description Michael Rosbash Overview
Michael Rosbash is an American chronobiologist and geneticist at Brandeis University, where he has conducted research for decades. He shared the 2017 Nobel Prize in Physiology or Medicine with Jeffrey Hall and Michael Young for their discoveries of the molecular mechanisms governing biological clocks. Working with Drosophila, Rosbash and Hall identified the period gene's role in circadian oscillation and demonstrated that its protein product PER accumulates and degrades in a 24-hour cycle. This transcription-translation feedback loop proved conserved across many organisms, including mammals.
help Michael Rosbash FAQ
What specific biological process did Michael Rosbash win a Nobel Prize for uncovering?
Michael Rosbash won the Nobel Prize for discovering the molecular mechanisms that govern circadian rhythms. He identified how specific proteins build up and break down over a 24-hour cycle to regulate the biological clock.
At what institution is Michael Rosbash a faculty member?
Rosbash is an American chronobiologist and geneticist who has conducted research at Brandeis University for decades. His long-standing collaboration with Jeffrey Hall took place at this institution.
With whom did Michael Rosbash share the 2017 Nobel Prize?
He shared the 2017 Nobel Prize in Physiology or Medicine with his Brandeis colleague Jeffrey Hall and Rockefeller University researcher Michael Young. Together, they solved the mystery of how living things keep time.
How did Michael Rosbash and Jeffrey Hall isolate the mechanisms of the biological clock?
The researchers isolated the period gene in fruit flies (Drosophila melanogaster) in the 1980s. They found that the mRNA and protein produced by this gene fluctuated in a 24-hour cycle, demonstrating the core mechanics of sleep regulation.
