RP NUCLEOTIDE SEQUENCE [LARGE SCALE MRNA].
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}.
