GLUT Transporters
Cards in this deck (15)
- 1GLUT1- RoleConstituative, responsible for basal uptake
- 2GLUT1- LocationAlmost every tissue
- 3GLUT1- Glucose Affinity2.5-8mM
- 4GLUT2- RolePrevents entry of glucose into certain cells to preserve it for when necessary
- 5GLUT2- LocationLiver and pancreatic B cells
- 6GLUT2- Glucose AffinityLow, at 15-20mM, but very high uptake in this range
- 7GLUT2- Role in LiverAllows glucose entry for storage when blood glucose levels are high enough
- 8GLUT2- Role in PancreasWhen glucose is high enough, enters beta cells and signals insulin release
- 9GLUT3- RoleCompliment GLUT1 uptake in highly active tissues
- 10GLUT3- LocationBrain
- 11GLUT4- RoleBasal insulin uptake (but is most effected by insulin)
- 12GLUT4- LocationSkeletal muscle
- 13GLUT4- Glucose Affinity5mM, but this changes with insulin secretion
- 14GLUT5- RoleFructose transporter
- 15GLUT5- LocationFound in the small intestine
