You are invited to apply for a postdoctoral position in the structural biology 
lab of McArdle Cancer Institute of University of Wisconsin at Madison. We are 
interested in understanding the structural basis of protein phosphatase 2A 
(PP2A) regulation and its cross-talk to cellular and viral kinases in 
controlling signaling proteins involved in cell cycle, DNA damage response, and 
cell metabolism. One important aspect of the study is to elucidate mechanisms 
of protein chaperones in modulating the function of diverse PP2A complexes, 
kinases and nuclear receptors in response to cellular and environmental signals 
using structural biology techniques in combination of biochemical and 
biophysical methods and cell biology approaches. Initial results of this 
specific aspect of study can be found in our recent publications (Nat. Commun., 
4:1699, 2013; Molecular Cell 41, 1–12, 2011).
 
 
 
The lab is equipped with a state-of-the-art setup for x-ray crystallographic 
studies, including crystallography robot, and have convenient monthly access to 
powerful x-ray beamlines at APS. The researcher will work in a 
multidisciplinary setup, including cell biology, biophysics, proteomics, and 
protein biochemistry, in addition to protein crystallography. 
 
 
 
Candidates should hold a PhD in protein biochemistry and crystallography and 
have a good working knowledge of molecular biology techniques. The candidates 
should be highly motivated, goal-driven, and dedicated individuals who can 
think critically and work both independently and collaboratively with good 
verbal and written communication skills. It is also important that the 
candidates are creative in problem solving and have a strong desire to seek 
answers to questions related to the molecular basis of cellular processes. 
Experience in cell culture techniques and writing scientific research papers 
would be advantageous. Eligibility to training grant is appealing, but not 
essential.
 
 
 
This is a full-time position with a starting salary of $39,264 – 44,340 per 
year depending on skills and experience.
 
 
 
Review of applications will begin immediately and continue until the positions 
are filled.
 
 
 
To apply: Please send a cover letter, CV and the names and contact information 
for three references to Dr. Yongna Xing, 1400 University Avenue, McArdle 
Laboratory for Cancer Research, University of Wisconsin-Madison-Madison, WI 
53706. Email: yx...@oncology.wisc.edu.
