Protein Structure
UniProt Annotation
Function May play a role in local mechanisms of mucosal immunity and seems to have a proinflammatory function. May play a role in inflammatory bowel disease. Activates STAT1 and STAT3, MAPK1/3 (ERK1/2), JUN and AKT. Induces expression of SOCS3, TNF-alpha and IL-8, secretion of IL-8 and IL-10 and surface expression of ICAM1. Decreases proliferation of intestinal epithelial cells. Is inhibited by heparin. {ECO:0000269PubMed:14764663, ECO:0000269PubMed:15178681, ECO:0000269PubMed:18483078}.
Subcellular Localization Secreted {ECO:0000269PubMed:18483078}.
Disease Associations
Tissue Specificity Expressed in HVS transformed T-cells but not other T-cell lines or primary stimulated T-cells. Expressed in colonic T-cells including Th17 inflammatory T-cells; the expression is significantly increased in serum of patients with Crohn's disease (at protein level). {ECO:0000269PubMed:18483078}.
