Background: TFF3

Trefoil Factor 3 (TFF3) is one of three trefoil peptides secreted by epithelial cells that line mucus membranes. Trefoils contribute to protection and repair of the gastrointestinal tract. TFF3 is secreted by mucus-producing goblet cells in the large and small intestines and lower respiratory tract. It is mainly active as a disulfide-linked homodimer. The mature 59 amino acid (aa), 6.5 kDa human TFF3 contains one trefoil structure formed by intramolecular disulfides and shows 76% aa identity with mouse TFF3.
