Summaries for GAB1 Gene

Entrez Gene Summary for GAB1 Gene

  • The protein encoded by this gene is a member of the IRS1-like multisubstrate docking protein family. It is an important mediator of branching tubulogenesis and plays a central role in cellular growth response, transformation and apoptosis. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2008]

GeneCards Summary for GAB1 Gene

GAB1 (GRB2 Associated Binding Protein 1) is a Protein Coding gene. Diseases associated with GAB1 include Leopard Syndrome and Noonan Syndrome 1. Among its related pathways are MET promotes cell motility and RET signaling. Gene Ontology (GO) annotations related to this gene include signal transducer activity and SH3/SH2 adaptor activity. An important paralog of this gene is GAB2.

UniProtKB/Swiss-Prot for GAB1 Gene

  • 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).
