PHYSICAL PROPERTIES
STRUCTURE
motifs/domains
  • three intrachain disulfide bonds, forming the three leaf structure (P domain, trefoil motif)
  • at least one copy of the trefoil motif, a 40-amino acid domain that contains three conserved disulfides
  • HOMOLOGY
    Homologene
    FAMILY
  • trefoil family
  • CATEGORY regulatory , secretory
    SUBCELLULAR LOCALIZATION extracellular
    basic FUNCTION
  • maybe involved in mitogenic processes
  • cell adhesion migration by controling the expression of APC and E-cadherin-catenin complexes
  • may have a role in promoting cell migration
  • regulating mucosal regeneration and repair
  • may enhance mucosal healing by modulating motogenic activity, inhibiting apoptosis, and promoting angiogenesis
  • likely to contribute to oral wound healing
  • could play a role in neurosensory signaling
  • contributes to the malignant behavior of colon cancer cells
  • playing a pivotal role in corneal wound healing mechanism
  • may have a role in normal thyroid tissue function
  • plays a major part in regeneration and restitution processes in urinary tract epithelia
  • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling
    TFF3-mediated pathway for stimulation of beta-cell replication that could ultimately be exploited for expansion or preservation of islet beta-cell mass
    a component
    INTERACTION
    DNA
    RNA
    small molecule
    protein
  • TWIST1 is an important potential downstream effector, playing a key role in TFF3-modulated metastasis in gastric cancer

    overexpression in hepatocellular carcinogenesis, and the specific promoter CpG hypomethylation may be one of the regulation mechanisms of TFF3 overexpression
    tumoral     --over  
    by hypomethylation of the promoter/enhancer region, significantly lower in prostate carcinoma compared to benign prostatic hyperplasia

    Variant & Polymorphism
    Candidate gene
    Marker
  • overexpression and promoter hypomethylation of trefoil factors may serve as biomarkers in prostate carcinoma
  • novel serum marker for early detection and/or monitoring of poorly differentiated endometrioid endometrial carcinomas (G3-EEC) patients
  • TFF2 and probably also TFF3 are candidate biomarkers for nephrolithiasis and possibly other inflammatory conditions of the urinary tract
  • Therapy target
  • having broad implications for developing novel therapeutic strategies for treating nonhealing wounds
  • SystemTypeDisorderPubmed
    immunologyautoimmunedigestive
    may have therapeutic potential in the treatment of inflammatory bowel disease, and one of the mechanisms may related to inhibit the TLR4/NF-kappaB signaling pathways
    ANIMAL & CELL MODELS
  • Tff3-deficient (Tff3(-)(/)(-)) mice (Paulsen, 2008)
  • Tff3 knock-out animals show an accelerated presbyacusis and a hearing loss of about 15 dB at low frequencies increasing to 25 dB loss at higher frequencies
