Crk and Grb2 family adaptor proteins are involved in a variety of cell signaling pathways related to human diseases. These adaptors have Src homology 2 (SH2) and Src homology 3 (SH3) domains, which are docking sites for several signaling proteins, including receptors, kinases, and GTPase regulators. In addItion, other protein-protein interactions may also utilize Crk and Grb2 domain interactions to modulate cell signaling pathways. The DOCK family of proteins (DOCK3, DOCK4, and DOCK5) can interact with Crk and may be important Crk effector proteins. The cell cycle regulator p27Kip1 can interact with Grb2, and this implicates Grb2 activity in cell signaling pathways that alter cell cycle progression.

Western blot of rat PC12 cell lysate. The blot was probed with mouse monoclonal anti-Grb2 antibody at 1:250 (lane 1), 1:500 (lane 2), or 1:1000 (lane 3).

Immunocytochemical labeling of Grb2 in rat PC12 cells differentiated with NGF. The cells were labeled with mouse monoclonal Grb2 (GM3311) antibody, then detected using appropriate secondary antibody conjugated to Cy3.

Clone (M331) was generated from a full length recombinant rat Grb2 protein. This sequence has high homology to human and mouse Grb2.
