20. ColabFold-AlphaFold2 prediction of ORF-A supports (pLDDT confidence up to 93.5 for several models) that these proteins take on the classic right-handed palm domain architecture, with highest structural similarity to negarnavirus RdRps (Influenza A, Z...
Transposable elements (TEs), also called mobile elements, are DNA fragments that may move about inside a host genome and typically make new copies of themselves while they do so. They are present across all forms of life, accounting for 50% of the mammalian genome [1,2,3]. TEs are prese...
DNA can determine where and when genes are expressed, but the full set of sequence determinants that control gene expression is unknown. Here, we measured the transcriptional activity of DNA sequences that represent an ~100 times larger sequence space th

DNA can determine where and when genes are expressed, but the full set of sequence determinants that control gene expression is unknown. Here, we measured the transcriptional activity of DNA sequences that represent an ~100 times larger sequence space than the human genome using massively parallel...
Enhancers are operated by the combinatorial action of TFs that recognize specific DNA motifs clustered within the enhancer elements. In order to bring the recruited regulatory proteins in the vicinity of a target gene, enhancers are thought to engage in long-range chromatin interactions (Ong & ...
Hydrogen is also a vital component of compounds such as proteins, carbohydrates, and lipids. Nitrogen, hydrogen, and oxygen all contribute to DNA structure Water molecules consist of hydrogen and oxygen A hydrogen bond Macrominerals Macrominerals are minerals that are needed in large amounts by ...
of MGEs in new hosts. Stable appropriation of the foreign DNA depends on a number of host factors among which are the Nucleoid-Associated Proteins (NAPs). These small, basic, highly abundant proteins bind and bend DNA, altering its topology and folding, thereby affecting all known essentialDNA...
Class 4 proteins, called Mini-III, are the smallest members of the RNase III superfamily. They consist solely of a catalytic domain and act as homodimers. Determination of the crystal structure of a canonical RNase III in complex with dsRNA revealed patterns of interactions between the enzyme ...
Many of these elements consist of RNA structural motifs and/or internal sequences that recruit RNA binding proteins. To date, it is still unclear how prevalent these RNA elements are or their precise nature and characteristics. Further study into their evolutionary implications in the virus-host ...
