Chromogranin A is cleaved by an endogenous prohormone convertase to produce several peptide fragments. See chromogranin A GeneRIFs for references. In immunohistochemistry it can be used to identify a range of neuroendocrine tumours and is highly specific for both benign and malignant cells of this type.[13]
Mass spec data shows that several peptides originating from CHGA (163-194; 194–214; 272–295 are significantly lower in samples from ulcerative colitis patients compared to control biopsies.[14]
