Structural and functional analysis of Utp24, an endonuclease for processing 18S ribosomal RNA. [PDF]
The precursor ribosomal RNA is processed by multiple steps of nucleolytic cleavage to generate mature rRNAs. Utp24 is a PIN domain endonuclease in the early 90S precursor of small ribosomal subunit and is proposed to cleave at sites A1 and A2 of pre-rRNA.

18S Ribosomal RNA Evaluation as Preanalytical Quality Control for Animal DNA. [PDF]
The 18S ribosomal RNA (rRNA) gene is present in all eukaryotic cells. In this study, we evaluated the use of this gene to verify the presence of PCR-amplifiable host (animal) DNA as an indicator of sufficient sample quality for quantitative real-time PCR (qPCR) analysis.

18S Ribosomal RNA and Tetrapod Phylogeny [PDF]
Previous phylogenetic analyses of tetrapod 18S ribosomal RNA (rRNA) sequences support the grouping of birds with mammals, whereas other molecular data, and morphological and paleontological data favor the grouping of birds with crocodiles. The 18S rRNA gene has consequently been considered odd, serving as "definitive evidence of different genes ...

Structure of 18 S Ribosomal RNA in Native 40 S Ribosomal Subunits [PDF]
We have analyzed the structure of 18 S rRNA in native 40 S subunits using chemical modification followed by primer extension. The native subunits were modified using the single-stranded specific reagents dimethyl sulfate and 1-cyclohexyl-3-(2-morpholinoethyl)carbodiimide metho-p-toluenesulfonate.

Selection of reference genes for expression analysis using quantitative real-time PCR in the pea aphid, Acyrthosiphon pisum (Harris) (Hemiptera, Aphidiae). [PDF]
To facilitate gene expression study and obtain accurate qRT-PCR analysis, normalization relative to stable expressed housekeeping genes is required. In this study, expression profiles of 11 candidate reference genes, including actin (Actin), elongation ...

The final step of 40S ribosomal subunit maturation is controlled by a dual key lock
Preventing premature interaction of pre-ribosomes with the translation apparatus is essential for translational accuracy. Hence, the final maturation step releasing functional 40S ribosomal subunits, namely processing of the 18S ribosomal RNA 3′ end, is ...

Basepairing with 18S ribosomal RNA in internal initiation of translation [PDF]
In concert with the translation initiation factors ‘trans‐acting’ factors function specifically during internal initiation on picornaviral mRNAs. Of these trans‐acting factors, two have been identified as the La‐protein and the polypyrimidine tract binding protein.
