HER2

Erbb2 (HER2)  belongs to Erbb family lacks the capacity to interact with a ligand because its extracellular region exists in a fixed, unfolded conformation. Erbb2 (HER2) acts as an amplifier of the Erbb signaling network. The adaptors and effector of Erbb2 includes Shc, Syk, RasGAP, Grb2/7, Abl, Mapk8, PLC and STAT1/3. Erbb3 lacks kinase activity and can form heterodimeric complexes with Erbb2. The ERBB2–ERBB3 dimer can be an important cancer therapeutic target.
