The pervasive transcription hypothesis states that all DNA of an organism is associated with at least one transcript and it has been strenghtened by the acquisison of massive transcriptomic data. An important question that arises in this context is the functionality and regulation of theses transcripts in a global gene regulatory network, specially of transcripts located antisense to anno…
Systems approaches have been developed in the post-genomic era to have a global understanding of the cell. In this framework, the use of computational, mathematical and statistical tools, together with new technologies in biology allow the development of global models with predictive power. These global models usually take into account mRNA and protein levels. However, there is an increas…
Circular RNAs (circRNAs) are closed RNA molecules with their 5' and 3' ends covalently ligated. They were first discovered in viruses and viroids and then in eukaryotes. CircRNAs are progressively being understood as functional molecules and not as mere splicing by-products: their functions range from acting as genetic regulators to being translated. Next generation sequencing experiment…
Halobacterium salinarum NRC-1 is an extremophile halophile, and as an archaeon organism has characteristics shared by eukaryotes and bacteria. Since it is easy to manipulate H. salinarum in the laboratory, it has become a model for genetic studies, most of which characterized its genome as highly unstable due to the high frequency of spontaneous mutations. Our research group study differe…
Insertion sequences (IS) are ubiquitous mobile genetic elements in prokaryotes that promote great impact on host genomes. They can provide fitness to organisms by enhancing the genetic diversity and also by modulating gene expression. On the other hand, mobilization events that damage the host are also common, specially when an essential gene is disrupted and compromises the organism viab…
A plethora of circular RNAs (circRNAs) has been recently reported in organisms from all domains of life, indicating its importance in gene regulatory networks. In the Archaea domain, Halobacterium salinarum has been established as a model organism since it is easy to grow in the laboratory and amenable to genetic manipulations. These properties also allowed the acquisition of abundant dat…

Our main project has the purpose of identifying the components of insertion sequence regulation in Halobacterium salinarum, primarily those acting on the post-transcriptional level. We successfully identified several transposase-encoding mRNAs binding to the LSm protein, which can repress or induce translation by changing the way ribosome couple with transcripts. We evaluated insertion se…
