Predicted to enable biotin transmembrane transporter activity; pantothenate transmembrane transporter activity; and sodium-dependent multivitamin transmembrane transporter activity. Predicted to be involved in anion transmembrane transport; sodium ion transport; and transport across blood-brain barrier. Predicted to act upstream of or within ion transport. Predicted to be located in brush border membrane and vesicle membrane. Is expressed in several structures, including 4-cell stage embryo; choroid plexus; pericardium; pituitary gland; and skeletal musculature. Orthologous to human SLC5A6 (solute carrier family 5 member 6). [provided by Alliance of Genome Resources, Apr 2022]
