Trefoil factor 1 is a protein that is encoded by the TFF1 gene.
Members of the trefoil family are characterized by having at least one copy of the trefoil motif, a 40aa 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.
Trefoil factor 1, which is expressed in the gastric mucosa, has also been studied because of its expression in human tumors.
This gene and two other related trefoil family member genes are found in a cluster on chromosome 21.
