Large Stokes shift fluorescence activation in an RNA aptamer by intermolecular proton transfer to guanine.
(NATURE RESEARCH, 2021-06-10)
Fluorogenic RNA aptamers are synthetic functional RNAs that specifically bind and activate conditional fluorophores. The Chili RNA aptamer mimics large Stokes shift fluorescent proteins and exhibits high affinity for ...
Structural basis of intron selection by U2 snRNP in the presence of covalent inhibitors
(Springer Science and Business Media LLC, 2021-07-23)
<jats:title>Abstract</jats:title><jats:p>Intron selection during the formation of prespliceosomes is a critical event in pre-mRNA splicing. Chemical modulation of intron selection has emerged as a route for cancer therapy. ...
An integrated model for termination of RNA polymerase III transcription.
(American Association for the Advancement of Science (AAAS), 2022-07-15)
RNA polymerase III (RNAPIII) synthesizes essential and abundant noncoding RNAs such as transfer RNAs. Controlling RNAPIII span of activity by accurate and efficient termination is a challenging necessity to ensure robust ...
Structural basis of catalytic activation in human splicing.
(NATURE PORTFOLIO, 2023-05-25)
Pre-mRNA splicing follows a pathway driven by ATP-dependent RNA helicases. A crucial event of the splicing pathway is the catalytic activation, which takes place at the transition between the activated Bact and the ...
Alternative catalytic residues in the active site of Esco acetyltransferases.
(NATURE PORTFOLIO, 2020-06-17)
Cohesin is a protein complex whose core subunits, Smc1, Smc3, Scc1, and SA1/SA2 form a ring-like structure encircling the DNA. Cohesins play a key role in the expression, repair, and segregation of eukaryotic genomes. ...
