The relationships among fiber type, glucose transporter (GLUT-4) protein content, and glucose transport activity stimulated maximally with insulin and/or contractile activity were studied by use of the rat epitrochlearis (15% type I-20% type II2a-65% type IIb), soleus (84-16-0%), extensor digitorum longus (EDL, 3-57-40%), and flexor digitorum brevis (FDB, 7-92-1%) muscles.

In contrast, GLUT1 was eliminated by a mechanism involving the HCMV major immediate-early protein IE72. The HCMV-mediated induction of GLUT4 circumvents

Overview; Glucose transporters are membrane‐embedded proteins that mediate the uptake of glucose from the surrounding medium into the cell. Glucose is the main fuel for most cells, and its uptake is rate‐limiting for glucose utilization. For this reason, it is expected that glucose transport is tightly regulated. This gene encodes a major glucose transporter in the mammalian blood-brain barrier. The encoded protein is found primarily in the cell membrane and on the cell surface, where it can also function as a receptor for human T-cell leukemia virus (HTLV) I and II. 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.

Glucose transporter protein

Efficient substrate transport in mammalian kidney is provided by the concerted action of a low affinity high capacity and a high affinity low capacity Na +/glucose cotransporter arranged in series along kidney proximal tubules. There are two mechanisms for glucose transport across cell membranes. In the intestine and renal proximal tubule, glucose is transported against a concentration gradient by a secondary active transport mechanism in which glucose is cotransported with sodium ions. In all other cells, glucose transport is mediated by one or more of the members of the closely related GLUT family of glucose 2020-07-21 · Glucose transporters in the GLUT family use facilitative diffusion to transport glucose across the plasma membrane. They are enzyme proteins that can also transport galactose and fructose, in addition to glucose. GLUTs are expressed in a wide variety of cells, from red blood cells to liver to the brain.

Because glucose is a vital source of energy for all life, these transporters are present in all phyla.

Se hela listan på biologydictionary.net These data suggest that 1) GLUT 1 is the main glucose transporter protein isoform in human syncytiotrophoblast; 2) the glucose transport capacity for MVM is potentially approximately 20-fold higher than that of BM; 3) GLUT 1 densities may be regulated independently in MVM and BM; 4) the increase in surface area and the maintenance of a high GLUT 1 density can account for the increase in placental glucose transport in the latter part of pregnancy; and 5) fetal hypoglycemia in IUGR is not due Se hela listan på en.m.wikipedia.org 2021-01-29 · Glucose transporters are integral membrane proteins containing 12 membrane-spanning helix domains. This protein is the only member of the family that is regulated by insulin. While it is specific to muscle and fat tissue, other members of the glucose transporter family are specific to other tissues. For example, GLUT3, a high-affinity glucose Keywords: Glucose transporter protein, insulin, type 2 diabetes mellitus, flavonoids, glucose uptake.

Charles Heilig. The hexoses glucose, galactose and fructose serve as important dietary A total of 5 SGLUT proteins and 14 GLUT proteins have been identified to date.

This review focuses on recent advances on the biology of GLUT4. The sodium-glucose transport protein uses secondary active transport to move glucose into cells. They are active in intestinal cells and kidney cells, both of which need to move glucose into the body’s systems against its concentration gradient. The relationships among fiber type, glucose transporter (GLUT-4) protein content, and glucose transport activity stimulated maximally with insulin and/or contractile activity were studied by use of the rat epitrochlearis (15% type I-20% type II2a-65% type IIb), soleus (84-16-0%), extensor digitorum longus (EDL, 3-57-40%), and flexor digitorum brevis (FDB, 7-92-1%) muscles. The presence of glucose transport proteins is essential to supply glucose to the neurons and glia within the brain.

Glucose Transport and Protein Trafficking. Type Language Glucose transporter type 4 (GLUT-4), 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. glucose co-transport mechanism.

Glucose Transporter Proteins Glucose serves as a major source of energy for metabolic processes in mammalian cells. Since polar molecules cannot be transported across the plasma membrane, carrier proteins called glucose transporters are needed for cellular uptake.

This gene encodes a protein that helps transport glucose (a simple sugar) into cells where it is used as fuel. While glucose in the bloodstream can reach all body cells, it can't enter them--entering cells requires crossing a cell membrane, which glucose can't do on its own. Glucose from the bloodstream enters cells with the help of two proteins. The first, explains Dr. Sherwood, is called a glucose transporter, or GLUT protein.
