Electrophoretic Mobility Shift Assay: Analyzing Protein – Nucleic Acid Interactions
The characterization of protein-nucleic acid interactions is essential not only for understanding the wide range of cellular processes they are involved in, but also the mechanisms underlying numerous diseases associated with the breakdown of regulatory systems. These include, but are far from being limited to, cell cycle disorders such as cancer and those caused by pathogenic agents that rely ...
متن کاملElectrophoretic Mobility Shift Assay (EMSA).
Transcriptional regulation of gene expression is controlled through the binding of sequence-specific DNA-binding proteins (transcription factors) to the regulatory regions of genes. The exact gene expression program of a cell is determined by the spectrum of transcription factors present with the nucleus of a cell. The presence of these factors is dependent upon the cell type being examined and...
متن کاملElectrophoretic mobility shift assays for RNA-protein complexes.
The electrophoretic mobility shift assay (EMSA), or gel mobility shift assay, is a popular and powerful technique for the detection of RNA-protein interactions. It relies on the fact that naked RNA has certain mobility on nondenaturing gels, but if the RNA is bound by protein, the mobility of the RNA is reduced. Therefore, the binding of protein results in a characteristic upward shift of the R...
متن کاملAnalysis of factor interactions with RNA polymerase II elongation complexes using a new electrophoretic mobility shift assay
The elongation phase of transcription by RNA polymerase II (RNAP II) is controlled by a carefully orchestrated series of interactions with both negative and positive factors. However, due to the limitations of current methods and techniques, not much is known about whether and how these proteins physically associate with the engaged polymerases. To gain insight into the detailed mechanisms invo...
متن کاملElectrophoretic mobility shift assays for the analysis of DNA-protein interactions.
Electromobility shift assay is a simple, efficient, and rapid method for the study of specific DNA-protein interactions. It relies on the reduction in the electrophoretic mobility conferred to a DNA fragment by an interacting protein. The technique is suitable to qualitative, quantitative, and kinetic analyses. It can also be used to analyze conformational changes.
