磷酸化非受体性蛋白酪氨酸激酶ETK抗体产品介绍 Tyrosine kinases are either receptor molecules, which contain transmembrane and extracellular domains, or nonreceptor proteins, which are located intracellularly. BMX[ETK] is a member of Bruton's tyrosine kinase family. It is expressed in haematopoetic, epithelial and endothelial cells and participates in multiple signal transduction pathways.
Function : Non-receptor tyrosine kinase that plays central butdiverse modulatory roles in various signaling processes involved inthe regulation of actin reorganization, cell migration, cellproliferation and survival, cell adhesion, and apoptosis.Participates in signal transduction stimulated by growth factorreceptors, cytokine receptors, G-protein coupled receptors, antigenreceptors and integrins. Induces tyrosine phosphorylation of BCAR1in response to integrin regulation. Activation of BMX by integrinsis mediated by PTK2/FAK1, a key mediator of integrin signalingevents leading to the regulation of actin cytoskeleton and cellmotility. Plays a critical role in TNF-induced angiogenesis, andimplicated in the signaling of TEK and FLT1 receptors, 2 importantreceptor families essential for angiogenesis. Required for thephosphorylation and activation of STAT3, a transcription factorinvolved in cell differentiation. Also involved in interleukin-6(IL6) induced differentiation. Plays also a role in programmingadaptive cytoprotection against extracellular stress in differentcell systems, salivary epithelial cells, brain endothelial cells,and dermal fibroblasts. May be involved in regulation ofendocytosis through its interaction with an endosomal proteinRUFY1. May also play a role in the growth and differentiation ofhematopoietic cells; as well as in signal transduction inendocardial and arterial endothelial cells.as in signal transduction inendocardial and arterial endothelial cells.
Subunit : Interacts with BCAR1, CAV1, MYD88, PTK2/FAK1, RUFY1,RUFY2, STAT3, TIRAP and TNFRSF1B.
Subcellular Location : Cytoplasm. Note=Localizes to the edges ofspreading cells when complexed with BCAR1.
Tissue Specificity : Highly expressed in cells with great migratorypotential, including endothelial cells and metastatic carcinomacell lines.
Post-translational modifications : Phosphorylated in response to protein I/II and to LPS.Phosphorylation at Tyr-566 by SRC and by autocatalysis leads toactivation and is required for STAT3 phosphorylation by BMX.
Similarity : Belongs to the protein kinase superfamily. Tyr protein kinase family.
TEC subfamily.

纯度:在实验的任何阶段,确定抗体溶液纯度的最简单方法是取一部分样本进行SDS-PAGE电泳。凝胶可用考马斯亮蓝染色(灵敏度为0.1—0.5ug/带)或银染(灵敏度1~l0ug/带)。
定量:如果抗体还不纯,有一个快捷的定量方法,即通过SDS-PAGE电泳分离出轻、重链,然后和已知的标准染色带比较。如果需要分析许多样本,用免疫测定法对抗体定量较容易。如果抗体是经过纯化的,可通过测蛋白总量代替上述两种方法,有一简单的方法,即紫外吸收法。磷酸化非受体性蛋白酪氨酸激酶ETK抗体的量可通过测280nm处的吸收值来测(10D大致相当于0.75mg/m1的纯化抗体)。
抗原结合活性:一般说来,纯化方法不会引起抗原结合活性的改变。用蛋白G或蛋白A树脂很少导致抗体活性丧失。然而,如果最终抗体产物的作用不如原来所预料的好,检测抗体纯化过程所丢失的活性就极为重要。用一系列滴定法比较纯化的抗体和其原材料的活性,以标定每一步中的总抗体量,这将有助于较好的估计通过纯化所丢失的活性。
