- W3046248967 abstract "Regulation of gene expression by the act of noncoding transcription may connect environmental sensing and regulation in eukaryotes. The act of lncRNA transcription affects DNA biology. Intragenic ncDNA elements regulate host gene expression by a variety of mechanisms, including repression, activation and transcript isoform selection. Termination of RNAPII transcription represents a key step in transcriptional regulation tightly linked to noncoding transcription. RNA polymerase (RNAP)II frequently transcribes non-protein-coding DNA sequences in eukaryotic genomes into long noncoding RNA (lncRNA). Distinct molecular mechanisms linked to the position of lncRNA relative to the coding gene illustrate how noncoding transcription controls gene expression. Here, we focus on the impact of the act of lncRNA transcription on nearby functional DNA units. We review the biological significance of the act of lncRNA transcription on DNA processing, highlighting common themes, such as mediating cellular responses to environmental changes. This review combines the background of chromatin signaling with examples in several organisms to clarify when functions of ncDNA can be interpreted through the act of RNAPII transcription.
