Specificity / Sensitivity

Phospho-(Ser/Thr) Akt Substrate Antibody preferentially recognizes peptides and proteins containing phospho-Ser/Thr preceded by Lys/Arg at positions -5 and -3, in a manner largely independent of other surrounding amino acids. Some cross-reactivity is observed for peptides that contain phospho-Ser/Thr preceded by Arg/Lys at positions -3 and -2. No cross-reactivity is observed with the corresponding nonphosphorylated sequences or with other phospho-Ser/Thr-containing motifs. By ELISA, the antibody recognizes a wide range of phosphorylated Akt substrate peptides, and, by 2-D gel Western blot analysis, it recognizes a large number of proteins presumed to be Akt substrates. (U.S. Patent No's.: 6,441,140; 6,982,318; 7,259,022; 7,344,714; U.S.S.N. 11,484,485; and all foreign equivalents.)

Phospho-(Ser/Thr) Akt Substrate Antibody优先识别包含-5、-3位置上有赖氨酸/精氨酸的磷酸化丝氨酸/苏氨酸的内源性蛋白质,与周围序列无关。此抗体与-3位、-2位上是精氨酸/赖氨酸的磷酸化丝氨酸/苏氨酸的蛋白质有较弱的交叉反应。没有发现其能与相应的非磷酸化的序列或其它基序中的磷酸化丝氨酸/苏氨酸序列发生交叉反应。在ELISA中,其可以识别多种磷酸化Akt底物的肽段,在二维凝胶Western Blot中,其可以识别很多预测的Akt底物。(美国专利号:6,441,140、6,982,318、7,259,022、7,344,714;U.S.S.N. 11,484,485;及所有国外相应专利)

Source / Purification

An important class of kinases, referred to as Arg-directed kinases or AGC-family kinases, includes cAMP-dependent protein kinase (PKA), cGMP-dependent protein kinase (PKG), protein kinase C, Akt, and RSK. These kinases share a substrate specificity characterized by Arg at position -3 relative to the phosphorylated Ser or Thr (1,2). Akt plays a central role in mediating critical cellular responses including cell growth and survival, angiogenesis, and transcriptional regulation (3-5). While a number of Akt substrates are known (such as GSK-3, Bad, and caspase-9) many important substrates await discovery. Akt phosphorylates substrates only at Ser/Thr in a conserved motif characterized by Arg at positions -5 and -3 (6). Phospho-Akt substrate-specific antibodies from CST are powerful tools for investigating the regulation of phosphorylation by Akt and other Arg-directed kinases, as well as for high throughput kinase drug discovery.

精氨酸导向的激酶或AGC家族激酶是很重要的激酶,包括cAMP依赖的蛋白激酶(PKA)、cGMP依赖的蛋白激酶(PKG)、蛋白激酶C、Akt和RSK。这些激酶有相同的底物特异性,-3位上有精氨酸的丝氨酸和苏氨酸(1,2)。Akt在介导细胞内关键反应中扮演重要角色,包括细胞生长和生存、血管生成和转录调节(3-5)。目前已经发现一些Akt底物(如GSK-3、Bad、caspase-9),但还有很多重要底物等待发现。Akt磷酸化保守序列-5、-3位是精氨酸的丝氨酸/苏氨酸(6)。磷酸化Akt底物特异性抗体由Cell Signaling Technology公司研发,用于研究Akt磷酸化调节和精氨酸导向的激酶,也可以用于高通量药物发现。
