## Abstract

PROJECT SUMMARY
 DNA helicases function in virtually all aspects of DNA replication, recombination, and repair. As such,
they are vital to maintaining genome integrity and are disease linked when mutated. Despite many in vivo and
in vitro advances in working with helicases, there is a gap in knowledge connecting mutant alleles of helicase
genes to the treatment of patients in clinics. The objective of my research is to gain mechanistic insight into
how DNA helicases function in genome maintenance and why their dysfunction leads to disease. Toward this
goal, we are studying PIF1 and RecQ family helicases, which are evolutionarily conserved and because
mutations in the human genes encoding these helicases are associated with multiple diseases. Our current
work focuses on the roles of RecQ helicases in DNA inter-strand crosslink (ICL) repair and RecQ and Pif1
helicases in telomere maintenance. To perform this work, we will employ a variety of classic and cutting edge
experimental techniques, from standard in vitro enzymatic assays and model organism genetics to next-
generation sequencing, crosslinking mass spectrometry, and the development of custom click chemistry
probes. Overall, this work will provide fundamental data critical to understanding how PIF1 and RecQ family
helicases aid in the maintenance of genome stability, and it will ultimately lead to therapeutic targets and
treatments for helicase-linked diseases.
