The functional role of long non-coding RNAs and epigenetics

Long non-coding RNAs (lncRNAs) are non-protein coding transcripts longer than 200 nucleotides. The post-transcriptional regulation is influenced by these lncRNAs by interfering with the microRNA pathways, involving in diverse cellular processes. The regulation of gene expression by lncRNAs at the epigenetic level, transcriptional and post-transcriptional level have been well known and widely studied. Recent recognition

RCas9: A Programmable RNA Editing Tool

newscenter.lbl.gov
– lcyarris
A powerful scientific tool for editing the DNA instructions in a genome can now also be applied to RNA, the molecule that translates DNA’s genetic instructions into the production of proteins. A team of researchers with Berkeley Lab and the University of California (UC) Berkeley has demonstrated a means by which the CRISPR/Cas9 protein complex can be programmed to recognize and cleave RNA at sequence-specific target sites. This finding has the potential to transform the study of RNA function by…  show all text

Rfam 12.0 is out | Xfam Blog

We are pleased to announce the release of Rfam 12.0!
This release contains some major changes when compared with previous releases of Rfam, so please take a minute to read our release notes. Rfam 12.0 is the first version of Rfam which is based on Infernal 1.1, and as such contains many significant changes. In particular, the curator-defined thresholds have all been manually altered to ensure compatability with Infernal 1.1. This means that many families have seen significant increases or decre…  show all text
