GSK3B

Introduction

Glycogen synthase kinase 3 beta, also known as GSK3B, is an enzyme that in humans is encoded by the GSK3B gene.[1][2] In mice, the enzyme is encoded by the GSK-3Ξ² gene.[3] Abnormal regulation and expression of GSK3Ξ² is associated with an increased susceptibility towards bipolar disorder.[4]

Function

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.[1] GSK3B is involved in energy metabolism, neuronal cell development, and body pattern formation.[5][6] It might be a new therapeutic target for ischemic stroke.

Loss of function mutations

Loss of function mutations

Homozygous disruption of the GSK-3Ξ² locus in mice results in embryonic lethality during mid-gestation.[3] This lethality phenotype could be rescued by inhibition of tumor necrosis factor.[3]

Signaling pathways

Signaling pathways

Pharmacological inhibition of ERK1/2 restores GSK3Ξ² activity and protein synthesis levels in a model of tuberous sclerosis.[7]
