Gene Information

human ... TFF1(7031)

General description

Members of the trefoil family are characterized by having at least one copy of the trefoil motif, a 40-amino acid domain that contains three conserved disulfides. They are stable secretory proteins expressed in gastrointestinal mucosa.
Trefoil factor 1 (TFF1) also known as breast cancer estrogen-inducible protein (BCEI) and pS2 protein, is highly expressed in the gastrointestinal mucosa. The protein was first characterized in the breast cancer cell line MCF-7. The gene TFF1 is localized on human chromosome 21q22.3.

Immunogen

Synthetic peptide directed towards the middle region of human TFF1

Biochem/physiol Actions

The major functions of TFF1 are mucosal repair incase of damage and maintenance of mucosal integrity. TFF1 promotes cell migration in breast cancer cells in response to estrogen. TFF1 is a tumour suppressor gene in gastric cancer and the mutation of which leads to development and progression of gastric cancer. TFF1 is an important marker in lobular endocervical glandular hyperplasia. TFF1 is a potent inhibitor of growth of calcium oxalate crystal growth in renal tubules.

Sequence

Synthetic peptide located within the following region: PRERQNCGFPGVTPSQCANKGCCFDDTVRGVPWCFYPNTIDVPPEEECEF

Physical form

Purified antibody supplied in 1x PBS buffer with 0.09% (w/v) sodium azide and 2% sucrose.
