Also known as chromofungin, catestatin, CgA, SP-I, parathyroid secretory protein 1, chromogranin-A, CHGA, betagranin (N-terminal fragment of chromogranin A)

Chromogranin-A (CgA) or parathyroid secretory protein 1 is encoded in the human by the 'gene CHGA'''''. Cga is a member of the granin family of neuroendocrine secretory proteins. As such, it is located in secretory vesicles of neurons and endocrine cells such as islet beta cell secretory granules in the pancreas.

Chromogranin-A (CgA) or parathyroid secretory protein 1 is encoded in the human by the 'gene CHGA. Cga is a member of the granin family of neuroendocrine secretory proteins. As such, it is located in secretory vesicles of neurons and endocrine cells such as islet beta cell secretory granules in the pancreas.

== Tissue distribution == Examples of cells producing chromogranin-A (CgA) are chromaffin cells of the adrenal medulla, paraganglia, enterochromaffin-like cells and beta cells of the pancreas. It is present in islet beta cell secretory granules. chromogranin-A (CgA)+ Pulmonary neuroendocrine cells account for 0.41% of all epithelial cells in the conducting airway, but are absent from the alveoli.
