The Accident That Built the GPCR Field — Bob Lefkowitz

Lefkowitz was told in 1973 that hormone receptors were a figment of his imagination. The work that proved otherwise became the molecular foundation of GPCR pharmacology.

Nobel laureate Robert Lefkowitz traces the full arc of GPCR discovery — from developing the first radioligand for the beta-adrenergic receptor to purifying it, cloning it, and watching a sequencing run reveal structural homology with rhodopsin that nobody in the field had predicted. That 1986 paper established the GPCR superfamily. The same system yielded the GRK family and the beta-arrestins. This conversation is also about the human architecture behind that science: how a Vietnam War draft assignment in 1968 redirected a physician toward a question the field wasn't sure was real, what 18 months of unbroken failure at the NIH taught him about research, and why he argues that if 50% of your experiments succeed, you are not working on hard enough problems.

• How a Vietnam War draft sent a physician to the NIH — and gave rise to 50 years of GPCR receptor pharmacology
• Why Lefkowitz chose the beta-adrenergic system, and why he considers it the smartest scientific decision of his career
• The cloning race against Genentech: the "stupid idea" that worked and the intronless gene that ended the competition
• High output vs. low output failure — how to find the research territory between trivial problems and intractable ones
• What the Nobel call at 5 AM actually felt like: not jubilation, but relief — and a tear when he learned who he'd share it with
