Figure 1. Ribbon Diagrams of ErbB4 Kinase Structures
(A) The active conformation of the ErbB4 kinase. The activation loop is colored red.
(B) An inactive conformation of the ErbB4 kinase in complex with lapatinib, which is shown as a red stick model. The activation loop is disordered, but the loop termini are colored red.
(C) Superposition of the active and inactive conformations of the ErbB4 kinase.
