一般說明

盲肌样蛋白 1 (MBNL1) 是盲肌样蛋白家族成员。MBNL1参与前体mRNA的选择性剪接,并充当特定前体mRNA靶标的剪接激活或抑制剂。此蛋白含有四个C3H1型锌指结构域并与扩展的CUG重复序列RNA结合。在心肌、骨骼肌以及分化成肌细胞中,可观察到高表达水平的MBNL1。目前确知MBNL1参与 Ⅰ型强直性肌营养不良症 (DM1) 的发病机制。对于患有这种肌肉疾病的人来说,可用含有CUG三联体重复扩增的DMPK RNA隔离MBNL1 。

免疫原

对应于人MBNL1的全长重组蛋白。

應用

免疫细胞化学分析:
代表性批次的1:4稀释液在肌强直性营养不良细胞中检测到MBNL1。 数据由Wolfson Centre for Inherited Neuromuscular Disease的Ian Holt博士提供。
抗MBNL1抗体,克隆4A8是用于检测MBNL1的小鼠单克隆抗体,也称为肌盲样蛋白1,三重扩增RNA结合蛋白&已在WB、IP、ICC中得到验证。

品質

通过蛋白质印迹对HEK293细胞裂解物中的抗体进行了评估。

蛋白质印迹分析:用该抗体的1:10,000稀释液在10 µg HEK293细胞裂解液中检测MBNL1。

Myotonic dystrophy type 2 (DM2) is a genetically defined disease caused by a toxic expanded repeat of r(CCUG) [r(CCUG)exp], harbored in intron 1 of CCHC-type zinc-finger nucleic acid binding protein (CNBP) pre-mRNA. This r(CCUG)exp causes toxicity via a gain-of-function mechanism

The muscleblind-like (Mbnl) family of RNA-binding proteins plays important roles in muscle and eye development and in myotonic dystrophy (DM), in which expanded CUG or CCUG repeats functionally deplete Mbnl proteins. We identified transcriptome-wide functional and biophysical targets of Mbnl

RNA repeat expansions are responsible for more than 30 incurable diseases. Among them is myotonic dystrophy type 1 (DM1), the most common form of adult on-set muscular dystrophy. DM1 is caused by an r(CUG) repeat expansion [r(CUG)exp] located in the

Nuclear speckles are storage sites for small nuclear RNPs (snRNPs) and other splicing factors. Current ideas about the role of speckles suggest that some pre-mRNAs are processed at the speckle periphery before being exported as mRNA. In myotonic dystrophy type

Myotonic dystrophy Type 1 (DM1) is a rare genetic disease caused by the expansion of CTG trinucleotide repeats ((CTG)exp) in the 3' untranslated region of the DMPK gene. The repeat transcripts sequester the RNA binding protein Muscleblind-like protein 1 (MBNL1)
