Cell biologist whose work with James D. Jamieson traced transport of secretory proteins through pancreatic cells. Following newly synthesized material connected distinct cellular compartments into a functional secretory pathway.[ref]
Günter Blobel Created 2026-10-18 Updated 2026-11-05
Cell biologist studying protein targeting across membranes. With Bernhard Dobberstein, Blobel reconstructed aspects of cotranslational protein translocation, connecting information in a growing polypeptide with delivery to the secretory pathway.[ref]
