Sep15 and SelM are eukaryotic selenoproteins that have a thioredoxin-like domain and a surface accessible active site redox motif [1]. This suggests that they function as thiol-disulphide isomerases involved in disulphide bond formation in the endoplasmic reticulum [1]. Structurally it resembles the thioredoxin-fold.	Domain
