Specificity / Sensitivity

Phospho-(Ser/Thr) PDK1 Docking Motif (18A2) Mouse mAb detects phosphorylated serine or threonine that is surrounded by tyrosine or phenylalanine at the -1 and +1 positions and phenylalanine at the -4 position. It also recognizes peptides containing lysine instead of phenylalanine at the -4 position. This antibody does not cross-react with the nonphosphorylated PDK1 docking motifs or with other phosphorylated motifs. This antibody detects endogenous levels of phosphorylated proteins containing PDK1 docking motif, including phospho-Akt. (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) PDK1 Docking Motif (18A2) Mouse mAb鼠单抗识别-1、+1位是酪氨酸或苯丙氨酸,和-4位是苯丙氨酸的磷酸化丝氨酸或苏氨酸。它也能识别包含-4位不是苯丙氨酸而是赖氨酸的肽段。此抗体不与相应的非磷酸化PDK1结合基序或其它磷酸化基序发生交叉反应。该抗体识别内源性的含PDK1结合基序的磷酸化蛋白,包括磷酸化Akt。(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

Monoclonal antibody is produced by immunizing animals with peptides containing the PDK1 docking motif.

A hallmark of signal transduction pathways is the reversible phosphorylation of serine and threonine residues within specific sequences, or motifs, in target proteins. Specific signaling motifs include not only sequences that are recognized by protein kinases (1), but also those that are recognized by phosphorylation-dependent binding proteins such as 14-3-3 (2). These modular phosphoprotein interacting domains are critical elements in modulating, directing and amplifying intracellular communications. CST has pioneered the development of phospho-motif specific antibodies, which are invaluable tools for probing the complexity of phospho-regulatory pathways.


Many critical protein kinases can be regulated by phosphorylation at a specific serine or threonine in a hydrophobic motif (3). For example, Akt, a kinase that regulates cell survival, is activated by phosphorylation at Ser473, a site preceded by Phe at -4 and -1 and followed by Tyr at +1 (4). RSK2, p70 S6 kinase and certain PKC isoforms also contain a similar consensus phosphorylation motif. Phosphorylation of these motifs is required for binding to 3-phosphoinositide-dependent kinase 1 (PDK1) (5-7). Phospho-(Ser/Thr) PDK1 Docking Motif (18A2) Monoclonal Antibody is a powerful tool for the characterization of phosphorylated PDK1 docking motifs and the identification of new proteins with PDK1 docking motifs.

许多重要的蛋白激酶都能被疏水基序中特异性的丝氨酸、苏氨酸磷酸化所调节(3)。例如,Akt这种激酶可以调节细胞生存,其因在-4、-1位苯丙氨酸之后、+1位酪氨酸之前的Ser473位点的磷酸化而激活(4)。RSK2、p70 S6激酶和某些PKC亚型也包含类似的一致的磷酸化位点。这些基序的磷酸化为结合3-磷酸肌醇依赖性蛋白激酶1(PDK1)所必需(5-7)。Phospho-(Ser/Thr) PDK1 Docking Motif (18A2) Monoclonal Antibody是分析磷酸化PDK1结合基序和发现包含PDK1结合基序蛋白的有力工具。
