Polo Kinase in Mitotic Controls and Tumorigenesis

Dr. Kyung Lee

A postdoctoral fellowship is available to study the function of mammalian polo-like kinase 1 (Plk1) and its interacting proteins in normal and cancer cell proliferation. Plk1 plays a pivotal role in proper mitotic progression and its deregulation is tightly associated with oncogenesis. We have been studying various centrosomal and kinetochore proteins that are critical for both subcellular localization and mitotic/non-mitotic functions of Plk1. Projects include, but are not limited to, the mechanisms of various Plk1-mediated cellular events and the physiological significance of Plk1 and its associated proteins during cell cycle progression, tumorigenesis, and stem cell proliferation.

Applicants should be a Ph.D. or M.D. with less than 3 years of postdoctoral experience. Expertise in cell biology, biochemistry, and stem biology is preferred. Visit https://ccrod.cancer.gov/confluence/display/CCRKLEE/Home for additional information. Salary starts at $49,400 plus health insurance with no previous postdoctoral training. To apply, send CV to Dr. Kyung Lee (kyunglee@mail.nih.gov). This position is subject to a background investigation.
