Quadruplex-forming sequences occupy discrete regions inside plant LTR retrotransposons
Retrotransposons with long terminal repeats (LTR) form a significant proportion of eukaryotic genomes, especially in plants. They have gag and pol genes and several regulatory regions necessary for transcription and reverse transcription. We searched for potential quadruplex-forming sequences (PQSs) and potential triplex-forming sequences (PTSs) in 18 377 full-length LTR retrotransposons collec...
متن کاملDo human transposable element small RNAs serve primarily as genome defenders or genome regulators?
It is currently thought that small RNA (sRNA) based repression mechanisms are primarily employed to mitigate the mutagenic threat posed by the activity of transposable elements (TEs). This can be achieved by the sRNA guided processing of TE transcripts via Dicer-dependent (e.g., siRNA) or Dicer-independent (e.g., piRNA) mechanisms. For example, potentially active human L1 elements are silenced ...
متن کاملGenome-wide discovery of G-quadruplex forming sequences and their functional relevance in plants
DNA, in addition to the canonical B-form, can acquire a variety of alternate structures, such as G-quadruplexes. These structures have been implicated in several cellular processes in animals. In this study, we identified different types of G-quadruplex forming sequences (GQSes) in 15 sequenced plants and analyzed their distribution in various genomic features, including gene body, coding, inte...
متن کاملPolymorphism and resolution of oncogene promoter quadruplex-forming sequences.
We report the separation of several quadruplex species formed by ten promoter sequences by Size Exclusion Chromatography (SEC). Modification at the 5' or 3' ends or in loop regions of quadruplex forming sequences has become the standard technique for dealing with quadruplex polymorphism. However, conformations produced employing this method or by other means of artificially shifting the equilib...
متن کاملQuantitative analysis and prediction of G-quadruplex forming sequences in double-stranded DNA
G-quadruplex (GQ) is a four-stranded DNA structure that can be formed in guanine-rich sequences. GQ structures have been proposed to regulate diverse biological processes including transcription, replication, translation and telomere maintenance. Recent studies have demonstrated the existence of GQ DNA in live mammalian cells and a significant number of potential GQ forming sequences in the hum...
