描述 | Phospho-(Ser/Thr) Kinase Substrate Antibody Sampler Kit contains 40 µl of each polyclonal primary antibody [Phospho-(Ser) PKC Substrate Antibody, Phospho-(Ser) CDKs Substrate Antibody and Phospho-(Ser/Thr) ATM/ATR Substrate Antibody], 40 µl each of Phospho-(Ser/Thr) Akt Monoclonal Substrate Antibody and Phospho-(Ser/Thr) PKA Substrate Antibody and 40 µl of Phospho-(Thr) MAPK/CDK Substrate mAb. |
目标/特异性 | Each antibody detects endogenous levels of phospho-(Ser/Thr) proteins of specific kinase substrate groups. Phospho-(Ser/Thr) Akt Substrate (110B7E) Rabbit mAb preferentially recognizes peptides and proteins containing phospho-serine/threonine preceded by arginine at positions -5 and -3, in a manner largely independent of the surrounding amino acid sequence. Some cross-reactivity is observed for peptides that contain phospho-serine/threonine preceded by arginine at position -3 . No cross-reactivity is observed with the corresponding nonphosphorylated sequences or with other phospho-serine/threonine-containing motifs. By ELISA, the antibody recognizes a wide range of peptides with phospho-threonine or Phospho-serine with arginine at -3 and -5 position. Phospho-(Ser) PKC Substrate Antibody detects endogenous levels of many cellular proteins only when phosphorylated at serine residues surrounded by Arg or Lys at the -2 and +2 positions and a hydrophobic residue at the +1 position. The antibody does not cross-react with nonphosphorylated serine residues, with phospho-threonine in the same motif, or with phospho-serine in other motifs. Phospho-PKA Substrate (RRXS*/T*) (100G7E) Rabbit mAb detects peptides and proteins containing a phospho-Ser/Thr residue with arginine at the -3 and -2 positions. It is a useful tool in identifying new substrates of PKA. The antibody recognizes other -3 arginine-bearing phospho-Ser/Thr peptides, such as substrate motifs for Akt and PKC, to a lesser extent. It does not recognize the nonphosphorylated substrate motif peptides. Phospho-(Thr) MAPK/CDK Substrate Mouse mAb detects phospho-threonine only when followed by proline. It reacts with proteins/peptides phosphorylated on the Thr-Pro motif in an otherwise highly context-independent fashion. The antibody does not cross-react with phospho-threonine in the absence of an adjacent proline. The antibody does not cross-react with phospho-tyrosine, but does react with some phospho-serine peptides containing the phospho-serine-proline motif (e.g., phospho-Elk-1). Phospho-(Ser) CDKs Substrate Antibody detects phospho-serine in a (K/R)(S*)PX(K/R) motif. The antibody is phospho-specific but does not recognize phospho-serine in the absence of the CDK motif. The antibody does not cross-react with phospho-threonine- or phospho-tyrosine-containing peptides/proteins. Phospho-(Ser/Thr) ATM/ATR Substrate Antibody detects endogenous levels of proteins containing the ATM/ATR substrate motif. This antibody preferentially binds peptides and proteins that contain phospho-Ser/Thr preceded by Leu or similar hydrophobic amino acids at the -1 position and followed by Gln at the +1 position. The antibody does not cross-react with corresponding nonphosphorylated sequences or with other phospho-Ser/Thr-containing motifs. |

背景 | Phospho-(Ser/Thr) kinases and phosphatases play critical roles in a wide range of biological processes. Each phospho-(Ser/Thr) kinase phosphorylates serine or threonine within a specific motif. Akt phosphorylates substrates at a serine or threonine only in a conserved motif characterized by arginine at positions -5 and -3 (1). Conventional PKC isozymes phosphorylate substrates containing serine or threonine, with arginine or lysine at the -3, -2 and +2 positions, and a hydrophobic amino acid at position +1 (2,3). A consensus phosphorylation site of PKA is serine or threonine with arginine at the -2 and -3 positions (3). The MAPK and CDK families of serine/threonine protein kinases phosphorylate threonine or serine followed by proline residue (3-5).The consensus amino acid sequence for CDK substrate is (K/R)(S*)PX(K/R), where denotes any one of the 20 amino acids and S* is the phosphorylation site (6-8). ATM and the related kinase ATR phosphorylate serine or threonine in an S*/T*Q motif (9,10). Antibodies specific to particular kinase substrates are invaluable reagents in determining kinase activity and identifying potential new kinase substrates. CST has developed antibodies that recognize phosphorylated serine or threonine within the context of a protein motif that is phosphorylated by Akt, PKC, PKA, MAPK/CDK, CDKs or ATM/ATR. As shown by peptide pairing ELISA, each phospho-(Ser/Thr) kinase substrate antibody in this sampler kit is specific to its kinase substrate motif. |
