Specificity / Sensitivity

Phospho-Akt Substrate (RXXS*/T*) (110B7E) Rabbit mAb (Magnetic Bead Conjugate) recognizes peptides and proteins containing phospho-Ser/Thr preceded by Arg at the -3 position. There is some preference observed for peptides that contain phospho-Ser/Thr preceded by Arg at both positions -5 and -3. (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-Akt Substrate (RXXS*/T*) (110B7E) Rabbit mAb (Magnetic Bead Conjugate)识别包含-3位上有精氨酸的磷酸化丝氨酸/苏氨酸的肽段和蛋白。此抗体与包含-5、-3位上有精氨酸的磷酸化丝氨酸/苏氨酸的肽段有部分的交叉反应。(美国专利号:6,441,140、6,982,318、7,259,022、7,344,714;U.S.S.N. 11,484,485;及其对应的国外部分)

Source / Purification

Monoclonal antibody is produced by immunizing animals with synthetic phospho-Akt substrate peptides.



This Cell Signaling Technology antibody is immobilized by the covalent reaction of hydrazinonicotinamide-modifed antibody with formylbenzamide-modified magnetic bead. Phospho-Akt Substrate (RXXS*/T*) (110B7E) Rabbit mAb (Magnetic Bead Conjugate) is useful for immunoprecipitation of phosphorylated Akt substrate proteins.

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,与磷酸化的丝氨酸和苏氨酸相关(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磷酸化保守序列中精氨酸-5、-3位置的丝氨酸/苏氨酸(6)。磷酸化Akt底物特异性抗体由Cell Signaling Technology公司提供,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。
