GLUT transporter
GLUT transporters are an example of uniport carrier proteins[1]. They are integral membrane proteins that are responsible for the facilitated diffusion of glucose into cells such as erythrocytes (GLUT1) and liver cells (GLUT2)[2]. It can allow glucose to move into cells when concentration is high in the plasma (but low intracellular levels) or remove it from cells where plasma glucose concentration is low and extracellular levels are high. GLUT transporters are not active transporters, they make use of the chemical gradient that exists between the inside and outside of the plasma membrane[3].
