    Brian K. Kobilka (born in 1955) was awarded on 2012 the Nobel Prize in Chemistry together with Robert J. Lefkowitz for their research on G protein-coupled receptors. At present, Dr. Kobilka is the Hélène Irwin Fagan Chair in Cardiology and a Professor in the Department of Molecular and Cellular Physiology at Stanford University.

    Brian Kobilka started his studies at the University of Minnesota in Duluth, Minnesota, and then earned his medical degree from Yale University in New Haven, Connecticut. After a medical residency in St. Louis, Missouri, he moved to Duke University in Durham, North Carolina, where he started his Nobel Prize research. For the first time, Kobilka and his coworkers identified, purified and cloned a set of genes encoding mammalian adrenergic receptors, which were then realized to be similar to rhodopsin, the light-sensitive photoreceptor in the eye. A whole family of such receptors were found to exist: the G protein-coupled receptors (GPCRs) – which today are considered to be the largest family of transmembrane receptors in humans. Approximately one-third of all commercially available drugs use GPCRs as targets.

    After moving to Stanford University in California, Kobilka continued his work and managed to resolve and publish several high-resolution crystal structures of G protein-coupled receptors which, for the first time, revealed the molecular details of those receptors in action. Current efforts in Prof. Kobilka’s laboratory are focused on using a series of structural and biophysical tools to elucidate the dynamic structures of GPCRs and investigate the influence of pharmacological agents on GPCR signaling. In addition to his scientific achievements, Prof. Kobilka is a devoted advocate for physician-scientists. He has played an important role in integrating scientific research in the medical training curriculum at the Stanford University School of Medicine.
