Glucose transporter 1 (GLUT1), also known as solute carrier family 2, facilitated glucose transporter member 1 (SLC2A1), is a uniporter protein responsible for the transport of glucose in many cell types and across the blood-brain barrier.
What is the molecular weight of GLUT1? Is GLUT1 post-translationally modified?
There are two forms of GLUT1 transporter that differ in their molecular weight. The 45-kDa form is found in glial cells, while the 55-kDa form is present in the endothelial cells regulating glucose transport over the blood-brain and blood-tissue barriers (PMID: 9630522). N-glycosylation of asparagine at position 42 is the only known post-translation modification of GLUT1 (PMID: 3839598).
What is the subcellular localization of GLUT1?
Glucose transporters, including GLUT1, are multiple-pass integral membrane proteins. GLUT1 is present at the plasma membrane but is also a subject of recycling between plasma membrane and endosomes.
What molecules can be transported by GLUT1?
The main substrate of GLUT1 transport is glucose, but it can also transport galactose, mannose, glucosamine, and reduced ascorbate.
What is the tissue expression pattern of GLUT1?
GLUT1 is expressed by many cell types but the highest levels are observed in erythrocytes and in the central nervous system (astrocytes). GLUT1 is responsible for glucose transfer across the blood-brain and blood-tissue barriers, including placental transport.

Very clear staining in IHC in rat brain tissue (Wistar) at a concentration of 1:100, very well localised to blood vessels. Not tested yet at different concentrations

Staining of B cells from mice bone marrow after cytoplasmic permezbiliation. The cells were first fixed and permeabilized with intracellular fix and perm set from ebioscience and then stained with 1 µl/ million cells with Glut-1 antibody (21829-1-AP) during 50min After, a seconde staining was performed with 0,1µl/million cells of F(ab')2-Donkey anti-Rabbit IgG (H+L), PE, Secondary Antibody from invitrogen. In blue secondary antibody alone and in red primary (21829-1-AP) +secondary antibody
