Background: TFF2

Trefoil factor 2 (TFF2), also known as spasmolytic polypeptide (Sp) is a 20 kDa secreted trefoil factor family protein. It is a protease-resistant glycoprotein primarily produced by mucous-secreting cells of the stomach and duodenum and is upregulated in response to inflammation. TFF2 interacts with mucin and other TFF2-binding proteins to protect and repair mucosal epithelium. TFF2 is also expressed by macrophages and lymphocytes and may have a role in modulating immune system responses. The 106 residue mature human TFF2 contains two trefoil domains (aa 36-72 and aa 80-121) and one N-linked glycosylation site. Human TFF2 shares 71% and 87% aa sequence identity with canine and mouse TFF2, respectively.
