Funtion Uniprot: Facilitative glucose transporter, which is responsible for constitutive or basal glucose uptake (PubMed:18245775, PubMed:19449892, PubMed:25982116, PubMed:27078104, PubMed:10227690). Has a very broad substrate specificity; can transport a wide range of aldoses including both pentoses and hexoses (PubMed:18245775, PubMed:19449892). Most important energy carrier of the brain: present at the blood-brain barrier and assures the energy-independent, facilitative transport of glucose into the brain (PubMed:10227690). In association with BSG and NXNL1, promotes retinal cone survival by increasing glucose uptake into photoreceptors (By similarity).

Biological function from UniProt: #Sugar transport #Transport

Molecular function from UniProt:

Tissue specificity from UniProt: Detected in erythrocytes (at protein level). Expressed at variable levels in many human tissues.

Subcellular UniProt: #Cell membrane #Membrane

Alternative name from UniProt:

Catalytic activity: D-glucose(out) = D-glucose(in

Activity regulation: The uptake of glucose is inhibited by cytochalasin B and Phe-amide core-scaffold inhibitors GLUT-i1 and GLUT-i2 (PubMed:27078104). These inhibitors bind in the central cavity of the inward-open state and overlap the glucose-binding site (PubMed:27078104). Glucose uptake is increased in response to phorbol ester 12-O-tetradecanoylphorbol-13-acetate (TPA) treatment: TPA-induced glucose uptake requires phosphorylation at Ser-226 (PubMed:25982116).

Recommended name: Solute carrier family 2, facilitated glucose transporter member 1
