Insights into the Evolution of small nucleolar RNAs
Over the last decades, the formerly irrevocable believe that proteins are the only key-factors in the complex regulatory machinery of a cell was crushed by a plethora of findings in all major eukaryotic lineages. These suggested a rugged landscape in the eukaryotic genome consisting of sequential, overlapping, or even bi-directional transcripts and myriads of regulatory elements. The vast part ...
متن کاملRibosomal RNA: Small nucleolar RNAs make their mark
Small nucleolar RNAs direct the location of certain methylations in ribosomal RNA by direct base pairing; although evolutionarily conserved, the physiological significance of these modifications remains unclear.
متن کاملEvolution of small nucleolar RNAs in nematodes
In contrast to mRNAs, which are templates for translating proteins, non-protein coding (npc) RNAs (also known as 'non-coding' RNA, ncRNA), exhibit various functions in different compartments and developmental stages of the cell. Small nucleolar RNAs (snoRNAs), one of the largest classes of npcRNAs, guide post-transcriptional modifications of other RNAs that are crucial for appropriate RNA foldi...
متن کاملHomologs of small nucleolar RNAs in Archaea.
In eukaryotes, dozens of posttranscriptional modifications are directed to specific nucleotides in ribosomal RNAs (rRNAs) by small nucleolar RNAs (snoRNAs). We identified homologs of snoRNA genes in both branches of the Archaea. Eighteen small sno-like RNAs (sRNAs) were cloned from the archaeon Sulfolobus acidocaldarius by coimmunoprecipitation with archaeal fibrillarin and NOP56, the homologs ...
متن کاملNucleolar localization signals of box H/ACA small nucleolar RNAs.
The two major families of small nucleolar RNAs (snoRNAs), Box C/D and Box H/ACA, are generated in the nucleoplasm and transported to the nucleolus where they function in rRNA processing and modification. We have investigated the sequences involved in the intranuclear transport of Box H/ACA snoRNAs by assaying the localization of injected fluorescent RNAs in Xenopus oocyte nuclear spreads. Our a...
