Quizplus · Accepted Answer

GLUT1 is the insulin transport protein that is found in most tissues in the body and is expressed regardless of insulin presence or absence in the blood. GLUT2 is mainly expressed in liver and pancreas and is involved in glucose sensing and insulin secretion. GLUT3 is mainly expressed in the brain and placenta and has high affinity for glucose. GLUT4 is mainly expressed in adipose tissue and skeletal muscle and is insulin-responsive, meaning its expression and function increase in response to insulin.
