Functional micropeptides can be concealed within RNAs that appear to be noncoding. We discovered a conserved micropeptide, which we named myoregulin (MLN), encoded by a skeletal muscle-specific RNA annotated as a putative long noncoding RNA. MLN shares structural and functional similarity with phospholamban (PLN) and sarcolipin (SLN), which inhibit SERCA, the membrane pump that controls muscle ...
ADARs are a family of enzymes, present in all animals, that convert adenosine to inosine within double-stranded RNA (dsRNA). Inosine and adenosine have different base-pairing properties, and thus, editing alters RNA structure, coding potential and splicing patterns. The first ADAR substrates identified were edited in codons, and ADARs were presumed to function primarily in proteome diversificat...
EZH2, the catalytic component of polycomb repressive complex 2 (PRC2), is frequently overexpressed in human cancers and contributes to tumor initiation and progression, in part through transcriptional silencing of tumor suppressor genes. A number of noncoding RNAs (ncRNAs) recruit EZH2 to specific chromatin loci, where they modulate gene expression. Here, we used RNA immunoprecipitation sequenc...
The noncoding RNA database (ncRNAdb) was created as a source of information on RNA molecules, which do not possess protein-coding capacity. It is now widely accepted that, in addition to constitutively expressed, housekeeping or infrastructural RNAs, there is a wide variety of RNAs participating in mechanisms involved in regulation of gene expression at all levels of transmission of genetic inf...
Full-length cDNA clones of two Theiler murine encephalomyelitis virus (TMEV) strains, one highly virulent and the other less virulent, were constructed in the bacterial plasmid pGEMR-3. Transfection of BHK-21 cells with RNA transcribed from these cDNAs yielded progeny viruses with the exact in vitro growth phenotype and mouse neurovirulence pattern of the respective parental virus strains. RNA ...
T cells tell macrophages when to start making the toxic soup of lysosomal enzymes, reactive oxygen species, and nitric oxide that destroys intracellular pathogens. In 1983, Carl Nathan proved that this start signal comes in the form of the secreted cytokine IFNgamma.
