A methylation-switchable conformational probe for the sensitive and selective detection of RNA demethylase activity.

چکیده
We describe a novel methylation-sensitive nucleic acid (RNA) probe which switches conformation according to its methylation status. When combined with a differential scanning fluorimetry technique, it enables highly sensitive and selective detection of demethylase activity at a single methylated-base level. The approach is highly versatile and may be adapted to a broad range of RNA demethylases.

متن کاملAn amine/imine functionalized microporous MOF as a new fluorescent probe exhibiting selective sensing of Fe3+ and Al3+ over mixed metal ions
Nowadays metal-organic frameworks with multiple luminescent centers are very fascinating as multifunctional luminescent material because of their luminescence properties, which could be systematically tuned by deliberate use of organic ligands and metal ions. In this research, we explored a microporous mixed-ligand MOF for highly selective and sensitive detection of metal ions. A two-fold inter...
متن کاملMethylation-Sensitive Expression of a DNA Demethylase Gene Serves As an Epigenetic Rheostat
Genomes must balance active suppression of transposable elements (TEs) with the need to maintain gene expression. In Arabidopsis, euchromatic TEs are targeted by RNA-directed DNA methylation (RdDM). Conversely, active DNA demethylation prevents accumulation of methylation at genes proximal to these TEs. It is unknown how a cellular balance between methylation and demethylation activities is ach...
متن کاملP-202: Reduced Expression of JMJD1A Histone Demethylase Gene in Testis Tissues of Infertile Men Referred to Royan Institute
Background: Epigenetic modifications are involved in different cellular processes through regulating chromatin dynamics. histone methylation is an important modification that can be dynamically regulated by histone methyltransferase and histone demethylase enzymes. JMJD1A (also known as JHDM2A and KDM3A) is a histone demethylase specific for H3K9me2/me1. JMJD1A is a key epigenetic regulator tha...
