Gluten immunochemistry motif", which is found in wheat and other "Triticeae" genera.(see also: ). Alpha-2 secalin, the glutinous protein in rye, is composed of two amino-terminal overlapping T-cell sites at positions (8-19) and (13-23). Although T-cell responses to many prolamins can be found in coeliac disease, one particular gliadin, α2-gliadin appears to be the focus of T-cells. These responses were dependent on prior treatment with tissue transglutaminase. Α2-gliadin differs from the other α-gliadins, specifically because it contains an insert of 14 amino acids. This particular insertion creates 6 T-cell sites where, in the most similar gliadins, there are 2 or less sites.
Wheat gluten (food) markets, health food stores and cooperatives.
