OverviewAI-generated summary
Kevin D. Raney's research focuses on the mechanisms and functions of helicases and G-quadruplex nucleic acids. He has received significant federal funding from the National Institutes of Health (NIH)/National Institute of General Medical Sciences for two grants totaling over $1.1 million, investigating helicase mechanisms and G-quadruplex signaling. His work has led to a publication record of 131 papers, with approximately 4,896 citations, and an h-index of 45, designating him as a high-impact researcher.
Raney's research group has explored various aspects of helicase activity, including protein displacement by helicase assemblies on single-stranded DNA and the development of fluorescence-based assays for monitoring helicase activity. His publications also include work on Hepatitis C Virus (HCV) nonstructural proteins, specifically NS5A as an RNA-binding protein and NS3 as a multifunctional antiviral target. Additionally, his earlier work investigated the metabolism and toxicity of mycotoxins like aflatoxin B1, including its epoxidation and conjugation with glutathione by human enzymes.
He collaborates with several researchers at the University of Arkansas for Medical Sciences, including John C. Marecki (11 shared publications), Alicia K. Byrd (7 shared publications), and Jun Gao (7 shared publications). Raney also serves as the Department Chairperson for the Department Chairs in the College of Medicine at the University of Arkansas for Medical Sciences.
