Synonyms MCT 4; MCT4; SLC16A3; Solute carrier family 16 member 3
DT Family Major Facilitator Superfamily (MFS)
Monocarboxylate Transporter (MCT) Family
Tissue Specificity Highly expressed in skeletal muscle.
Function This proton-linked monocarboxylate transporter catalyzes the rapid transport across the plasma membrane of many monocarboxylates such as lactate, pyruvate, branched-chain oxo acids derived from leucine, valine and isoleucine, and the ketone bodies acetoacetate, beta-hydroxybutyrate and acetate.
Endogenous Substrate(s) Monocarboxylates; Lactate; pyruvate; Branched-chain oxo acids
