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. Among its related pathways are PI-3K cascade and PI-3K cascade. GO annotations related to this gene include phospholipid binding 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)
