Preparation and Storage

Background: GRB2

GRB2 (growth factor receptor-bound 2; also Ash) is a ubiquitously-expressed, 27 kDa member of the GRB2/sem-5 family of adaptor molecules.  It serves as a linker for many intracellular proteins.  Upon BCR ligation, LAB is phosphorylated, binds to GRB2, which subsequently recruits signaling factors.  Upon InsR ligation, GRB2 binds to phosphorylated IRS-1, and serves as a linker to ras-activation.  Human GRB2 is 217 amino acids (aa) in length.  It contains one N-terminal SH3 domain (aa 3-54), a central SH2 domain (aa 60-152), and a C-terminal SH3 domain (aa 160-212).  SH2 domains bind phosphotyrosine motifs; SH3 domains bind proline-rich regions.  There is one splice form that shows a deletion of aa 60-100.  This removes the SH2 domain and initiates apoptosis.  Human GRB2 is over 99% aa identical to mouse and dog GRB2.
