Trefoil factor 1

pS2, Presenilin-2, TFF1
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. This gene, 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. [provided by RefSeq, Jul 2008] (from NCBI)

Synergistic deleterious effect of chronic stress and sodium azide in the mice hippocampus.
New
de Pablos et al., In Chem Res Toxicol, 06 Mar 2015
We found that chronic stress increases the levels of several proteins involved in Alzheimer´s disease pathogenesis, such as presenilin 1, presenilin 2 and S100beta, besides inducing the aggregation of Tau, ubiquitin and beta-amyloid proteins in the hippocampus.
