RC   TISSUE=Kidney;
RG   NIH - Xenopus Gene Collection (XGC) project;
RL   Submitted (OCT-2003) to the EMBL/GenBank/DDBJ databases.
CC   -!- FUNCTION: Receptor for the C-terminal sequence motif K-D-E-L that is
CC       present on endoplasmic reticulum resident proteins and that mediates
CC       their recycling from the Golgi back to the endoplasmic reticulum.
CC       {ECO:0000250|UniProtKB:P24390}.
CC   -!- SUBCELLULAR LOCATION: Golgi apparatus membrane
CC       {ECO:0000250|UniProtKB:P33946}; Multi-pass membrane protein
CC       {ECO:0000250|UniProtKB:P33946}. Cytoplasmic vesicle, COPI-coated
CC       vesicle membrane {ECO:0000250|UniProtKB:P33946}; Multi-pass membrane
CC       protein {ECO:0000250|UniProtKB:P33946}. Endoplasmic reticulum membrane
CC       {ECO:0000250|UniProtKB:P33946}; Multi-pass membrane protein
CC       {ECO:0000250|UniProtKB:P33946}. Endoplasmic reticulum-Golgi
CC       intermediate compartment membrane {ECO:0000250|UniProtKB:P33946};
CC       Multi-pass membrane protein {ECO:0000250|UniProtKB:P33946}.
CC       Note=Localized in the Golgi in the absence of bound proteins with the
CC       sequence motif K-D-E-L. Trafficks back to the endoplasmic reticulum
CC       together with cargo proteins containing the sequence motif K-D-E-L.
CC       {ECO:0000250|UniProtKB:P33946}.
CC   -!- SIMILARITY: Belongs to the ERD2 family. {ECO:0000305}.
