Research from the Columbus Lab featured on cover of JACS


Opa proteins are outer membrane proteins in Neisseria meningitidis and Neisseria gonorrhoeae that have flexible extracelullar loops that interact with human receptors. This Opa-receptor interaction triggers the engulfment of the bacterium by human host cells. The cover shows several conformers of these loops extending from the Opa β-barrel which is embedded in a lipid bilayer.

Dan and Ryan honored at the 2012 Robert J. Huskey Research Exhibition

The Huskey Research Exhibition is an annual event which provides a forum for all graduate students in the Graduate School of Arts and Sciences and the School of Architecture to publicize their research. In addition, the event rewards students presenting superior research. The 12th Annual Huskey Research Exhibition occurred on March 21, 2012. This year, Dan Fox and Ryan Oliver received second place in the Physical Science and Mathematics Division. Ryan’s poster was titled “Investigating the relationship between physical properties of detergents and membrane protein structure determination” and Dan’s poster was entitled “NMR solution structure of Opa60: a Neisserial membrane protein that mediates host phagocytosis”.

Dan and Linda contribute to CIL’s Biomolecular NMR Product Catalog.

The new Cambridge Isotope Laboratories, Inc. Biomolecular NMR Product Catalog has pieces written by various NMR spectroscopists that utilize their isotopes. Dan adn Linda wrote a piece entitled “The role of deuterated detergents in NMR structure determination of membrane proteins” and is found on page 33.

Linda, Dan, and Brett attended Frontiers of NMR in Biology Keystone Symposium

Dan presented a poster entitled “NMR Backbone Assignment of Opa I: A mediator of host-Neisseria interactions” and Brett presented a poster entitled “Investigations towards improving solution NMR paramagnetic relaxation enhancement distance restraints for MTSSL labeled α-helical membrane proteins”. Both were invited to orally present poster previews and Dan received a travel award. The meeting was located in Big Sky, Montana and the snow was fantastic.lone-mountain.JPG2010_0119aa.JPGiceclimbing.jpg

Brett and Dan present posters at 39th Southeastern Magnetic Resonance Conference

600.jpgBrett and Dan presented posters at the 39th Southeastern Magnetic Resonance Conference (SEMRC) which was held at the University of Florida campus on October 22-24, 2010. The focus of the conference is on the exchange of ideas related to NMR-, EPR-, and MRI-based research as well as on the development of these techniques and new applications. Dan presented a poster entitled “Preparation and NMR backbone assignment of OpaI: A mediator of host Neisseria interactions”. Brett presented “Motional model of nitroxide spin label side chain dynamics on an α-helical membrane protein” and received a travel grant.

Dan wins an award at the 2010 Huskey Research Exhibition

Dan Fox received a Student Voted Top Poster in Physical Science and Mathematics for the poster he presented at the 2010 Huskey Research Exhibition.
The University of Virginia Graduate School of Arts & Sciences held the 10th Annual Robert J. Huskey Research Exhibition on April 5, 2010.
