Ilya Finkelstein's profile
What I do
Our cells are constantly subjected to intracellular and extracellular stresses that threaten genomic fidelity. Double strand breaks (DSB) in DNA are a form of damage that may arise spontaneously during DNA replication or as a result of external factors such as ionizing radiation or chemical damaging agents. Upon sensing DSB, the cell initiates a host of responses that identify, encapsulate, and ultimately process the damaged site. The goal of my work is to directly visualize the behavior of several key proteins that participate in DSB repair. Fluorescence and biochemical assays will probe the mechanism of protein-DNA association and observed nuclease activity of the complex in the context of DNA binding.
