Nucleic acids - protein interactions
2014
2020
The interests of our laboratory lie in understanding protein-nucleic acids interactions that play roles in telomere DNA/chromatin remodeling, non-coding RNA recognition, and bacterial toxin-antitoxin systems’ assembly and functions. We employ biophysical methods that include solution state NMR, CD, fluorescence spectroscopy, X-ray crystallography, isothermal calorimetry, computational analysis, and biochemical assays in our work.
