متن کاملGetting Secretory Granules Ready for Prime Time
Several rare human diseases have shed important light on the secretory pathway required for lymphocyte cytotoxicity. In this issue of Cell, Feldmann et al. identify mutations in Munc13-4 as a cause of familial hemophagocytic lymphohistiocytosis. Munc13-4 appears to be involved in the priming of cytotoxic granules prior to fusion with the plasma membrane.
متن کاملParotid secretory granules: crossroads of secretory pathways and protein storage.
Saliva plays an important role in digestion, host defense, and lubrication. The parotid gland contributes a variety of secretory proteins-including amylase, proline-rich proteins, and parotid secretory protein (PSP)-to these functions. The regulated secretion of salivary proteins ensures the availability of the correct mix of salivary proteins when needed. In addition, the major salivary glands...
متن کاملZymophagy: Selective Autophagy of Secretory Granules
Timing is everything. That's especially true when it comes to the activation of enzymes created by the pancreas to break down food. Pancreatic enzymes are packed in secretory granules as precursor molecules called zymogens. In physiological conditions, those zymogens are activated only when they reach the gut, where they get to work releasing and distributing nutrients that we need to survive. ...
متن کاملProteomics Analysis of Insulin Secretory Granules*□S
Insulin secretory granules (ISGs) are cytoplasmic organelles of pancreatic -cells. They are responsible for the storage and secretion of insulin. To date, only about 30 different proteins have been clearly described to be associated with these organelles. However, data from two-dimensional gel electrophoresis analyses suggested that almost 150 different polypeptides might be present within ISGs...
