Proteins can be secreted, or transferred out of a cell, by multiple pathways. Regulated secretion is one of these processes. In regulated secretion proteins are secreted from a cell in large amounts when a specific signal is detected by the cell. The example used in this animation is the release of insulin after a glucose signal enters a pancreatic beta cell.
