基因信息

human ... TFEB(7942)

一般描述

转录因子EB(UniProt P19484;也称为bHLHe35,E类碱性螺旋-环-螺旋蛋白35)由人的TFEB(也称为αTFEB,BHLHE35,TCFEB)基因(基因ID 7942)编码。TFEB是碱性螺旋-环-螺旋(bHLH)亮氨酸拉链转录因子,在溶酶体生物发生的调节中起主要作用。TFEB还是对饥饿转录反应的主要参与者,并通过正向调节自噬体形成和自噬体-溶酶体融合来控制自噬。TFEB在Ser142处被mTORC1和ERK磷酸化,从而阻止了其核易位。mTORC1的药理抑制作用以及饥饿和溶酶体破坏可激活TFEB核易位。类似地,显示丝氨酸-苏氨酸激酶RIP1/RIPK1通过激活ERK抑制基础自噬流,进而使Ser142处的TFEB磷酸化,从而阻止参与自噬的基因产物的TFEB介导的转录。

特异性

该多克隆抗体仅在表达野生型TFEB的细胞的裂解物中检测到靶带,但在表达具有S142A突变的TFEB的细胞中未检测到靶带(Yonekawa, T., et al. (2015).Nat. Cell Biol. EMBO Rep.16(6):700-708).目标磷酸化位点在鼠(Ser141;UniProt Q9R210)和大鼠(Ser142;UniProt F7F5J1)TFEB蛋白中是保守的,但在人TFEB剪接亚型2(UniProt P19484-2)中不存在。

免疫原

对应于含有磷酸化Ser142的人TFEB序列的KLH偶联线性肽。
表位:pSer142。

应用

抗磷酸TFEB(Ser142)抗体是一针对磷酸TFEB的抗体,用于蛋白质印迹分析。
蛋白质印迹分析:在RIP1 shRNA处理后,代表性批次在对照HeLa细胞中检测到Ser142磷酸化的TFEB,但在RIP1缺陷型HeLa细胞中未检测到(Yonekawa, T., et al. (2015).Nat. Cell Biol. EMBO Rep.16(6):700-708)。
蛋白质印迹分析:在向营养缺乏的HEK293T转染子中添加氨基酸后,代表性批次检测到外源表达的野生型而非S142A突变体TFEB(具有3xFLAG标签)的Ser142磷酸化诱导(Settembre, C., et al. (2012).EMBO J. 31(5):1095-1108)。
蛋白印迹分析: 代表性批次在饥饿的HeLa转染子中检测到营养诱导的外源表达的TFEB(带有3xFLAG标签)的Ser142磷酸化。mTOR抑制剂Torin1(目录号475991)的预处理完全阻止了营养诱导的TFEB Ser142磷酸化,较弱的mTOR抑制剂雷帕霉素(目录号553210)部分抑制了Ser142磷酸化诱导(Settembre, C., et al. (2012).EMBO J. 31(5):1095-1108)。

质量

通过蛋白质印迹在TFEB转染的HEK293细胞的裂解物中进行了评估。

蛋白质印迹分析:该抗体的1:12500稀释液在转染的HEK293细胞的10 µg裂解物中检测到FLAG标记的人TFEB的Ser142磷酸化。

目标描述

观察值~60 kDa(带有3xFLAG标签)计算分子量为52.87 kDa。某些裂解液可能会出现未表征的条带。

Adult-onset neurodegenerative diseases are often accompanied by evidence of a chronic inflammation that includes activation of microglial cells and altered levels of brain cytokines. Aspects of this response are likely secondary reactions to neurodegeneration, but for many illnesses the inflammation
