InnateDB Annotation
Summary
CHGA undergoes proteolytic cleavage to give rise to biologically active peptides, including catestatin. Catestatin is a neuroendocrine peptide with effects on human autonomic function and has recently been found to be a cutaneous antimicrobial peptide by inducing mast cell activation. In mast cells, catestatin plays a role in the migration, degranulation and release of leukotriene and prostaglandins; in addition, catestatin also induces production of pro-inflammatory cytokines to prime the innate immune response.

Entrez Gene
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. 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.

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.
