| Application: | GSK3β, active, His tagged human has been used as an incubating medium during in vitro hyperphosphorylation of tau protein. |
| Biochem/physiol Actions: | Glycogen Synthase Kinase 3β (GSK3β) is responsible for rapid cyclin D1 turnover by phosphorylating it on Thr-286. It functions as a negative regulator of Wnt signaling during embryonic development and cell proliferation in adult tissues. This protein phosphorylates and regulates multiple proteins, such as glycogen synthase, insulin receptor substrate-1, axin and APC (adenomatous polyposis coli). This protein is also shown to interact with multiple proteins which are linked with Alzheimer’s disease (AD). |
| Biochem/physiol Actions: | GSK3β is a serine-threonine protein kinase that was originally identified as the kinase that phosphorylates and inhibits glycogen synthase.GSK3β is ubiquitously present in human tissues and implicated in the regulation of several physiological processes, including the control of glycogen and protein synthesis by insulin and modulation of the transcription factors AP-1 and CREB. Transient transfection of human GSK3β into Chinese hamster ovary cells stably transfected with individual human tau isoforms leads to hyperphosphorylation of tau at all the sites investigated with phosphorylation-dependent anti-tau antibodies. |
| General description: | Research area: Cellsignalling. GSK3B (glycogen synthase kinase 3β) is one of the two isoforms of GSK3 enzyme, both of which are encoded by different genes. This protein is predominantly cytoplasmic, but is also found to be localized to nucleus and mitochondria. It is a protein-serine kinase. This protein contains a protein kinase domain in its core, and is composed of 482 amino acids with a molecular weight of 46,712Da. It shows a wide range of tissue expression with the highest expression in brain. |
