Predicted to enable microtubule binding activity and olfactory receptor binding activity. Involved in regulation of intracellular transport. Located in endoplasmic reticulum membrane and endoplasmic reticulum tubular network. Is expressed in diaphragm; nervous system; neural retina; and skeletal musculature. Used to study hereditary spastic paraplegia 31. Human ortholog(s) of this gene implicated in distal hereditary motor neuronopathy type 5B and hereditary spastic paraplegia 31. Orthologous to human REEP1 (receptor accessory protein 1). [provided by Alliance of Genome Resources, Apr 2022]
