Enables identical protein binding activity; monocarboxylic acid transmembrane transporter activity; and organic cyclic compound binding activity. Involved in cellular response to organic cyclic compound and plasma membrane lactate transport. Located in apical plasma membrane and basolateral plasma membrane. Is integral component of plasma membrane. Human ortholog(s) of this gene implicated in familial hyperinsulinemic hypoglycemia 7. Orthologous to human SLC16A1 (solute carrier family 16 member 1).
