Drs. Justin Du Bois (Chemistry) and Alan Pao (Medicine) are collaborators on this work. NSF MCB Maduke (PI) 07/01/10 06/30/14 Probing Conformational Change in a Cl - /H + Antiporter of known Structure The goal of this project is to use 19 F NMR to examine conformational changes in CLC-ec1. NIH PAR Perozo (PI) 08/01/10-07/31/15 Membrane Protein Structural Dynamics Consortium The Membrane Protein Structural Dynamics Consortium is organized around multidisciplinary project teams and Core Facilities focused on elucidating the relationship between structure, dynamics and function in a variety of membrane proteins. The resources developed by the Core Facilities are being made available to the broader community. I lead a project within the Consortium to develop studies of CLC structural dynamics in collaboration with Drs. Emad Tajkhorshid (University of Illlinois) and Hassane Mchaourab (Vanderbilt University). Role: Co-PI NIH 1 R21 NS Maduke (PI) 09/01/11 04/30/14 The mechanistic basis of non-invasive deep brain stimulation by ultrasound. This project involves investigating the molecular basis for activation of membranes and ion channels by ultrasound. The results will provide a quantitative framework for developing focused ultrasound as a non-invasive tool for experimental and therapeutic deep brain stimulation. AHA 1GRNT Maduke (PI) 07/01/13 06/30/15 Developing small-molecule inhibitors of the CLC-Ka chloride channel In this project, we will characterize the inhibitor-binding site of a novel CLC-Ka inhibitor and will use a chemical-design strategy to evolve next-generation inhibitors.

AHA 10GRNT Maduke (PI) 07/01/10-06/30/12 Improving Selectivity of CLC-K Chloride-channel Inhibitors In this project, we used a structure-based approach to develop and characterize specific inhibitors of CLC channels and transporters, for which the pharmacology is poorly developed. The first molecule we developed is the only known inhibitor of the CLC antiporters (Howery et al., 2012). Our identification of the inhibitor binding site is important for development and refinement of next-generation CLC inhibitors. The second molecule we developed, BIM1, has unprecedented specificity for CLC-Ka over CLC-Kb. NIH R01 GM Maduke (PI) 08/01/05-10/31/10 Mechanisms of CLC Chloride-transport Proteins The goal of this project is to perform mechanistic studies on CLC-ec1, a chloride-proton antiporter, and CLC-0, a chloride channel, in order to better understand the mechanisms of these proteins as well as the functional relationships between channels and transporters. NIH R01 GM S1 Maduke (PI) 09/15/09-07/31/10 Mechanisms of CLC Chloride-transport Proteins The goal of this supplement for the parent grant described above is to enhance our progress towards determining the molecular basis for inhibitor binding to CLC-ec1.
