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 act upstream of or within T cell apoptotic process and T cell differentiation. Located in cis-Golgi network and endoplasmic reticulum. Orthologous to human KDELR1 (KDEL endoplasmic reticulum protein retention receptor 1). [provided by Alliance of Genome Resources, Apr 2022]
