Predicted to enable lactate transmembrane transporter activity and pyruvate transmembrane transporter activity. Involved in plasma membrane lactate transport. Located in cytoplasm and plasma membrane. Is active in several cellular components, including Schaffer collateral - CA1 synapse; hippocampal mossy fiber to CA3 synapse; and parallel fiber to Purkinje cell synapse. Is integral component of postsynaptic density membrane. Orthologous to human SLC16A7 (solute carrier family 16 member 7). [provided by Alliance of Genome Resources, Apr 2022]
