Biochemist/molecular biologist Joan Steitz was born #OTD in 1941. She (& team) figured out how our cells read/use genetic instructions to make proteins. A key person who helped crack the code on RNA—the molecule that acts like a messenger between DNA & and the proteins our bodies need. #WomenInSTEM

Color photograph of Joan Steitz (Joan Argetsinger Steitz), the distinguished American molecular biologist and biochemist renowned for her groundbreaking discoveries in RNA biology, including the identification of small nuclear ribonucleoproteins (snRNPs) essential to RNA splicing. She is pictured in a close-up portrait within a laboratory or research setting, smiling warmly and directly at the camera with an engaging, approachable expression that conveys enthusiasm and expertise. Steitz has gray hair pulled back, striking blue eyes, and is wearing large, elaborate dangling earrings adorned with purple gemstones and metallic accents. She is dressed in a rich purple blouse. The softly blurred background includes scientific elements such as lab benches, equipment, monitors, charts, and partial signage, evoking the environment of her long career at Yale University where she served as Sterling Professor of Molecular Biophysics and Biochemistry. #JoanSteitz #MolecularBiology #WomenInScience #Biochemistry #RNA

Colliding ribosomes are potent signals of cellular stress. But do cells use ‘programmed’ ribosome collisions to regulate gene expression? I’m excited to present a new story from my lab led by Frederick Rehfeld(@fred-rehfeld.bsky.social) which revealed that the answer is YES! Read on to find out how👇

Oxidative stress sensing by the translation elongation machinery promotes production of detoxifying selenoproteins

Selenocysteine, incorporated into polypeptides at recoded termination codons, plays an essential role in redox biology. Using GPX1 and GPX4, selenoenzymes that mitigate oxidative stress, as reporters,...
