  snoRNA (na obrázku) je důležitou složkou snoRNP komplexů snoRNP je zkratka pro skupinu ribonukleoproteinů vzniklá z anglického spojení small nucleolar ribonucleoprotein, tedy malý jadérkový ribonukleoprotein. Jedná se o komplexy RNA a bílkovin, vyskytující se v jadérku. Zmíněná RNA se konkrétně označuje jako snoRNA.[1] SnoRNA komplexy se účastní zřejmě zejména…

The 5′ stem-loop of the U4 snRNA and the box C/D motif of the box C/D snoRNAs can both be folded into a similar stem-internal loop-stem structure that binds the 15.5K protein. The homologous proteins NOP56 and NOP58 and 61K (hPrp31) associate with the box C/D snoRNPs and the U4/U6…

The synthesis of ribosomes involves many small nucleolar ribonucleoprotein particles (snoRNPs) as trans-acting factors. Yeast strains lacking the snoRNA, snR10, are viable but are impaired in growth and delayed in the early pre-rRNA cleavages at sites A0, A1, and A2, which lead to the synthesis of 18S rRNA. The same…

Abstract: Background Box C/D snoRNPs are responsible for rRNA methylation and processing, and are formed by snoRNAs and four conserved proteins, Nop1, Nop56, Nop58 and Snu13. The snoRNP assembly is a stepwise process, involving other protein complexes, among which the R2TP and Hsp90 chaperone. Nop17, also known as Pih1, has…

Chemical modification of biomolecules is an impressive way of nature to expand their functional diversity. Like DNA and proteins, RNA molecules also undergo a variety of chemical modifications that allow them to enrich their topological potential and perform a variety of functions that go beyond their capacity to encode proteins…
