Glycogen synthase kinase 3 beta, also known as GSK3B, is an enzyme that in humans is encoded by the GSK3B gene. In mice, the enzyme is encoded by the GSK-3β gene. Abnormal regulation and expression of GSK3β is associated with an increased susceptibility towards bipolar disorder.
Glycogen synthase kinase-3 (GSK-3) is a proline-directed serine-threonine kinase that was initially identified as a phosphorylating and an inactivating agent of glycogen synthase. Two isoforms, alpha (GSK3A) and beta, show a high degree of amino acid homology. GSK3B is involved in energy metabolism, neuronal cell development, and body pattern formation. It might be a new therapeutic target for ischemic stroke.
Homozygous disruption of the GSK-3β locus in mice results in embryonic lethality during mid-gestation. This lethality phenotype could be rescued by inhibition of tumor necrosis factor.
Two SNPs at this gene, rs334558 (-50T/C) and rs3755557 (-1727A/T), are associated with efficacy of lithium treatment in bipolar disorder.
Pharmacological inhibition of ERK1/2 restores GSK3β activity and protein synthesis levels in a model of tuberous sclerosis.
