Research in the Binder lab focuses on ethylene signal transduction. One areaof research is on the structure and function of the ethylene binding domain. Some of our goals with this are to characterize the ethylene binding pocket and define the conformational changes that occur when ethylene binds to the receptor. Another focus is on the signal output of the receptors. While the receptors have been shown to have protein kinase activity, this activity is not crucial for receptor function. Thus, we are working towards defining the output of the receptors. A third focus is on better defining components down-stream of the receptors and interactions with other hormone signaling pathways. Finally, we are examining the evolution of ethylene receptors. It is believed that these receptors were acquired during the endosymbiotic event that led to chloroplasts. We are now studying putative ethylene receptors in various cyanobacteria. To pursue these projects we combine biochemistry, molecular biology, genetics and physiology.
