MSH: A type of chromogranin which was initially characterized in a rat PHEOCHROMOCYTOMA CELL LINE. It is found in many species including human, rat, mouse, and others. It is an acidic protein with 626 to 657 amino acid residues. In some species, it inhibits secretion of PARATHYROID HORMONE or INSULIN and exerts bacteriolytic effects in others.,NCI: Chromogranin B is a tyrosine-sulfated secretory protein found in a wide variety of peptidergic endocrine cells. Chromogranin functions as a neuroendocrine secretory granule protein which may be the precursor for other biologically active peptides. (LocusLink)
