Glycogen synthase kinase-3 beta, (GSK-3 beta), is an enzyme that in humans is encoded by the GSK3B gene.^[5][6] In mice, the enzyme is encoded by the Gsk3b gene.^[7] Abnormal regulation and expression of GSK-3 beta is associated with an increased susceptibility towards bipolar disorder.^[8]

Function

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.^[5] GSK3B is involved in energy metabolism, neuronal cell development, and body pattern formation.^[9][10] It might be a new therapeutic target for ischemic stroke.

Disease relevance

Homozygous disruption of the Gsk3b locus in mice results in embryonic lethality during mid-gestation.^[7] This lethality phenotype could be rescued by inhibition of tumor necrosis factor.^[7]

Two SNPs at this gene, rs334558 (-50T/C) and rs3755557 (-1727A/T), are associated with efficacy of lithium treatment in bipolar disorder.^[11]

Signaling pathways

Pharmacological inhibition of ERK1/2 restores GSK-3 beta activity and protein synthesis levels in a model of tuberous sclerosis.^[12]

Interactions

GSK3B has been shown to interact with:

• KIAA1211L^[13]
• ATP2A2^[14]
