Antisense Transcription Is Pervasive but Rarely Conserved in Enteric Bacteria
Noncoding RNAs, including antisense RNAs (asRNAs) that originate from the complementary strand of protein-coding genes, are involved in the regulation of gene expression in all domains of life. Recent application of deep-sequencing technologies has revealed that the transcription of asRNAs occurs genome-wide in bacteria. Although the role of the vast majority of asRNAs remains unknown, it is of...
متن کاملPervasive antisense transcription is evolutionarily conserved in budding yeast.
Antisense transcription, or transcription on the opposite strand of the same genomic locus as another transcript, has been observed in many organisms, including yeast. Several antisense transcripts are known to be conserved across various species of yeast, and a few antisense transcripts are associated with functional regulation of the sense transcript. We detect antisense transcription from ap...
متن کاملPervasive transcription: detecting functional RNAs in bacteria
Pervasive, or genome-wide, transcription has been reported in all domains of life. In bacteria, most pervasive transcription occurs antisense to protein-coding transcripts, although recently a new class of pervasive RNAs was identified that originates from within annotated genes. Initially considered to be non-functional transcriptional noise, pervasive transcription is increasingly being recog...
متن کاملRho and NusG suppress pervasive antisense transcription in Escherichia coli.
Despite the prevalence of antisense transcripts in bacterial transcriptomes, little is known about how their synthesis is controlled. We report that a major function of the Escherichia coli termination factor Rho and its cofactor, NusG, is suppression of ubiquitous antisense transcription genome-wide. Rho binds C-rich unstructured nascent RNA (high C/G ratio) prior to its ATP-dependent dissocia...
متن کاملHeamagglutinin Conserved Domain (HA2) Prepared in Prokaryotic System is Immunogenic in Mice but not Protective against Lethal Influenza Challenge
Background and Aims: Influenza vaccine production process is time-consuming with little-to-no cross-protection which requires annual adjustment. The construction of a universal vaccine to deal with the pandemics and epidemics which occasionally threat human population is the aim of many researches worldwide. Today, influenza vaccines are mostly against two major antigenic proteins, hemagglutini...
