Clinical Significance:

(No Suggestions) is an integral membrane glycoprotein that binds calcium in presynaptic vesicles of neurons and neuroendocrine cells. (No Suggestions) may be involved in synaptic vesicle formation and exocytosis. (No Suggestions) is reported to be expressed in a wide spectrum of neuroendocrine tumors including neuroblastomas, ganglioneuroblastomas, phaeochromocytomas, chromaffin and non-chromaffin paragangliomas. (No Suggestions) is also reported to be expressed in neuroendocrine tumors of epithelial type including pituitary adenomas, islet cell tumors, medullary carcinomas of thyroid, parathyroid adenomas, carcinoids of the bronchopulmonary and gastrointestinal tracts, neuroendocrine carcinomas of the bronchopulmonary and gastrointestinal tract and neuronendocrine carcinomas of the skin.
