Arginine methylation in subunits of mammalian pre-mRNA cleavage factor I [PDF]

open access: yes, 2010
Mammalian cleavage factor I (CF Im) is composed of two polypeptides of 25 kDa and either a 59 or 68 kDa subunit (CF Im25, CF Im59, CF Im68). It is part of the cleavage and polyadenylation complex responsible for processing the 39 ends of messenger RNA ...

Identification of the Amide II Band in the cis-Amide 1-Methyluracil, in Poly(U), and in Poly(A)·Poly(U)

open access: yesJournal of Biological Chemistry, 1973
The amide II band, extensively studied in secondary trans-amides but generally reported to be absent in the infrared spectra of cis-amides, has been identified at 1417 cm-1 in the cyclic cis-amide 1-methyluracil. Specific isotopic substitution (2H, 18O, 15N) provides unambiguous evidence that the mode is an N—H bending vibration extensively coupled to ...

Impact of speciation on the tellurium electrochemistry in choline chloride-based deep eutectic solvents

open access: yesElectrochemistry Communications, 2022
The electrochemistry of tellurium in two different deep eutectic solvents, choline chloride - urea (ChCl-U) and choline chloride - oxalic acid (ChCl-Ox) was studied on glassy carbon (GC) and polycrystalline (Au(poly)) gold electrodes by cyclic and ...

The RRM domain of poly(A)-specific ribonuclease has a noncanonical binding site for mRNA cap analog recognition

open access: yes, 2008
The degradation of the poly(A) tail is crucial for posttranscriptional gene regulation and for quality control of mRNA. Poly(A)-specific ribonuclease (PARN) is one of the major mammalian 3’ specific exo-ribonucleases involved in the degradation of the ...
