UniProtKB - P31639 (SC5A2_HUMAN)
Sodium/glucose cotransporter 2
SLC5A2
Functioni
Sodium-dependent glucose transporter. Has a Na+ to glucose coupling ratio of 1:1.
Efficient substrate transport in mammalian kidney is provided by the concerted action of a low affinity high capacity and a high affinity low capacity Na+/glucose cotransporter arranged in series along kidney proximal tubules.
