描述：

Phospho-(Ser) 14-3-3 Binding Motif (4E2) Mouse mAb（鼠单抗）结合包含+2位脯氨酸和-3位精氨酸或赖氨酸的磷酸化丝氨酸肽段或蛋白。在ELISA中，该抗体可以识别多种包含磷酸化14-3-3结合基序的肽段，具有磷酸化特异性、并在很大程度上与周围氨基酸序列无关。该抗体与基序中包含磷酸化苏氨酸而非磷酸化丝氨酸的序列有弱相互作用，并与包含+1位有苯丙氨酸或-3位有精氨酸/赖氨酸的磷酸化丝氨酸肽段有弱相互作用。没有发现其能与相应的非磷酸化的序列或其它含磷酸化丝氨酸/苏氨酸/赖氨酸的基序发生交叉反应。Phospho-(Ser) 14-3-3 Binding Motif (4E2) Mouse mAb（鼠单抗）通过少量的变化和重叠的特异性补充了我们多克隆抗体Phospho-(Ser) 14-3-3 Binding Motif Antibody #9601。（美国专利号：6,441,140、6,982,318、7,259,022、7,344,714；U.S.S.N. 11,484,485；及其对应的国外相应专利）。该单克隆抗体用磷酸化丝氨酸14-3-3结合基序多肽免疫动物制备。14-3-3蛋白是参与调控细胞生存、凋亡、增殖和检查点控制的一组高度保守的蛋白家族（1-5）。14-3-3的生物调控由磷酸化依赖的蛋白-蛋白相互作用介导（6）。两种不同的包含磷酸化丝氨酸的基序在几乎所有的14-3-3结合蛋白中发现（7）。基序1（精氨酸/赖氨酸和丝氨酸在-3和-2位，磷酸化丝氨酸在0位，脯氨酸在+2位）在很多重要的调节蛋白包括Bad、cdc25C、FKHRL1、PKC和cRaf中发现（5-7）。Phospho-(Ser) 14-3-3 Binding Motif Polyclonal and (4E2) Monoclonal Antibody（结合基序多克隆和单克隆抗体）提供了发现和鉴定潜在的含此基序的14-3-3结合蛋白、及高通量药物发现的有力工具。

Specificity / Sensitivity

Phospho-(Ser) 14-3-3 Binding Motif (4E2) Mouse mAb binds peptides and proteins containing phospho-Ser surrounded by Pro at the +2 position and Arg/Lys at the -3 position. By ELISA, the antibody recognizes a wide range of peptides containing this phosphorylated 14-3-3 binding motif in a manner that is phospho-specific and largely independent of the surrounding amino acid sequence. The antibody weakly cross-reacts with sequences containing phospho-Thr instead of phospho-Ser in this motif, and with sequences containing phospho-Ser surrounded by Phe at the +1 position and Arg/Lys at the -3 position. No cross-reactivity is observed with corresponding nonphosphorylated sequences or with other phospho-Ser/Thr/Tyr containing motifs. Phospho-(Ser) 14-3-3 Binding Motif (4E2) Mouse mAb complements our polyclonal Phospho-(Ser) 14-3-3 Binding Motif Antibody #9601 by showing slightly different and overlapping specificity.

Background

The 14-3-3 proteins are a highly conserved family of proteins involved in the regulation of cell survival, apoptosis, proliferation and checkpoint control (1-5). Biological regulation by 14-3-3 is mediated through phosphorylation-dependent protein-protein interactions (6). Two different phospho-Ser-containing motifs are found within nearly all known 14-3-3 binding proteins (7). Motif 1 (Arg/Lys and Ser at positions -3 and -2, phospho-Ser at position 0, and Pro at position +2) is found in critical regulatory proteins including Bad, cdc25C, FKHRL1, PKC and c-Raf (5,7). Phospho-(Ser) 14-3-3 Binding Motif Polyclonal and (4E2) Monoclonal Antibodies provide powerful tools for the discovery and characterization of potential 14-3-3 binding proteins containing this motif and for high throughput drug discovery.
