A postdoctoral position is available to study proteins involved in herpesvirus entry, egress, and latency in the Heldwein lab at Tufts University School of Medicine, Boston, MA. Work will involve overexpression of membrane-bound and soluble proteins in eukaryotic cells followed by their crystallization, structure determination, and biochemical analysis. See Chowdary et al. (2010) NSMB, 17,* *882-888 for an example of our recent work. The laboratory is fully equipped for all aspects of molecular biology, biochemistry, protein expression, and has a crystallization robot and an in-house x-ray diffractometer. We also have access to synchrotron facilities at APS and BNL. Applicants should hold a PhD in a biological science, have experience in macromolecular crystallography or other biophysical techniques, and have a good publication record. Experience in membrane protein expression and biophysical characterization is highly desirable. Strong communication skills in oral and written English are essential. To apply, please, send a letter of interest, a CV, and names of 3 references to Dr. Katya Heldwein by e-mail: [log in to unmask]
