ity.18,19 The Abl SH2 domain forms an extensive interaction interface with the C-terminal lobe of the kinase domain that is stabilized by an interlocking network of hydrogen bonds (Fig. 2).18 Due to the different relative orientation of the 2 kinase lobes in Src and Abl, the SH2 domain approaches the kinase domain much closer in Abl (Fig. 2). The SH2âC-
Homodimer and heterodimer formations of ERBB receptors. Receptors are shown as two lobes connected by a transmembrane stretch. Binding of a ligand, neuregulin (NRG, blue square) or something EGF-like to the extracellular lobe activates the receptors. On ErbB1, ErbB3, (note inactive kinase, marked by a cross) or ErbB4 induces homodimer formation.
