GRB2-associated-binding protein 2 is a protein that in humans is encoded by the GAB2 gene.[1][2][3]

The protein encoded by this gene, GAB2 is an adaptor protein serving as principal activator of Phosphatidylinositol 3-kinase. 10 SNPs of GAB2 gene have been found in one study to associate with risk of Alzheimer's disease in the carriers of ApoE4 allele.[4]

Interactions

GAB2 has been shown to interact with PTPN11,[1][5][6][7] PLCG2,[5] RICS,[8] Grb2,[1][6][9] PIK3R1,[6][7] CRKL,[7] AKT1[6] and SHC1.[5][6]
