DNA/RNA

Description

5kb gene; 3 exons

Transcription

600bp cDNA; coding sequence: 252 bp

Proteins

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
