Abstract: A substantially pure protein, Gab1, that binds to Grb2 is disclosed. Isolated nucleic acid molecules that encode Gab1 is disclosed. Pharmaceutical compositions comprising a pharmaceutically acceptable carrier in combination with nucleic acid molecules are disclosed. Fragments of nucleic acid molecules that encode Gab1 having at least 10 nucleotides and oligonucleotide molecule comprising a nucleotide sequence complimentary to a nucleotide sequence of at least 10 nucleotides are disclosed. Recombinant expression vectors that comprise the nucleic acid molecule that encode Gab1, and host cells that comprise such recombinant vectors are disclosed. Antibodies that bind to an epitope on Gab1 are disclosed. Methods of identifying inhibitors, activators and substrates of Gab1 are disclosed. Antisense compounds and methods of using the same are disclosed.
