CC -!- FUNCTION: Facilitative glucose transporter, which is responsible for
CC constitutive or basal glucose uptake. Has a very broad substrate
CC specificity; can transport a wide range of aldoses including both
CC pentoses and hexoses. Most important energy carrier of the brain:
CC present at the blood-brain barrier and assures the energy-independent,
CC facilitative transport of glucose into the brain (By similarity). In
CC association with BSG and NXNL1, promotes retinal cone survival by
CC increasing glucose uptake into photoreceptors (By similarity).
CC {ECO:0000250|UniProtKB:P11166, ECO:0000250|UniProtKB:P46896}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=D-glucose(out) = D-glucose(in); Xref=Rhea:RHEA:60376,
CC ChEBI:CHEBI:4167; Evidence={ECO:0000250|UniProtKB:P11166};
CC -!- ACTIVITY REGULATION: The uptake of glucose is inhibited by cytochalasin
CC B. Glucose uptake is increased in response to phorbol ester 12-O-
CC tetradecanoylphorbol-13-acetate (TPA) treatment: TPA-induced glucose
CC uptake requires phosphorylation at Ser-226.
CC {ECO:0000250|UniProtKB:P11166}.
CC -!- SUBUNIT: Found in a complex with ADD2, DMTN and SLC2A1. Interacts (via
CC C-terminus cytoplasmic region) with DMTN. Interacts with SNX27; the
CC interaction is required when endocytosed to prevent degradation in
CC lysosomes and promote recycling to the plasma membrane. Interacts with
CC GIPC (via PDZ domain). Interacts with STOM. Interacts with SGTA (via
CC Gln-rich region) (By similarity). Interacts with BSG (By similarity).
CC {ECO:0000250|UniProtKB:P11166, ECO:0000250|UniProtKB:P11167}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250|UniProtKB:P11166};
CC Multi-pass membrane protein {ECO:0000255}. Photoreceptor inner segment
CC {ECO:0000250|UniProtKB:P17809}.
CC -!- PTM: Phosphorylation at Ser-226 by PKC promotes glucose uptake by
CC increasing cell membrane localization. {ECO:0000250|UniProtKB:P11166}.
CC -!- SIMILARITY: Belongs to the major facilitator superfamily. Sugar
CC transporter (TC 2.A.1.1) family. Glucose transporter subfamily.
CC {ECO:0000305}.
