Research Backgrounds

Function:

Receptor for the C-terminal sequence motif K-D-E-L that is present on endoplasmic reticulum resident proteins and that mediates their recycling from the Golgi back to the endoplasmic reticulum. Binding is pH dependent, and is optimal at pH 5-5.4 (By similarity).

Subcellular Location:

Endoplasmic reticulum membrane>Multi-pass membrane protein. Golgi apparatus membrane>Multi-pass membrane protein. Cytoplasmic vesicle>COPI-coated vesicle membrane>Multi-pass membrane protein.
Note: Localized in the Golgi in the absence of bound proteins with the sequence motif K-D-E-L. Trafficks back to the endoplasmic reticulum together with cargo proteins containing the sequence motif K-D-E-L.

Extracellular region or secreted Cytosol Plasma membrane Cytoskeleton Lysosome Endosome Peroxisome ER Golgi apparatus Nucleus Mitochondrion Manual annotation Automatic computational assertionSubcellular location
Family&Domains:

Binds the C-terminal sequence motif K-D-E-L in a hydrophilic cavity between the transmembrane domains. This triggers a conformation change that exposes a Lys-rich patch on the cytosolic surface of the protein (By similarity). This patch mediates recycling from the Golgi to the endoplasmic reticulum, probably via COPI vesicles (By similarity).

Belongs to the ERD2 family.
