Antigen: Chromogranin A

Background

NCI Identification Number:

10131

Antigen Name:

Chromogranin A

CPTC Name:

CPTC-CHGA

Aliases:

parathyroid secretory protein 1; CHGA; CGA; CgA; SP-I

Function:

The protein encoded by this gene is a member of the chromogranin/secretograninfamily of neuroendocrine secretory proteins. It is found in secretory vesicles of neurons and endocrine cells. This gene product is a precursor to three biologically active peptides; vasostatin, pancreastatin, and parastatin. These peptides act as autocrine or paracrine negative modulators of the neuroendocrine system. Other peptides, including chromostatin, beta-granin, WE-14 and GE-25, are also derived from the full-length protein. However, biological activities for these molecules have not been shown. Pancreastatin strongly inhibits glucose induced insulin release from the pancreas.
