Predicted to enable microtubule binding activity. Predicted to be involved in endoplasmic reticulum tubular network organization and mitotic nuclear membrane reassembly. Predicted to act upstream of or within cell division. Predicted to be located in endoplasmic reticulum and microtubule. Predicted to be integral component of membrane. Predicted to be active in cytoplasmic microtubule; endoplasmic reticulum membrane; and endoplasmic reticulum tubular network. Is expressed in heart valve; limb segment; trigeminal ganglion; and ventricular layer. Orthologous to human REEP3 (receptor accessory protein 3). [provided by Alliance of Genome Resources, Apr 2022]
