Glucose transporters are a wide group of membrane proteins that facilitate the transport of glucose across the plasma membrane, a process known as facilitated diffusion. Because glucose is a vital source of energy for all life, these transporters are present in all phyla .
Method of glucose uptake differs throughout tissues depending on two factors; the metabolic needs of the tissue and availability of glucose.The two ways in which glucose uptake can take place are facilitated diffusion (a passive process) and secondary active transport (an active process which on the ion-gradient which is established through the hydrolysis of ATP, known as primary active ...

SLC5A4, also known as SGLT3, is a member of the sodium-glucose cotransporter family. Unlike SGLT1 and SGLT2, which are efficient glucose transporters, SGLT3 functions primarily as a glucose sensor rather than a transporter. It has a low affinity for glucose and does not significantly contribute to glucose transport across cell membranes.
Once glucose enters the cell, the first step is phosphorylation of glucose by a family of enzymes called hexokinases to form glucose 6-phosphate (G6P). This reaction consumes ATP, but it acts to keep the glucose concentration inside the cell low, promoting continuous transport of blood glucose into the cell through the plasma membrane transporters.
Glucose transporter type 4 (GLUT4), also known as solute carrier family 2, facilitated glucose transporter member 4, is a protein encoded, in humans, by the SLC2A4 gene. GLUT4 is the insulin -regulated glucose transporter found primarily in adipose tissues and striated muscle (skeletal and cardiac).
When the insulin binds to these alpha subunits, 'glucose transport 4' (GLUT4) is released and transferred to the cell membrane to regulate glucose transport in and out of the cell. With the release of GLUT4, the allowance of glucose into cells is increased, and therefore the concentration of blood glucose might decrease.
Transports glucose-6-phosphate from the cytoplasm to the lumen of the endoplasmic reticulum. Forms with glucose-6-phosphatase the complex responsible for glucose production through glycogenolysis and gluconeogenesis. Hence, it plays a central role in homeostatic regulation of blood glucose levels. Glycogen storage disease type I [37] FLVCR1: Q9Y5Y0
