| C2CD2 (21q22.3) / TFF1 (21q22.3) | TFF1 (21q22.3) / RABEP1 (17p13.2) | TFF1 (21q22.3) / RALB (2q14.2) | |
| DNA/RNA |
| Description | 5kb gene; 3 exons |
| Transcription | 600bp cDNA; coding sequence: 252 bp |
| Protein |
| Description | 84 amino acids, containing a peptide signal; the 60 AA-long mature secreted peptide contains one TFF (TreFoil Factor) domain and one acidic C-terminal domain |
| Expression | epithelial cells of the stomach surface |
| Localisation | cytoplasmic |
| Function | in the maintenance of mucosa integrity; unknown at the molecular level; deficient mice develop antro-pyloric adenoma |
| Homology | TFF2/SP (spasmolytic peptide) and TFF3/ITF (intestinal trefoil factor) |
| Implicated in |
| Note | |
| Disease | overexpressed in estradiol-dependent breast carcinomas; overexpressed in carcinoma of several other organs; loss of expression in half of gastric carcinomas (TFF1 is normally expressed in the stomach) |
| Prognosis | good prognosis factor, and marker of response to hormonal treatment in breast carcinomas |
