Chromogranin-A Isoform 1 Preproprotein or CHGA is part of the neuroendocrine secretory proteins of the chromogranin/secretogranin family. CHGA is a precursor of numerus enzymes such as pancreastatin, catestatin, vasostatin-1,vasostatin-2, and parastatin. The protein acts as a negative regulator the neuroendocrine activity of autocrine or nearby cells (paracrine). CHGA causes further production of secretory granules that contains insulin in pancreatic islet beta cells.
CHGA produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain (19-457 a.a.) and fused to a 6 aa His Tag at C-terminus containing a total of 448 amino acids and having a molecular mass of 50kDa.CHGA shows multiple bands between 50-70kDa on SDS-PAGE, reducing conditions and purified by proprietary chromatographic techniques.
| UniProt Protein Function: | CHGA: a member of the chromogranin/secretogranin family of neuroendocrine secretory proteins. It is found in secretory vesicles of neurons and endocrine cells and is a precursor to multiple biologically active peptides including vasostatin, pancreastatin, and chromostatin. Binds calcium with a low-affinity. Vasostatin negatively regulates angiogenesis and has antibacterial activity against some Gram-positive bacteria. Pancreastatin inhibits glucose induced insulin release from the pancreas. Chromostatin inhibits catecholamine release from chromaffin cells. |
| UniProt Protein Details: | Protein type:Secreted, signal peptide; Secreted; Vesicle; Cell adhesion Chromosomal Location of Human Ortholog: 14q32 Cellular Component: extracellular space; perinuclear region of cytoplasm; secretory granule Biological Process: defense response to Gram-negative bacterium; defense response to Gram-positive bacterium; mast cell activation; mast cell chemotaxis; mast cell cytokine production; mast cell degranulation; negative regulation of catecholamine secretion; negative regulation of vasodilation; organelle organization and biogenesis; positive regulation of cAMP metabolic process; regulation of blood pressure; regulation of the force of heart contraction |
| NCBI Summary: | The protein encoded by this gene is a member of the chromogranin/secretogranin family 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. Two other peptides, catestatin and chromofungin, have antimicrobial activity and antifungal activity, respectively. Two transcript variants encoding different isoforms have been found for this gene.
