Predicted to enable amino acid transmembrane transporter activity and thyroid hormone transmembrane transporter activity. Acts upstream of or within with a negative effect on thyroid hormone generation and thyroid-stimulating hormone secretion. Acts upstream of or within thyroid hormone transport. Located in apical plasma membrane. Is expressed in several structures, including alimentary system; cardiovascular system; central nervous system; cochlea; and limb. Used to study Allan-Herndon-Dudley syndrome. Human ortholog(s) of this gene implicated in Allan-Herndon-Dudley syndrome and intellectual disability. Orthologous to human SLC16A2 (solute carrier family 16 member 2). [provided by Alliance of Genome Resources, Apr 2022]
