ERp72 Proteins and Enzymes

ERp72 is an endoplasmic reticulum luminal protein that is both a stress protein and a member of the protein disulfide isomerase family of proteins. Sequence analysis of ERp72 shows that it shares sequence identity with PDI (protein disulphide isomerase) at three discrete regions, as well as containing the ER retention signal KEEL at its C-terminus. ERp72 is shown to have three copies of sequence believed to be CGHC-containing active sites, which are also found in PDI. These CGHC sites are ...
