Roess to Visit Chemistry Department, Discuss Plasma Membrane Receptors

Posted on 1/18/2010 12:37:56 PM

The Department of Chemistry is pleased to announce that it will host Dr. Deborah Roess of the Department of Biomedical Sciences at Colorado State University on Friday, January 22, 2010.

Dr. Roess will visit the faculty and students of the department before giving the seminar “Single Molecule and Fluorescence Methods to Study Reorganization of Plasma Membrane Receptors During Signal Transduction.”

Dr. Roess's research uses laser-optical instrumentation to measure the lateral and rotational motions of plasma membrane components. One area of study is the molecular motions of luteinizing hormone (LH) receptors on luteal and Leydig cells. Movement of molecules, such as the LH receptor, in a membrane is affected by receptor and hormone structure, cytoskeletal components capable of physically anchoring the LH receptor in the membrane, and by interactions of the receptor with other membrane proteins. She is interested in determining how these features are involved in regulating functions of reproductive organs.

The chemistry seminar will be held from 3:35 to 4:25 p.m. in Weyandt 240. Light refreshments will be served, and all are welcome attend.
