Structural Biology Program
The Christopher Lima Lab
We are a basic research laboratory that studies the structural, biochemical, and functional basis for macromolecules involved in post-translational protein modification by ubiquitin and ubiquitin-like proteins such as SUMO, and pathways that contribute to co- and post-transcriptional RNA maturation, processing and decay. We pursue biochemical approaches to reconstitute key intermediates or complexes in these pathways and combine them with single particle cryo-EM and x-ray crystallography in conjunction with genetics and biochemistry to elucidate structure/activity relationships.

Doctors and faculty members often work with pharmaceutical, device, biotechnology, and life sciences companies, and other organizations outside of MSK, to find safe and effective cancer treatments, to improve patient care, and to educate the health care community.
MSK requires doctors and faculty members to report (“disclose”) the relationships and financial interests they have with external entities. As a commitment to transparency with our community, we make that information available to the public.
