Epidermal growth factor receptor (ErbB) family is a class of receptor tyrosine kinases (RTKs) that have a pivotal role in the processes of cell growth, proliferation, and differentiation [1-5]. They exist on the cell surface as dimers in both active and inactive states, which switch between them through conformational changes upon ligand binding. They suffer a strong lateral dimerization that leads to proper assembly of their extracellular ligand-binding, single-span transmembrane, and cytoplasmic kinase domains which is key for ErbB activation. The transmembrane (TM) and juxtamembrane region of these receptors are essential for dimerization and activation [1-5]. This entry represents the TM and juxtamembrane segment of EGFR, ErbB2 and ErbB4.
