Protein

Sodium/glucose cotransporter 2

Gene

SLC5A2

Organism
Homo sapiens (Human)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

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.
