REG4 Information: REG4 Protein, REG4 Antibody and REG4 Gene

REG4 Gene family

REG4 Protein

REG4 protein function

Calcium-independent lectin displaying mannose-binding specificity and able to maintain carbohydrate recognition activity in an acidic environment. May be involved in inflammatory and metaplastic responses of the gastrointestinal epithelium. {ECO:0000269|PubMed:12819006, ECO:0000269|PubMed:20692269}.

REG4 protein expression

Tissue specificity

Highly expressed in the gastrointestinal tract including the duodenum, jejunum, ileum, ileocecum, appendix, descending colon, pancreas and small intestine. Weakly expressed in normal colon and stomach. Strongly expressed in most colorectal tumors than in normal colon. Preferentially expressed in mucinous tumors and in some cases neuro-endocrine tumors. Expressed in mucus-secreting cells and enterocyte-like cells. In small intestine expressed at the basal perinuclear zone of goblet cells.


Up-regulated by mucosal injury from active Crohn's disease or ulcerative colitis. Up-regulated in colorectal tumors. Up-regulated in epithelial cells at regenerating margins of peptic ulcers in the stomach and duodenum.
