A physician and biochemist who discovered the structure and function of G-protein-coupled receptors, revolutionizing understanding of cellular communication and leading to numerous life-saving medications.
Robert Lefkowitz, a renowned American physician, internist, cardiologist, and biochemist, is best known for his groundbreaking discoveries that revealed the intricate workings of G protein-coupled receptors, earning him the 2012 Nobel Prize in Chemistry alongside Brian Kobilka. His pioneering work has revolutionized our understanding of cellular communication, paving the way for significant advancements in the fields of medicine and biochemistry.
Born on April 15, 1943, in The Bronx, New York, to Jewish parents Max and Rose Lefkowitz, Robert's family had emigrated to the United States from Poland in the late 19th century. He graduated from the Bronx High School of Science in 1959 and went on to attend Columbia College, where he earned a Bachelor of Arts in chemistry in 1962. Under the guidance of Ronald Breslow, Lefkowitz developed a strong foundation in chemistry that would later shape his research endeavors.
After graduating from Columbia University College of Physicians and Surgeons in 1966 with an M.D. degree, Lefkowitz served as a clinical and research associate at the National Institutes of Health from 1968 to 1970. He then joined Duke University Medical Center, where he was appointed associate professor of medicine and assistant professor of biochemistry in 1973. Over the years, he rose through the ranks, becoming a professor of medicine in 1977 and later, James B. Duke Professor of Medicine in 1982.
Lefkowitz's research focus on receptor biology and signal transduction led to several seminal discoveries. He is credited with:
