Chromogranin A is a secretory protein. It is located in a large, dense-core vesicle of neuroendocrine cells. Chromogranin A-derived peptides are involved in a range of activities like glucose metabolism, tumor angiogenesis, regulation of blood pressure, and neuroprotection. The neuroendocrine cells have nerve and hormone aspects and are found in all organs of the body. These cells can give rise to both benign and malignant tumors.
