Welcome to the David Lab Website!
The David Lab at UC Davis utilizes numerous tools of chemical biology to explore the complex mechanistic details of DNA repair enzymes. DNA repair proteins such as MutY and NEIL, among the targets of research of the David Lab, help catalyze necessary repair of oxidative DNA damage, and are critical to maintaining genomic integrity in organisms living in the oxygen-rich environment of Earth. The David Lab is headed by Dr. Sheila S. David, who has led at the forefront of DNA repair research for the last 30 years. The David Lab continues to push forward the world’s current understanding of DNA repair enzymes by leveraging our unique expertise in DNA repair enzymology while venturing into new areas and collaborating with scientists around the world.

Structural snapshots of base excision by the cancer-associated variant MutY N146S reveal a retaining mechanism
Nucleic Acids Research
“We captured structural snapshots of N146S Geobacillus stearothermophilus MutY bound to DNA containing a substrate, a transition state analog and enzyme-catalyzed abasic site products to provide insight into the base excision mechanism of MutY and the role of Asn.”

How to efficiently pour column fractions: Run a column <60 min.
Doing this will greatly increase your already-existing love of columns. And your productivity.
Get the most out of your flash column. It’s not called slow column chromatography.

A tribute to Jongchan Yeo, you are dearly missed.
Jongchan Yeo was a cherished member of the lab. He received his PhD in Chemistry in 2014 and went on to attend UC Berkeley for his post-doctoral training. He is pictured with Sheila David in his bright pink shirt that he wore while at the library for his students to find him (left) and presenting his research poster at EMGS (right). Thank you for all of your hard work.
His work from our lab has been published in Biochemistry.
