Specificity / Sensitivity

Phospho-c-Abl (Tyr245) (73E5) Rabbit mAb detects endogenous levels of c-Abl only when phosphorylated at tyrosine 245. The antibody does not cross-react with other activated protein tyrosine kinases.

Phospho-c-Abl (Tyr245) (73E5) Rabbit mAb 兔单抗能检测内源性Tyr245位点磷酸化的c-Abl蛋白水平。这种抗体不会与其他活化的蛋白酪氨酸激酶发生交叉反应。

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Tyr245 of human c-Abl.

该单克隆抗体通过使用合成的与人源c-Abl蛋白Tyr245位点周围残基相一致的磷酸化肽段免疫动物而获得。

Western Blotting

Western Blotting

Western blot analysis of CML-T1 and BV173 cell lysates, using Phospho-c-Abl (Tyr245) (73E5) Rabbit mAb. The phospho-specificity of the antibody was verified by treating the membrane with (+) (right) or without (-) (left) calf intestinal phosphatase (CIP) after Western transfer.

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).

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)。
