GRB7 Polyclonal Antibody, AbBy Fluor™ 555 Conjugated

Many growth factors function by binding receptors with intrinsic tyrosine kinase activity (1,2) . Signaling by such receptors involves a series of intermediates characterized by SH2 domains that bind tyrosine phosphorylated receptors by a direct interaction between the SH2 domain and the phosphotyrosine-containing receptor sequences (3,4) . GRB7, a SH2 domain protein, has a single SH2 domain at its C-terminal, a central region with similarity to Ras GAP and a proline-rich N-terminus (5,6) . GRB7 maps to the region on mouse chromosome 11 containing the Neu gene (6) . This region of mouse chromosome 11 is syntenic to an area of human chromosome 17q that is frequently amplified in breast cancer (6,7) . Moreover, GRB7 is amplified and over-expressed in breast cancer and is found in a complex with Neu gp185 (6) .
