Studying centrosomal complexes using X-ray crystallography, NMR, EM, or biochemistry/cell biology
Investigating the structure and function of centrosomal protein complexes using X-ray crystallography, NMR, EM, or biochemistry/cell biological approaches including single molecule super-resolution imaging
Position Description: We are mainly interested in understanding the structural basis of how various centrosomal protein complexes are generated and how these complexes work together to form a macroscale self-assembly with distinct cellular functions. Recently, we found that Polo-like kinases (Plk4 and Plk1) form high M.W. complexes with diverse binding targets. Tight regulation of the formation of these complexes appears to be critically required for the prevention of cancer development in humans. Thus, we aim to investigate the molecular mechanisms of how these complexes are formed and how they further interact with one another to generate a higher-order assembly and promote cellular processes central for cell cycle progression, proliferation and tumorigenesis.
Fellows who have an expertise in either 1) X-ray crystallography or NMR with an interest in learning various electron microscopy applications at NIH facilities or 2) classical cell biology and biochemistry with an interest in various super-resolution imaging approaches are encouraged to apply.
Applicants should have a Ph.D. (or expected to receive a Ph.D.) or M.D. equivalent at the time of joining the lab or have achieved the degree less than 3 years ago. For additional information, please click the link below.
To apply, please send CV and three names of references to Dr. Kyung Lee (firstname.lastname@example.org).
