GLUTs are integral membrane proteins that contain 12 membrane-spanning helices with both the amino and carboxyl termini exposed on the cytoplasmic side of the plasma membrane. GLUT proteins transport glucose and related hexoses according to a model of alternate conformation, [5] [6] [7] which predicts that the transporter exposes a single ...
Glucose uptake is the process by which glucose molecules are transported from the bloodstream into cells through specialized membrane proteins called glucose transporters, primarily via facilitated diffusion or active transport mechanisms: [1]
It is an integral membrane protein carrier with a hydrophilic interior, which allows it to bind to glucose. As GLUT 1 is a type of carrier protein, it will undergo a conformational change to allow glucose to enter the other side of the plasma membrane. [22] GLUT 1 is commonly found in the red blood cell membranes of mammals. [23]
The glucose transporter is specialized in transporting glucose specifically across the membrane. The GLUT proteins have several types of isoforms, each distributed in different tissues and exhibiting different kinetic properties. [16] Glucose transporter. GLUTs are integral membrane proteins composed of 12 α-helix membrane spanning regions. [16]

GLUT1 facilitates the transport of glucose across ...
This action creates a sodium concentration gradient across the cell membrane, with a lower concentration inside the cell compared to both the blood and the tubular lumen. [3] SGLT proteins utilize this sodium gradient to transport glucose across the apical membrane into the cell, even against the glucose concentration gradient.
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).
Glucose-6-phosphate translocase is a transmembrane protein providing a selective channel between the endoplasmic reticulum lumen and the cytosol. The enzyme is made up of three separate transporting subunits referred to as G6PT1 (subunit 1), G6PT2 (subunit 2) and G6PT3 (subunit 3).
