  sub:_5 prov:value "The newly identified insulin receptor (IR) substrate, Gab1 [growth factor receptor bound 2 (Grb2)-associated binder-1] is rapidly phosphorylated on several tyrosine residues by the activated IR. Further, we found that Gab1 tyrosine 472 is the major site for association with p85, while tyrosines 447 and 589 are participating in this process. Concerning Gab1/SHP-2 interaction, only mutation of tyrosine 627 prevents binding of Gab1 to SHP-2 SH2 domains, suggesting the occurrence of a monovalent binding event." ;
