Secondary Accession Numbers Not Available
Name Endoplasmic reticulum resident protein 44
Description Not Available
Synonyms
  1. ER protein 44
  2. ERp44
  3. Thioredoxin domain-containing protein 4
Gene Name ERP44
Protein Type Enzyme
Biological Properties
General Function Involved in cell redox homeostasis
Specific 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
