Background: TFF2

The trefoil factor (TFF) family contains three secreted, protease-resistant polypeptides that help to maintain gastrointestinal system integrity. Family members are 7-12 kDa in size, and contain a 3-disulfide bond generated trefoil structure that resembles a meadow clover. TFF1, 2 and 3 are produced in different areas of the digestive tract, and promote restitution, or the resealing of superficial wounds after injury.

SML1, SP, Spasmolysin, Spasmolytic Polypeptide

Entrez Gene IDs

7032 (Human); 21785 (Mouse); 116592 (Rat)
