GRB2-associated-binding protein 1 is a protein that in humans is encoded by the GAB1 gene.[1]

The protein encoded by this gene is a member of the IRS1-like multisubstrate docking protein family. The encoded protein 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.[2]

Interactions[edit]

GAB1 has been shown to interact with Grb2,[1][3][4] PIK3R1,[1][5][6] PTPN11,[6][7] CRKL,[8] PLCG1[1][9] and MAP3K3.[10] The expression of GAB1 was shown to be regulated by non-coding RNA (miRNA) termed miR-150. [11]
