Protein Structure
UniProt Annotation
Function Mediates thiol-dependent retention in the early secretory pathway, forming mixed disulfides with substrate proteins through its conserved CRFS motif. Inhibits the calcium channel activity of ITPR1. May have a role in the control of oxidative protein folding in the endoplasmic reticulum. Required to retain ERO1L and ERO1LB in the endoplasmic reticulum (By similarity). {ECO:0000250}.
Subcellular Localization Endoplasmic reticulum lumen {ECO:0000255PROSITE-ProRule:PRU10138, ECO:0000269PubMed:15652484}.
Disease Associations
Tissue Specificity Widely expressed. {ECO:0000269PubMed:15652484}.
