| Identity |
| Other names | pS2 |
| HGNC (Hugo) | TFF1 |
| Location | 21q22.3 |
| Location_base_pair | Starts at 42655460 and ends at 42659713 bp from pter ( according to hg18-Mar_2006) [Mapping] |
| Local_order | belongs to the TFF cluster |
| 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 |
| 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 |
