https://www.selleckchem.com/products/sn-38.html Transcriptional fidelity depends on accurate promoter selection and initiation from the correct sites. In yeast, H3K36me3-mediated recruitment of the Rpd3S HDAC complex to gene bodies suppresses spurious transcription initiation. Here we describe an equivalent pathway in metazoans. PWWP2A/B is an H3K36me3 reader that forms a stable complex with HDAC1/2. We used CAGE-seq to profile all transcription initiation sites in wild-type mESCs and cells lacking PWWP2A/B. Loss of PWWP2A/B enhances spurious initiation from intragenic sites present in wild-type mESCs, and this effect is associated with increased levels of initiating Pol-II and histone acetylation. Spurious initiation events in Pwwp2a/b DKO mESCs do not overlap in genomic location or chromatin features with spurious sites that arise in Dnmt3b KO mESCs, previously reported to function in the suppression of intragenic transcriptional initiation, suggesting these pathways function cooperatively in maintaining the fidelity of transcription initiation in metazoans.In contrast to enormous progresses in electrode active materials, little attention has been paid to electrode sheets despite their crucial influence on practical battery performances. Here, as a facile strategy to address this issue, we demonstrate nanofibrous conductive electrode binders based on deoxyribonucleic acid (DNA)-wrapped single-walled carbon nanotubes (SWCNT) (denoted as DNA@SWCNT). DNA@SWCNT binder allows the removal of conventional polymeric binders and carbon powder additives in electrodes. As a proof of concept, high-capacity overlithiated layered oxide (OLO) is chosen as a model electrode active material. Driven by nanofibrous structure and DNA-mediated chemical functionalities, the DNA@SWCNT binder enables improvements in the redox reaction kinetics, adhesion with metallic foil current collectors, and chelation of heavy metal ions dissolved from OLO. The resulting OLO cathode exhibits a fast c
