GRB2-associated binding protein 1

Gab1, Grb2-associated binder-1
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] (from NCBI)

Papers on Gab1
The signaling adaptor GAB1 regulates cell polarity by acting as a PAR protein scaffold.
Neel et al., Toronto, Canada. In Mol Cell, 2012
The scaffolding adaptor GAB1 interacts with two polarity proteins, PAR1 and PAR3.
Bivalent binding drives the formation of the Grb2-Gab1 signaling complex in a noncooperative manner.
Farooq et al., Miami, United States. In Febs J, 2012

Degradation of the GAB1 adaptor by the ubiquitin-proteasome pathway hampers HGF/SF-MET signaling.
Fafeur et al., Lille, France. In Biochem Biophys Res Commun, 2011
These data demonstrate that GAB1 is ubiquitinated by CBL and degraded by the proteasome, and plays a role in negative-feedback regulation of HGF/SF-MET signaling.
