OverviewAI-generated summary
Amit Ketkar's research focuses on DNA repair mechanisms and the function of specialized DNA polymerases, particularly in the context of human health and disease. His work investigates how these polymerases interact with DNA structures, such as G-quadruplexes, and how they contribute to processes like translesion DNA synthesis. Ketkar has examined the role of specific protein motifs, like the insert-2 region in human Rev1, in mediating selective binding to these DNA structures and promoting accurate replication. His research also explores the implications of DNA polymerase activity in cancer, specifically in glioblastoma, by investigating how these enzymes act as barriers to replication or influence genomic instability. Ketkar has published findings on the inhibition of key enzymes, such as tryptophan 2,3-dioxygenase, and their impact on DNA damage tolerance and repair in glioma cells. His scholarship metrics include an h-index of 19 with 42 total publications and 826 total citations.
