Hello, I am Justin Perdomo soon to be a junior at Kenyon College in Gambier Ohio. I will be a chemistry major and I have an interest in biochemistry. This summer I am working in Dr. Kim’s lab. In the lab, we are working on the reconstitution SLX1-SLX4-PLK1 complex. This complex plays a role in the DNA damage repair process. The first aim is to express and purify the PLK1 protein and SLX4-1632 protein. The second goal is to pull down between the PLK1 and SLX4, USP16, and CHFR proteins. The ultimate goal is to identify new mechanisms of DNA damage response.
