RP   NUCLEOTIDE SEQUENCE [LARGE SCALE MRNA].
RC   TISSUE=Kidney;
RG   The German cDNA consortium;
RL   Submitted (NOV-2004) to the EMBL/GenBank/DDBJ databases.
CC   -!- FUNCTION: Involved in the selective transport and maturation of TGF-
CC       alpha family proteins. {ECO:0000250}.
CC   -!- SUBUNIT: Interacts with AREG immature precursor and with immature TGFA,
CC       i.e. with a prosegment and lacking full N-glycosylation, but not with
CC       the fully N-glycosylated form. In the Golgi apparatus, may form a
CC       complex with GORASP55 and transmembrane TGFA (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane; Multi-pass
CC       membrane protein. Golgi apparatus membrane. Note=Located primarily in
CC       the ER; may cycle between the ER and the Golgi apparatus.
CC       {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the cornichon family. {ECO:0000305}.
