Crystal Structure of C. elegans HER-1
Overview
HER-1 is a secreted protein that promotes male development in the nematode Caenorhabditis elegans. HER-1 inhibits the function of TRA-2A, a multipass integral membrane protein thought to serve as its receptor. We report here the 1.5-A crystal structure of HER-1. The structure was solved by the multiwavelength anomalous diffraction method by using selenomethionyl-substituted HER-1 produced in Chinese hamster ovary cells. The HER-1 structure consists of two all-helical domains and is not closely homologous to any known structure. Sites of amino acid substitutions known to impair HER-1 function were mapped on the HER-1 structure and classified according to the likely mechanism by which they affect HER-1 activity. A subset of these and other amino acid substitutions on the HER-1 surface were assayed for their ability to disrupt interactions between HER-1 and TRA-2A-expressing cells, and a localized region on the HER-1 surface important for mediating this interaction was identified.
