描述：

GSK3 Antibody Sampler Kit 试剂盒里的每一个抗体可以识别其特定的靶蛋白，不与其它家族成员发生交叉反应。单克隆抗体是采用合成的与人源GSK-3β的Ser9位周围序列，人源GSK-3α的Ser21位周围序列和人源GSK-3β的N末端序列以及GSK-3α对应的肽段免疫动物而生产的。GSK3 Antibody Sampler Kit 包含的一抗和二抗可以进行4次western blot实验。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）。

原厂资料：

Specificity / Sensitivity

Each antibody in the GSK-3 Antibody Sampler Kit recognizes only its specific target and does not cross-react with other family members.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues around Ser9 of human GSK-3β, residues around Ser21 of human GSK-3α, the N terminal sequence of human GSK-3β and to the sequence of human GSK-3α protein.

Description

The GSK-3 Antibody Sampler Kit contains primary and secondary antibodies to perform four Western blots with each antibody.

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).
