Mouse Monoclonal Antibody
Manufacturer: BD Biosciences 564563
Chromogranin A (CGA) is a member of the granin family of regulated secretory proteins that are found in secretory granules in endocrine and neuroendocrine cells and released in response to extracellular stimulation. Intracellularly, granins are important for targeting peptide hormones and neurotransmitters by their ability to aggregate in the low pH, high calcium environment of the trans-Golgi network. Extracellularly, peptides formed from proteolytic processing of granins regulate hormone secretion. CGA is a prohormone that can be cleaved into several biologically active peptides, such as pancreastatin, β-granin, vasostatin, catestatin, and parastatin. β- granin is an N-terminal fragment of CGA, while pancreastatin and catestatin are processed from the central region of CGA. Cells of the adrenal medulla, anterior pituitary, cerebral cortex as well as beta cells of the pancreas and a variety of tumor cell lines express CGA. The expression of CGA can be used to monitor the pancreatic differentiation of pluripotent stem cells.
