Background Information

Glucose transporter 2 (GLUT2), also known as solute carrier family 2, facilitated glucose transporter member 2 (SLC2A2), is a transporter protein regulating glucose transport across cell membranes in an insulin-independent manner.


What is the molecular weight of GLUT2? Is GLUT2 post-translationally modified?

GLUT2 can be N-glycosylated. The molecular weight of mature glycosylated GLUT2 transporter is between 55 and 65 kDa, but a minor 38-kDa form is often detected in hepatocytes that may represent a non-glycosylated or proteolytic product (PMID: 12101013).


What is the subcellular localization of GLUT2?

Glucose transporters, including GLUT2, are multiple-pass integral membrane proteins. GLUT2 is present at the plasma membrane but has also been reported to be present at intracellular membranes, including the endoplasmic reticulum (PMID: 12101013).


What molecules can be transported by GLUT2?

Although the main substrate of GLUT2 transport is glucose, it can also transport galactose, mannose, and fructose.


What is the tissue expression pattern of GLUT2?

GLUT2 is expressed in many cell types. High expression of GLUT2 is observed in hepatocytes, where GLUT2 mediates glucose uptake and release regulating glucose levels in blood, in intestinal cells, where it regulates glucose transport at the basolateral membrane and to a lesser extent from the apical membrane, and in the kidney proximal tubule, where it is involved in glucose reabsorption and is present at the basolateral membrane.

Balawant (Verified Customer) (07-25-2022)

This antibody I used and it is working great. I will recommend this antibody for Immunoblting.

  • Applications: Western Blot
  • Primary Antibody Dilution: 1:300
  • Cell Tissue Type: Caco2 cell and colon tissue

Susmita (Verified Customer) (04-13-2022)

This antibody is working nicely for my WB

  • Applications: Western Blot
  • Primary Antibody Dilution: WB: 1: 1500

Boyan (Verified Customer) (08-24-2021)

Not conclusive. This antibody primarily recognized a band at ~ 90 kd, which did not respond to a Glut2 siRNA treatment. It also weakly recognized a band at ~ 70 kd, which responded to de-glycosylation treatment.

  • Applications: Western Blot
