描述：

Phospho-c-Abl (Tyr204) (C42B5) Rabbit mAb 兔单抗能检测Tyr204位点磷酸化的内源性 c-Abl 蛋白。这种抗体会与其他酪氨酸磷酸化的蛋白发生弱交叉反应。更多信息请参照CST的PhosphoScan®和LC-MS/MS技术平台，网址是www.phosphosite.org.该单克隆抗体通过使用合成的与人源c-Abl蛋白Tyr204位点周围残基相一致的磷酸化肽段免疫动物而获得。c-Abl原癌基因编码一个非受体蛋白酪氨酸激酶，该激酶在多细胞动物中普遍表达且高度保守。c-Abl蛋白分布于胞核以及胞质中，参与调节细胞增殖、分化、凋亡细胞粘附和应激反应(1-3)。在体内，通过整合素激活、PDGF刺激以及结合到c-Jun、Nck 和RFX1 蛋白上(2,4)等各种生理刺激，能使c-Abl激酶的活力提高。调节c-Abl蛋白激酶活力的体内机制目前尚不完全清楚。Tyr245位点位于SH2和催化区之间的连接区域，Abl蛋白家族在这个位点处都是保守的。Tyr245位点的磷酸化涉及到c-Abl激酶的活化（5）。另外，位于Abl蛋白的激酶活化环处的Tyr412位点，对激酶的活性也是必需的（6）。

c-Abl蛋白的Tyr204位点磷酸化是CST发现的，使用的是CST的PhosphoScan®和LC-MS/MS技术平台实现的，该磷酸化位点与另外一篇基于MS技术的文献中的一致 (7)

Species predicted to react based on 100% sequence homology: Mouse

Specificity / Sensitivity

Phospho-c-Abl (Tyr204) (C42B5) Rabbit mAb detects endogenous levels of c-Abl only when phosphorylated at Tyr204. This antibody may weakly cross-react with other tyrosine-phosphorylated proteins. For additional information please visit PhosphoSitePlus®, CST's modification site knowledgebase, at www.phosphosite.org.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Tyr204 of human c-Abl.

Background

The c-Abl proto-oncogene encodes a nonreceptor protein tyrosine kinase that is ubiquitously expressed and highly conserved in metazoan evolution. c-Abl protein is distributed in both the nucleus and the cytoplasm of cells. It is implicated in regulating cell proliferation, differentiation, apoptosis, cell adhesion and stress responses (1-3). c-Abl kinase activity is increased in vivo by diverse physiological stimuli including integrin activation, PDGF stimulation and binding to c-Jun, Nck and RFX1 (2,4). The in vivo mechanism of regulation of c-Abl kinase activity is not completely understood. Tyr245 is located in the linker region between the SH2 and catalytic domains. This positioning is conserved among Abl family members. Phosphorylation of Tyr245 is involved in the activation of c-Abl kinase (5). In addition, phosphorylation of Tyr412, which is located in the kinase activation loop of c-Abl, is required for kinase activity (6).

Phosphorylation of c-Abl on Tyr204 was identified at Cell Signaling Technology (CST) using PhosphoScan®, CST's LC-MS/MS platform for phosphorylation site discovery as well as another publication using MS technology (7).
