts (phosphorylated) with PTPN11 (PubMed:15010462). Interacts with HCK (PubMed:15010462).INTERACTION Phosphorylated in response to FGFR1 activation. Phosphorylated on tyrosine residue(s) by the epidermal growth factor receptor (EGFR) and the insulin receptor (INSR). Tyrosine phosphorylation of GAB1 mediates interaction with several proteins that contain SH2 domains. Phosphorylated on tyrosine residues by HCK upon IL6 signaling.DISEASE The disease is caused by variants affecting the gene represented in this entry.SIMILARITY Belongs to the GAB family.
