Proteins of the TFF family are characterized by obtaining a minimum of 1 copy of the trefoil motif, a 40-amino acid domain that contains 3 conserved disulfides. Trefoil Factors are stable secretory proteins expressed in gastrointestinal mucosa which protect the mucosa from insults, stabilize the mucus layer and affect healing of the epithelium.TFF2 inhibits gastric acid motility & secretion. TFF2 stabilizes glycoproteins in the mucus gel through interactions with carbohydrate side chains. TFF3 induces ciliogenesis and promotes airway epithelial ciliated cell differentiation, relatively through an epidermal growth factor receptor-dependent pathway. TFF3 overexpression is crucial for progression in mouse and human hepatocellular carcinogenesis. TFF-3 is normally expressed in hepatocellular carcinoma and its expression associates with tumor grade.
The Trefoil Factor-3 Rat was constructed as a recombinant protein with a 9 a.a C-terminal fusion of Flag-Tag (1 aa N-terminal+8 aa C-terminal). The TFF3 Rat produced in E.coli, is 7.7kDa protein containing a total of 68 amino acid residues.
UniProt Protein Function: | Function: Involved in the maintenance and repair of the intestinal mucosa. Promotes the mobility of epithelial cells in healing processes (motogen) |
UniProt Protein Details: | By similarity. Subunit structure: Monomer By similarity. Homodimer; disulfide-linked By similarity. Subcellular location: Secreted � extracellular space � extracellular matrix � apical lamina Ref.1 Ref.7. Tissue specificity: Expressed in goblet cells of the intestines, and colon, in paraventricular hypothalamus and supraoptic nuclei. Weakly expressed in gastric epithelial cells (at protein level). Expressed by goblet cells of small and large intestinal epithelia, kidney and stomach. Expressed in the paraventricular hypothalamus, arcuate nucleus and amygdala of the brain. Weakly expressed in gastric epithelial cells. Ref.1 Ref.3 Ref.5 Ref.8 Ref.9 Induction: Up-regulated by hypoxia in gastric epithelial cells. Up-regulated by hypoxia-inducible factor 1 alpha (HIF1A). Ref.9 Sequence similarities: Contains 1 P-type (trefoil) domain. |
