Name Sodium-coupled monocarboxylate transporter 2
Description Not Available
Synonyms
  1. Electroneutral sodium monocarboxylate cotransporter
  2. Low-affinity sodium-lactate cotransporter
  3. Solute carrier family 5 member 12
Gene Name SLC5A12
Protein Type Transporter
Biological Properties
General Function Involved in transporter activity
Specific Function Acts as an electroneutral and low-affinity sodium (Na(+))-dependent sodium-coupled solute transporter. Catalyzes the transport across the plasma membrane of many monocarboxylates such as lactate, pyruvate, nicotinate, propionate, butyrate and beta-D- hydroxybutyrate. May be responsible for the first step of reabsorption of monocarboxylates from the lumen of the proximal tubule of the kidney and the small intestine. May play also a role in monocarboxylates transport in the retina. Mediates electroneutral uptake of lactate, with a stoichiometry of 2 Na(+) for each lactate
