Association of ribosomal proteins with nascent transcripts in S. cerevisiae.
Although it is generally accepted that transcription and translation are spatially separated in eukaryotes, a number of recent observations have called this belief into question. In particular, several studies have shown that parts of the translation machinery, including ribosomal proteins, can be found associated with sites of active transcription in metazoans. Here we describe results of chro...
متن کاملAssociation of individual hnRNP proteins and snRNPs with nascent transcripts
As they are transcribed, RNA polymerase II transcripts (hnRNAs or pre-mRNAs) associate with hnRNP proteins and snRNP particles, and the processing of pre-mRNA occurs within these ribonucleoprotein complexes. To better understand the relationship between hnRNP proteins and snRNP particles and their roles in mRNA formation, we have visualized them as they associate with nascent transcripts on the...
متن کاملNascent RNA transcripts facilitate the formation of G-quadruplexes
Recent discovery of the RNA/DNA hybrid G-quadruplexes (HQs) and their potential wide-spread occurrence in human genome during transcription have suggested a new and generic transcriptional control mechanism. The G-rich sequence in which HQ may form can coincide with that for DNA G-quadruplexes (GQs), which are well known to modulate transcriptions. Understanding the molecular interaction betwee...
متن کاملStructural organization of nascent transcripts and hnRN A moleeules
Comparisons ofrelative lengths oflampbrush loops, nascent RNP transcripts and hnRNA molecules from oocytes of amphibia with different C-values show that there is an increasing trend in loop, and transcriptional unit, length with increase in genome size but no increasing trend with respect to RN A contour length.The formation of duplex regions and circles in RNP fibrils indicates that RNA proces...
متن کاملVespucci: a system for building annotated databases of nascent transcripts
Global run-on sequencing (GRO-seq) is a recent addition to the series of high-throughput sequencing methods that enables new insights into transcriptional dynamics within a cell. However, GRO-sequencing presents new algorithmic challenges, as existing analysis platforms for ChIP-seq and RNA-seq do not address the unique problem of identifying transcriptional units de novo from short reads locat...
