ITF can improve cytomorphosis ability for promoting cell migration with limited effect on cell proliferation, which can be enhanced with addition of mucin. The main mechanism of ITF in maintaining intestinal mucosal barrier may be attributed to acceleration of cell migration.

These results suggest that TFF3 may promote adhesion and spreading of cells to accelerate beta-cell maturation. This study indicates a functional role for TFF3 in pancreatic beta-cell maturation in the perinatal period, which is altered by low protein diet during gestation.
Title: Trefoil factor 3 in perinatal pancreas is increased by gestational low protein diet and associated with accelerated β-cell maturation.
The expression in activated microglial cells, which is demonstrated here for the first time, points towards a possible function for Tff3 in immune reactions in the CNS
Title: Tff3 is expressed in neurons and microglial cells.
Substantial amounts of TFF1 were detected only in the cytoplasm of epithelial cells in the submandibular glands granular convoluted tubules (GCT), while TFF2 and TFF3 were widely distributed in the cytoplasm of epithelial cells of intercalated ducts

Goblet cell-secreted TFF3, IgGFcgammaBP and Muc2, existing in the two intestinal mucus layers, are bound together by covalent interactions in the soluble fraction of intestinal mucus and form heteropolymers.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
