KDEL (Lys-Asp-Glu-Leu) endoplasmic reticulum protein retention receptor 1; Required for the retention of luminal endoplasmic reticulum resident proteins via vesicular recycling. This receptor recognizes the C-terminal K-D-E-L motif. COPI-coated transport intermediates, either in the form of round vesicles or as tubular processes, mediate retrograde traffic of the KDEL receptor-ligand complexes. Also required for normal vesicular traffic through the Golgi.
Synonyms: KDELR1, KDELR1p, hKDELR1, KDELR1-001, KDELR1-002 ...
