Glucose Transporter Type 2
Glucose Transporter Type 2 (GLUT2) is a protein that facilitates the transport of glucose and other sugars across cell membranes. It is primarily found in the liver, pancreas, kidneys, and intestines. GLUT2 plays a crucial role in regulating blood sugar levels by allowing glucose to enter cells when needed, especially after meals.
In the pancreas, GLUT2 helps in sensing blood glucose levels, which triggers insulin release from beta cells. This process is vital for maintaining energy balance in the body. Dysfunction in GLUT2 can lead to issues such as diabetes, highlighting its importance in metabolic health.
