UniProtKB - P11168 (GTR2_HUMAN)

Protein

Solute carrier family 2, facilitated glucose transporter member 2

Gene

SLC2A2

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

Functioni

Facilitative glucose transporter. This isoform likely mediates the bidirectional transfer of glucose across the plasma membrane of hepatocytes and is responsible for uptake of glucose by the beta cells; may comprise part of the glucose-sensing mechanism of the beta cell. May also participate with the Na+/glucose cotransporter in the transcellular transport of glucose in the small intestine and kidney.
