Postdoctoral Position – Determining the Function of O-GlcNAc Protein 
Modification in Signal Transduction

Department of Plant Biology
University of Minnesota
Olszewski Laboratory

An NSF-funded postdoctoral position studying the function of 
post-translational O-GlcNAc modification of Arabidopsis thaliana 
proteins that is renewable for up to three years is available in 
September 2005.

In addition to being essential, O-GlcNAc modification of cytosolic and 
nuclear proteins is involved in several plant signaling pathways. My 
laboratory has recently obtained evidence that a DELLA protein 
component of the gibberellin signaling pathway is modified by 
arabidopsis O-GlcNAc transferase and hypothesize that this modification 
regulates DELLA protein activity. The postdoctoral hired for this 
position will work with other lab members to test this hypothesis by 
characterizing the signaling activity of non-modifiable mutant DELLA 
proteins. Knowledge of the identities of the O-GlcNAc modified proteins 
is extremely limited and the postdoctoral will address this deficiency 
using mass spectrometry based approaches to identify O-GlcNAc modified 

Applicants should have a Ph.D. with experience in protein biochemistry, 
molecular biology or hormone signaling. Applicants should send a CV, a 
cover letter outlining his or her research experience and career goals, 
and arrange to have two letters of reference sent to: Neil Olszewski, 
Department of Plant Biology, University of Minnesota, 1445 Gortner 
Ave., St. Paul, MN 55108 USA. Contact by e-mail is preferred 
(neil at cbs.umn.edu).
