Facts about Tumor suppressor candidate 3.
Specifically necessary for the glycosylation of a subset of acceptor sites that are close cysteine residues; in this event appears to act redundantly with MAGT1. In its oxidized form suggested to form transient mixed disulfides with a glycoprotein substrate to ease access to STT3B to the unmodified acceptor site.
