Donald S. Sabatini was a renowned American cell biologist who made significant contributions to the field of cellular biology, particularly in the areas of protein synthesis and cellular architecture. Born on June 12, 1931, in Chicago, Illinois, Sabatini's interest in biology and science began at an early age, which would eventually lead him to pursue a career in cell biology. He attended the University of Chicago, where he earned his Bachelor's degree in 1952 and his Ph.D. in 1956, under the guidance of prominent biochemist, Jesse W. Beams.
Early Career and Research
Sabatini’s early career was marked by his postdoctoral research at the Rockefeller Institute for Medical Research (now known as Rockefeller University) in New York City, where he worked alongside prominent scientists, including George E. Palade and Philip Siekevitz. During this period, Sabatini became fascinated with the concept of cellular architecture and the mechanisms of protein synthesis. His research focused on understanding the structural and functional organization of cells, particularly the role of the endoplasmic reticulum (ER) in protein synthesis and transport.
Discovery of the Rough Endoplasmic Reticulum
Sabatini’s most notable contribution to the field of cell biology was his discovery of the rough endoplasmic reticulum (RER), a type of organelle found in eukaryotic cells. The RER is characterized by the presence of ribosomes attached to its surface, which are responsible for protein synthesis. Sabatini’s work on the RER led to a deeper understanding of the mechanisms of protein synthesis and the role of the ER in cellular processes. His research also shed light on the importance of the RER in various cellular functions, including protein folding, modification, and transport.

| 1958 | Discovery of the rough endoplasmic reticulum (RER) |
| 1963 | Elucidation of the role of RER in protein synthesis and transport |
| 1970 | Development of new methods for studying cellular architecture and organelle function |
Awards and Recognition
Sabatini’s contributions to the field of cell biology were recognized through numerous awards and honors. He was elected as a member of the National Academy of Sciences in 1973 and received the Louisa Gross Horwitz Prize in 1979 for his outstanding contributions to biology and biochemistry. Sabatini was also awarded the Albert Lasker Award for Basic Medical Research in 1983, in recognition of his pioneering work on the RER and its role in protein synthesis.
Legacy and Impact
Sabatini’s legacy extends beyond his scientific contributions, as he has inspired generations of cell biologists and researchers. His work has had a significant impact on our understanding of cellular processes and has led to the development of new therapeutic approaches for various diseases, including cancer and neurodegenerative disorders. Sabatini’s research has also paved the way for the development of new technologies, such as protein engineering and gene therapy.
