What is Glucose Transporter?

Glucose transporters (GLUTs) are a family of proteins that facilitate the transport of glucose and other hexoses across cell membranes. They play a crucial role in regulating glucose homeostasis in the body, allowing cells to uptake glucose from the bloodstream for energy production. Different types of GLUTs are expressed in various tissues, each with specific functions and regulatory mechanisms. For instance, GLUT4 is insulin-responsive and predominantly found in adipose and muscle tissues, while GLUT1 is widely distributed and responsible for basal glucose uptake.
