描述：

CST公司的PhosphoPlus® Duets为研究蛋白的活化状态提供了一种方法，每一对包含针对靶蛋白活化状态和总蛋白的抗体。这些抗体是从CST特定领域的优秀产品中遴选出来的。糖原合酶激酶-3（GSK-3）最初被确认为是一种能在胰岛素的刺激下参与调节糖原合成的酶（1）。GSK-3是一个广泛表达的丝氨酸/苏氨酸蛋白激酶，可以磷酸化并抑制糖原合成酶的活性。GSK-3是PI3K/ Akt细胞存活通路上的一个关键下游分子，其活性可以被Akt介导的GSK-3α的Ser21位点和GSK-3β的Ser9位点的磷酸化抑制（2,3）。GSK-3不仅参与盘基网柄菌细胞命运的调控，而且是果蝇，爪蟾和哺乳动物发育过程中所需的Wnt信号通路的一个组成部分（4）。GSK-3还参与调节Cyclin D1 蛋白降解和亚细胞定位（5）。

Description

PhosphoPlus® Duets from Cell Signaling Technology (CST) provide a means to assess protein activation status. Each Duet contains an activation-state and total protein antibody to your target of interest. These antibodies have been selected from CST's product offering based upon superior performance in specified applications.

Background

Glycogen synthase kinase-3 (GSK-3) was initially identified as an enzyme that regulates glycogen synthesis in response to insulin (1). GSK-3 is a ubiquitously expressed serine/threonine protein kinase that phosphorylates and inactivates glycogen synthase. GSK-3 is a critical downstream element of the PI3 kinase/Akt cell survival pathway whose activity can be inhibited by Akt-mediated phosphorylation at Ser21 of GSK-3α and Ser9 of GSK-3β (2,3). GSK-3 has been implicated in the regulation of cell fate in Dictyostelium and is a component of the Wnt signaling pathway required for Drosophila, Xenopus, and mammalian development (4). GSK-3 has been shown to regulate cyclin D1 proteolysis and subcellular localization (5).
