<!--

~~HER4/ErbB4 is a ubiquitously expressed member of the EGF/ErbB family of receptor tyrosine kinases that is essential for normal development of the heart~~, ~~nervous system~~, ~~and mammary gland. We report here crystal structures of~~ the ~~ErbB4 kinase domain in active and lapatinib-inhibited forms. Active ErbB4 kinase adopts an asymmetric dimer conformation essentially identical~~ to ~~that observed to be important for activation of~~ the ~~EGF receptor~~/~~ErbB1 kinase. Mutagenesis studies of intact ErbB4 in Ba~~/~~F3 cells confirm the importance of this asymmetric dimer for activation of intact ErbB4~~. ~~Lapatinib binds to an inactive form of the ErbB4 kinase in a mode equivalent to its interaction with the EGF receptor~~. ~~All ErbB4 residues contacted by lapatinib are conserved in~~ the ~~EGF receptor and HER2/ErbB2, which lapatinib also targets. These results demonstrate that key elements of kinase activation and inhibition are conserved among ErbB family members~~.
