FunctionProbably involved in EGF and insulin receptor signaling.
Sequence similaritiesBelongs to the GAB family. Contains 1 PH domain.
Post-translational modificationsPhosphorylated 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.
Flow cytometry analysis of HeLa (human cervix adenocarcinoma) cells labeling GAB1 (red) with ab32093 at a 1/2500 dilution. Cells were fixed with 4% paraformaldehyde and permeabilized with 90% methanol. A goat anti-rabbit IgG (Alexa Fluor® 488) (ab150077) was used as the secondary antibody at a 1/2000 dilution. Black - Rabbit monoclonal IgG (ab172730). Blue (unlabeled control) - Cells without incubation with primary and secondary antibodies.
