Job DescriptionThe Nolen laboratory at the University of Oregon (https://blogs.uoregon.edu/nolenlab/) seeks a highly motivated postdoctoral researcher to join our lab full time on a flexible start date. Our interest is in understanding the molecular basis for the regulation of the actin cytoskeleton. We apply a broad range of techniques to understand the structure-function relationships of actin regulatory proteins and how their molecular mechanisms dictate cellular function. Example of current projects include:
1. Dissection of the mechanism and regulation of the WISH/DIP/SPIN90 (WDS) family proteins.
Approaches used in this project include (but are not limited to) single molecule TIRF microscopy and ensemble methods to determine biochemical mechanism of WDS proteins, x-ray crystallography to determine high resolution structures of WDS family proteins bound to Arp2/3 complex, yeast genetics and live cell imaging combined with structure-function analyses to understand how WDS proteins function in assembly of branched actin networks during endocytosis, and biochemical reconstitution of branched actin network initiation and propagation.
2. Mechanism of Arp2/3 complex regulation.
Approaches used in this project include (but are not limited to) x-ray or electron microscopy to determine high-resolution structures of Arp2/3 complex with bound regulators, single molecule TIRF microscopy and ensemble methods to determine mechanisms of branching nucleation, development of new biochemical/biophysical/optogenetic tools to explore the conformational and kinetic pathway to branching nucleation, and structure-based mutational analysis to test biochemical mechanisms in vitro and in yeast.
Successful candidates will have a Ph.D. in biochemistry, biophysics, structural or cellular biology or a related field, a published record of accomplishment, and good written and oral communication skills.
