The Heeseon An Lab
Human cells orchestrate up to ~20,687 proteins to maintain cell growth and survival. Upon environmental change, cells dynamically remodel their proteomic landscape by two simultaneous processes: enhancing the synthesis of proteins that respond to the altered cellular conditions and degrading a subset of the pre-existing proteome. Any defect in this nature’s fine-tuned system hampers regulated cell growth as exemplified by cancer and neurodegenerative disorders. To fully understand the underlying pathology of the dysregulated proteostasis system, Heeseon An’s lab studies the regulatory mechanisms of protein translation and degradation processes in health and disease. Importantly, we develop chemical, biological, and proteomics tools to enable quantitative analyses of the cell biological events.

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.
Heeseon An discloses the following relationships and financial interests:
