Predicted to enable KDEL sequence binding activity. Predicted to be involved in endoplasmic reticulum to Golgi vesicle-mediated transport; protein retention in ER lumen; and retrograde vesicle-mediated transport, Golgi to endoplasmic reticulum. Predicted to be located in Golgi membrane and endoplasmic reticulum membrane. Predicted to be active in cis-Golgi network and endoplasmic reticulum. Predicted to colocalize with COPI-coated vesicle membrane. Orthologous to human KDELR3 (KDEL endoplasmic reticulum protein retention receptor 3). [provided by Alliance of Genome Resources, Apr 2022]
