LGP2 is a RIG-I-like receptor (RLR) known to bind and recognize the intermediate double-stranded RNA (dsRNA) during virus infection and to induce type-I interferon (IFN)-related antiviral innate immune responses.

Crystal structure of the 14-subunit RNA polymerase I
Protein biosynthesis depends on the availability of ribosomes, which in turn relies on ribosomal RNA production. In eukaryotes, this process is carried out by RNA polymerase I (Pol I), a 14-subunit enzyme, the activity of which is a major determinant of ...

Interchangeable RNA polymerase I and II enhancers. [PDF]
The RNA polymerase I (pol I) enhancer of Saccharomyces cerevisiae contains at least three elements commonly associated with RNA polymerase II (pol II) enhancers, binding sites for the transcriptional activators general regulatory factor 2 and autonomously replicating sequence-binding factor I, and a thymidine-rich element.

Residue profile in predivergence sequences as a guide to the origin of DNA replication [PDF]
DNA dependent RNA polymerase core subunits abb' conserved residues at frequencies most closely matched with codons at stage 10.4-11.1 in code evolution. An excess of acidic residues (stage 2 additions) lowered this estimate, but not by more than 2.3 stages.

How the Avidity of Polymerase Binding to the -35/-10 Promoter Sites Affects Gene Expression [PDF]
Although the key promoter elements necessary to drive transcription in Escherichia coli have long been understood, we still cannot predict the behavior of arbitrary novel promoters, hampering our ability to characterize the myriad of sequenced regulatory architectures as well as to design novel synthetic circuits.

Efficient termination of transcription by RNA polymerase I requires the 5 ' exonuclease Rat1 in yeast [PDF]
During transcription termination by RNA polymerase II on protein-coding genes, the nuclear 5′ exonuclease Rat1/Xrn2 degrades the nascent transcript downstream from the polyadenylation site and “torpedoes” the polymerase.

Bayesian inference of polymerase dynamics over the exclusion process [PDF]
Transcription is a complex phenomenon that permits the conversion of genetic information into phenotype by means of an enzyme called RNA polymerase, which erratically moves along and scans the DNA template. We perform Bayesian inference over a paradigmatic mechanistic model of non-equilibrium statistical physics, i.e., the asymmetric exclusion ...

All cellular RNA polymerases are influenced by protein factors that stimulate RNA polymerase-catalyzed cleavage of the nascent RNA. Despite divergence in amino acid sequence, these so-called "cleavage factors" appear to share a common mechanism of action.

Transcription-translation machinery -- an autocatalytic network coupling all cellular cycles and generating a plethora of growth laws [PDF]
Recently discovered simple quantitative relations, known as bacterial growth laws, hint on the existence of simple underlying principles at the heart of bacterial growth. In this work, we provide a unifying picture on how these known relations, as well as new relations that we derive, stems from a universal autocatalytic network common to all bacteria,
