RNA结合蛋白是基因表达的动态转录后调节因子。因此,在给定的实验环境中鉴定mRNA结合蛋白是非常重要的。我们描述了一个程序,以丰富的直接聚(A)+RNA蛋白结合剂的4-硫代尿苷增强紫外交联和寡聚(dT)纯化。随后核酸酶介导的RNA结合蛋白(RBP)从mRNA的释放允许通过质谱法检测洗脱的蛋白质。此外,我们提供了一种比较的方法来检测生物刺激后RBP结合活性的差异。
RNA-binding proteins are dynamic posttranscriptional regulators of gene expression. Identification of mRNA-binding proteins in a given experimental setting is thus of great importance. We describe a procedure to enrich for direct poly(A)+RNA protein binders by 4-thiouridine-enhanced UV cross-linking and oligo(dT) purification. Subsequent nuclease-mediated release of RNA-binding proteins (RBPs) from mRNA allows for detection of eluted proteins by mass spectrometry. In addition, we provide a comparative approach to detect differences in RBP binding activity upon a biological stimulus.
