Recombinant Human Endoplasmic reticulum resident protein 44 (ERP44)

Uniprot Id

Q9BS26

Target Species

Human

Target Name

ERP44

Target Full Name

Endoplasmic reticulum resident protein 44

Target 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 ERO1A and ERO1B in the endoplasmic reticulum.

Target Subcellular Location

Endoplasmic reticulum lumen.

Target Background

This gene encodes a member of the protein disulfide isomerase (PDI) family of endoplasmic reticulum (ER) proteins. It has an inferred N-terminal signal peptide, a catalytically active thioredoxin (TRX) domain, two TRX-like domains and a C-terminal ER-retention sequence. This protein functions as a pH-regulated chaperone of the secretory pathway and likely plays a role in protein quality control at the endoplasmic reticulum - Golgi interface.
