Glycogen synthase kinase-3; Glycogen synthase kinase 3

糖原合酶激酶 3 (GSK-3) 是一种多功能丝氨酸/苏氨酸激酶,由两种亚型组成,即 α 和 β。它是受体酪氨酸激酶、细胞因子和 Wnt 信号通路的高度保守负调节剂。这些通路的刺激会抑制 GSK-3 调节各种下游效应因子,包括转录因子、营养传感器、糖原合成、线粒体功能、昼夜节律和细胞命运。GSK-3 还调节响应 T 细胞受体激活的选择性剪接,最近的磷酸化蛋白质组学研究表明,多种剪接因子和 RNA 生物合成调节因子以 GSK-3 依赖的方式进行磷酸化。

GSK-3 的功能障碍或异常活动会导致多种疾病,如阿尔茨海默病 (AD) 和其他神经退行性疾病,以及其他类型的疾病,如糖尿病、心血管疾病和癌症。GSK-3 还与针对病原体的先天免疫反应有关,这使得 GSK-3 成为治疗干预的绝佳靶点。

Glycogen synthase kinase 3 (GSK-3) is a multifunctional serine/threonine kinase consisting of two isoforms, alpha and beta. It is a highly conserved negative regulator of receptor tyrosine kinase, cytokine, and Wnt signaling pathways. Stimulation of these pathways inhibits GSK-3 to modulate diverse downstream effectors that include transcription factors, nutrient sensors, glycogen synthesis, mitochondrial function, circadian rhythm, and cell fate. GSK-3 also regulates alternative splicing in response to T-cell receptor activation, and recent phosphoproteomic studies have revealed that multiple splicing factors and regulators of RNA biosynthesis are phosphorylated in a GSK-3-dependent manner.

The malfunction or aberrant activity of GSK-3 leads to several of disorders, such as Alzheimer's disease (AD) and other neurodegenerative pathologies, and other type of diseases as diabetes, cardiovascular disorders and cancer. GSK-3 is also related to innate immune response against pathogens, which makes GSK-3 an excellent target for therapeutic intervention.

Glycogen synthase kinase 3 (GSK-3) is a multifunctional serine/threonine kinase found in all eukaryotes. GSK-3 is one of the few signaling mediators that play central roles in a diverse range of signaling pathways, including those activated by Wnt, PI3K, growth factors, cytokines, and ligands for G protein-coupled receptors. The PI3K pathway is known for regulating metabolism, cell growth, and cell survival. The PI3K activity is stimulated by diverse oncogenes and growth factor receptors. PI3K-mediated production of PIP3 leads to the activation of Akt. The activation of Akt leads to the phosphorylation of GSK-3, which is active in resting cells, but is inactivated by the phosphorylation. The GSK-3 has been linked to the regulation of an assembly of transcription factors, including β-catenin, NF-κB, c-Jun, CREB, and STAT. Thus, the altered activity of GSK-3 causes various effects on cytokine expression. 

 

In the absence of Wnt signaling, β-catenin is phosphorylated by CK1 and GSK-3. This phosphorylation leads to recognition by β-TrCP, leading to the ubiquitylation of β-catenin and degradation by the proteasome. Upon binding of a lipid-modified Wnt protein to the receptor complex, a signaling cascade is initiated. LRP is phosphorylated by CK1/CK2 and GSK-3, and Axin is recruited to the plasma membrane. The kinases in the β-catenin destruction complex are inactivated and β-catenin translocates to the nucleus to form an active transcription factor complex with TCF, leading to transcription of a large set of target genes.

 

Some endogenous growth factors could bind to and activate the tyrosine kinase receptor. This facilitates the recruitment of other proteins (SHC, SOS), which results in the activation of the ERK-MAPK cascade and the inhibition of GSK-3. GSK-3 exerts many cellular effects: it regulates cytoskeletal proteins, and is important in determining cell survival/cell death. GSK-3 has also been identified as a target for the actions of lithium. GSK-3 can inhibit glycogen synthase, the enzyme that catalyzes the transfer of glucose from UDPG to glycogen[1][2].
