| Intruduction: | protein encoded by human GRB2-associated-binding protein 1 (GAB1) 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. As an adapter protein, Gab1 plays a role in intracellular signaling cascades triggered by activated receptor-type kinases. It also plays a role in FGFR1 signaling. Probably involved in signaling by the epidermal growth factor receptor (EGFR) and the insulin receptor (INSR), Gab1 can be phosphorylated in response to FGFR1 activation. Gab1 can also be phosphorylated 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. Phosphorylated on tyrosine residues by HCK upon IL6 signaling. Recent data indicated that Gab1 is an essential component of the CCL19/CCR7 chemokine axis that regulates mouse DC migration during asthmatic responses. Full-length human GAB1 cDNA (693aa, Isoform-B) was constructed with codon optimization gene synthesis and expressed with a T7-His-TEV cleavage site Tag (31aa) fusion at N-terminal. This protein was expressed in E. coli as inclusion bodies. The final product was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified. |
