Working in yeast, Hartwell identified the fundamental role of checkpoints in cell cycle control, and CDC genes such as CDC28, which controls the start of the cycle—the progression through G1.[2]
His earliest publications focused on the isolation of temperature sensitive yeast mutants disabled in basic biological processes, including DNA, RNA and protein synthesis.[10] This led to the identification of the CDC (Cell Division Cycle) genes, which function in promoting the progression through cell division, most notably CDC28, which encodes the yeast Cdk kinase. Other significant discoveries include introduction of the concept of cell cycle "checkpoints", which delay cell division when cellular insults are generated and also the identification and characterization of the mating signal transduction pathway.
Other positions
Hartwell is the Chairman of the Scientific Advisory Board at the Canary Foundation, a non-profit organization dedicated to developing new technologies for the early detection of cancer. He is also a founding co-chair of the Pacific Health Summit, and a member of its executive committee.[11] In September 2009, it was announced that Hartwell would join the faculty of Arizona State University as the Virginia G. Piper Chair of Personalized Medicine and co-director of the Biodesign Institute's Center for Sustainable Health with Dr. Michael Birt.[12][13] He is also adjunct faculty at Amrita University in India.[14]
Lee Hartwell Award
This award is given to scientists whose research in yeast has made the most impact in the broader areas of biology. Recipients of the award also give a lecture at the biennial Yeast Genetics Meeting.[15]
