Monocarboxylate transporter 4

Monocarboxylate transporter 4 (MCT4) also known as solute carrier family 16 member 3 is a protein that in humans is encoded by the SLC16A3 gene. Northern and western blotting and EST database analyses showed MCT4 to be widely expressed and especially so in glycolytic tissues such as white skeletal muscle fibers, astrocytes, white blood cells, chondrocytes, and some mammalian cell lines.
