Specificity / Sensitivity

Phospho-FAK (Tyr925) Antibody detects endogenous levels of FAK only when phosphorylated at tyrosine 925.

磷酸化的FAK(酪氨酸925)抗体仅仅在酪氨酸925磷酸化时检测内源性FAK水平.

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Tyr925 of human FAK. Antibodies are purified by protein A and peptide affinity chromatography.

多克隆抗体由合成的磷酸化肽段免疫动物产生,该肽段与人FAK的925酪氨酸附近残基对应。抗体由蛋白A和肽段亲和层析纯化得到。

Western Blotting

Western Blotting

Western blot analysis of extracts from Jurkat cells, untreated or anti-CD3 antibody-treated (1 µg/ml for 10 minutes), using Phospho-FAK (Tyr925) Antibody (upper) or FAK antibody (lower).未处理或经过anti-CD3抗体处理(1µg/ml 10分钟 )的Jurkat细胞提取物,使用Phospho-FAK (Tyr925) 抗体(上)或FAk抗体(下)进行western blot分析。

Background

Focal adhesion kinase (FAK) is a widely expressed cytoplasmic protein tyrosine kinase involved in integrin-mediated signal transduction. It plays an important role in the control of several biological processes, including cell spreading, migration, and survival (1). Activation of FAK by integrin clustering leads to autophosphorylation at Tyr397, which is a binding site for the Src family kinases PI3K and PLCγ (2-5). Recruitment of Src family kinases results in the phosphorylation of Tyr407, Tyr576, and Tyr577 in the catalytic domain, and Tyr871 and Tyr925 in the carboxy-terminal region of FAK (6,7).

黏着斑激酶(FAK)是一类广泛表达在细胞质的蛋白酪氨酸激酶,涉及整合素调节的信号转导,它起着重要的作用,在控制包括细胞扩散迁移和存活的一系列生物过程(1)。整合素成簇激活FAK,导致酪氨酸397的自磷酸化,这是一个Src家族激酶PI3K和PLCγ的结合位点(2-5). Src家族激酶的招募导致Tyr407, Tyr576和 Tyr577在催化结构域的磷酸化,以及Tyr871和Tyr925在FAK羧基末端区域的磷酸化(6,7)。

Phosphorylation of Tyr925 creates a binding site for the Grb2/SH2 domain and triggers a Ras-dependent activation of the MAP kinase pathway (7).

酪氨酸925的磷酸化产生一个对Grb2/SH2结构域的结合位点,并激活一个Ras依赖的MAP激酶激活的途径(7).
