Nobel Prize for Synbio Advisor

Member of the external Scientific Advisory Board of Center for Synthetic Biology Professor Brian K. Kobilka of Stanford University has been honoured with the 2012 Nobel Prize in chemistry for describing our cells' sensory gatekeepers. 

Professor Kobilka receives the award alongside Professor Robert J. Lefkowitz of Duke University for the discovery of the G-Protein Coupled Receptors (GPCRs). Since their discovery, researchers have found these proteins on the cell surfaces of virtually all types of eukaryotic cells, including nearly a thousand variants in cells of the human body. The great diversity among the GPCRs in the human body allow different types of cells to react differently to the same external stimuli, e.g. a specific hormone or neurotransmitter. 

Several of the neurobiologists that participate in the Center for Synthetic Biology have collaborated with Professor Kobilka. Member of the Center's steering group, Professor Ulrik Gether has a tight collaboration with the Nobel Laureate with whom he has published numerous joint papers since 1995 (see a joint list of publications below). Claus J. Løland from the same research laboratory has also published jointly with Professor Kobilka.

When the UNIK grant was awarded to establish Center for Synthetic Biology, three Associate Professor positions were advertised internationally and filled by young promising researchers. Within the neurobiology area headed by Professor Gether, the position was assigned to Søren G.F. Rasmussen. Because of his ongoing successful work in Brian Kobilka's lab on the crystal structures and conformational changes of adrenergic receptors, the leadership of the UNIK Center for Synthetic Biology fully accepted and supported that Søren stayed in Brian Kobilka's lab for an additional two years to complete his magnificent work. Søren G.F. Rasmussen's research efforts at Stanford resulted in several seminal papers including six joint Nature papers (three with him as first author, one with shared first authorship), one Nature review and two Nature Methods papers as well as two papers published in Science.
