glucose transporter complex

Definition

Target type: cellularcomponent

A protein complex facilitating glucose transport into, out of or within a cell, or between cells. [GOC:bhm, PMID:15449578]

The glucose transporter complex (GLUT) is a multi-protein assembly responsible for facilitating glucose uptake across cell membranes. It's a dynamic structure that varies in composition and organization depending on the cell type and its metabolic needs. The core component of the complex is the glucose transporter protein itself, which is a transmembrane protein that binds and translocates glucose molecules. In addition to the transporter, the complex can include a variety of regulatory proteins, including scaffolding proteins, kinases, and phosphatases, which modulate the activity and localization of the transporter. The GLUT complex is often associated with specific membrane microdomains, such as lipid rafts, which provide a platform for its assembly and interaction with other signaling molecules. The precise composition and function of the GLUT complex are crucial for maintaining glucose homeostasis and regulating cellular metabolism. For instance, in muscle and adipose tissue, insulin signaling promotes the translocation of GLUT4, a key transporter, to the plasma membrane, increasing glucose uptake. In contrast, in neurons, the GLUT1 transporter plays a central role in supplying glucose for neuronal activity, and its function is influenced by neuronal activity itself. The dynamic nature of the GLUT complex, with its intricate interactions with other cellular components, highlights its crucial role in cellular energy metabolism and its significance in various physiological processes.'
