Summary

This picture illustrates the mechanism in which EGFR, HER3, and HER4 change conformation in order to dimerize and activate further cell signaling. A) Sub-domain I (green) is sepearated from sub-domain III (blue). Sub-domain II (red) forms an interaction (purple line) with sub-domain IV (yellow). This conformation allows sub-domain II to be hidden and unavailable for dimerization. B) The interaction between sub-domain II and sub-domain IV can be temporarily broken allowing for the receptor to become more available for ligand-binding. C) Upon ligand-binding, if the interaction of sub-domain II and IV is still formed, the interaction between sub-domain II and sub-domain IV is broken and allows sub-domain II to become available for homo- or hetero-dimerization with another receptor from the HER family.
