KDELR1 - KDEL endoplasmic reticulum protein retention receptor 1 Gene
Also Known as ERD2; HDEL; PM23; ERD2.1
Species: Homo sapiens
About KDELR1
This gene has 5 transcripts (splice variants), 119 orthologues and 2 paralogues. Ubiquitous expression in ovary (RPKM 78.6), thyroid (RPKM 73.5) and 25 other tissues.
Summary
Retention of resident soluble proteins in the lumen of the endoplasmic reticulum (ER) is achieved in both yeast and animal cells by their continual retrieval from the cis-Golgi, or a pre-Golgi compartment. Sorting of these proteins is dependent on a C-terminal tetrapeptide signal, usually lys-asp-glu-leu (KDEL) in animal cells, and his-asp-glu-leu (HDEL) in S. cerevisiae. This process is mediated by a receptor that recognizes, and binds the tetrapeptide-containing protein, and returns it to the ER. In yeast, the sorting receptor encoded by a single gene, ERD2, which is a seven-transmembrane protein. Unlike yeast, several human homologs of the ERD2 gene, constituting the KDEL receptor gene family, have been described. The protein encoded by this gene was the first member of the family to be identified, and it encodes a protein structurally and functionally similar to the yeast ERD2 gene product.
