General description

Glycogen Synthase Kinase 3β (GSK3β) 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.

Application

Glycogen Synthase Kinase 3β (GSK3β) has been used
  • to study GSK3β cleavage by calpain
  • to perform motility assay on squid axoplasms
  • for the pre-incubation of progesterone receptor A during in vitro ubiquitination assay

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 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).

Unit Definition

One unit will transfer one pmole of phosphate from ATP to phosphatase inhibitor 2 per min at pH 7.5 at 30 °C.

Reconstitution

Reconstitution to 100 μl with deionized water produces a solution in 20 mM Tris, pH 7.5, 2 mM EDTA, 2 mM EGTA, 1 mM DTT, 5% sucrose, 0.1% Brij® L23, 1 μg/ml leupeptin, and 0.1 mM AEBSF.

Multifunctional ATP-citrate lyase kinase (ACLK) exhibits several properties that are similar to glycogen-synthase kinase-3 (GSK-3). The molecular cloning of two distinct mammalian GSK-3 cDNAs and a Drosophila melanogaster (fruitfly) homologue, zeste-white3sgg, has established the existence of a GSK-3 subfamily. A

Previously, tau protein kinase I/glycogen synthase kinase-3 beta/kinase FA(TPKI/GSK-3 beta/FA) was identified as a brain microtubule-associated tau kinase possibly involved in the Alzheimer disease-like phosphorylation of tau. In this report, we find that the TPKI/GSK-3 beta/FA can be stimulated to

Although GSK-3 activity can be regulated by phosphorylation and through interaction with GSK-3-binding proteins, here we describe N-terminal proteolysis as a novel way to regulate GSK-3. When brain extracts were exposed to calcium, GSK-3 was truncated, generating two fragments of
