title: Proinsulin trafckin and processing in the pancreatic B cell.
abstract: Insulin is synthesized as a precursor, preproinsulin, in the rough endoplasmic reticulum of the pancreatic B cell. The combination of precursor processing and the movement of products in vesicles from one subcellular compartment to the next results in insulin becoming stored in secretory granules ready for release in response to a secretagogue.
