Sml1 protein

Patent Granted Trefoil factor 2 is a protein that in humans is encoded by the TFF2 gene.[1][2][3] 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. Their functions are not defined, but they may protect the mucosa from insults, stabilize the mucus layer and affect healing of the epithelium.
