Biography

Dr. Wang conducted his graduate work on structure determination of fragments of 23S rRNA using NMR spectroscopy and UV-melting experiments in Professor David E. Draper's lab of the Johns Hopkins University. Dr. Wang received his Ph.D. in October 1994 from the Johns Hopkins University. From 1994 to 2000 he was an NIH postdoctoral later a research fellow in Dr. Dennis Torchia's laboratory where he studied the structure, hydration dynamics of HIV-1 protease in complex with inhibitors and elucidated the 3D structure and a new function of the antitumor/anti-HIV protein MAP30. In the late 2000 he then joined the Structural Biophysics Laboratory of NCI. Using high field NMR spectroscopy and other biophysical and biochemical methods, his group studies the functional structural biology of RNAs and proteins.

Research

The long term research interests of Dr. Wang's laboratory are to understand the fundamental interactions regulating essential events involving RNA in the translational and post-translational processes on both the structural and cellular levels using NMR spectroscopy and various other biophysical, biochemical, and biological methods.
Currently, the lab focuses on the key structural element(s) in 3' and 5' prime UTR RNAs that are important for gene regulation. My lab is studying the structural basis of an adenine riboswitch, which regulates the gene expression in response to the level of adenine as a metabolite. This riboswitch is located in the 5' end of bacterial mRNA. The structural knowledge of the switching may be important to understand the fundamental mechanism of regulation of gene expression by RNA regulators.
Researchers in Wang's laboratory are also engaged in developing new methods and technologies to achieve research objectives.
Wang's laboratory has been at forefront of using small angle X-ray scattering (SAXS) to study structures and dynamics of RNAs and proteins. His laboratory has established the CCR SAXS Core facility, which is open to all intramural and extramural research communities. For the past four years, more than 80 laboratories and research groups from US and other countries have used the CCR SAXS resources.
