Glut4 phosphorylation
WebPhosphorylation of glucose to glucose 6-phosphate (G6P) by hexokinase is the first step in the intracellular metabolism of glucose, and this step seems to be a key determinant of muscle glucose uptake during the early stages of exercise ( 2,9 ). WebMar 28, 2024 · Further mechanism analysis found that inflammatory factors significantly reduced the phosphorylation (p-Akt) of Akt, two critical proteins of glucose metabolism in adipocytes, and the expression of GLUT4 protein downstream, resulting in impaired glucose utilization, while TSP intervention significantly increased the expression of these two ...

WebDec 1, 1993 · The molecular site of glimepiride action is related to GLUT4 phosphorylation/dephosphorylation, which may regulate glucose transporter activity and translocation. These in vitro findings implicate an additional mode of sulfonylurea action in the improvement of glucose tolerance of NIDDM patients. This content is only available … WebNov 8, 2024 · GLUT4 is encoded by the human gene SLC2A4. GLUT4 is an insulin-regulated protein that is primarily found in adipose tissues and striated muscles (skeletal and cardiac muscles). This protein was first identified by David James in 1988. The gene that encodes for this protein was cloned and mapped in 1989.
WebAug 5, 1993 · In adipocytes phosphorylation of GLUT4 is confined to the intracellular domain at the COOH-terminal region of the protein (12). Ser4=, which is located in this domain, was phosphorylated when vesicles containing GLUT4 were incu- bated with CAMP-dependent protein kinase (12). The present experiments were performed to investigate …
