monocarboxylate transporter 4; MCT 4; solute carrier family 16 member 3 (SLC16A3, MCT4)

Function

• proton-linked monocarboxylate transporter
• catalyzes rapid transport across the plasma membrane of many monocarboxylates including:
  • lactate
  • pyruvate
  • branched-chain oxo acids derived from leucine, valine & isoleucine
  • ketone bodies
    • acetoacetate
    • beta-hydroxybutyrate
    • acetate

Structure

• belongs to the major facilitator superfamily monocarboxylate porter (TC 2.A.1.13) family

Compartment

cell membrane

Expression

highly expressed in skeletal muscle
