WebbSpinal muscular atrophy is caused by deletions or mutations in the SMN1 gene that result in reduced expression of the SMN protein. The SMN protein is an essential molecular chaperone that is required for the biogenesis of multiple ribonucleoprotein (RNP) complexes including spliceosomal small nuclear RNPs (snRNPs). WebbThe primary role of snoRNAs is to direct the posttranscriptional modification of target RNAs, including ribosomal RNAs, small nuclear RNAs, transfer RNAs, and probably other cellular RNAs, which has been well described. 18 In recent years, in addition to the above-mentioned classical role of snoRNAs, emerging studies have exposed their potential …

Webb24 apr. 1998 · Small nucleolar ribonucleoproteins (snoRNPs) have been shown to act as “guide RNAs” during rRNA maturation ( 38 ), targeting sites of 2′- O -methyl ribose and pseudouridine formation [D box and ACA snoRNPs, respectively ( 39 )] and directing nucleolytic cleavage of the rRNA precursor [U3, U8, U14, and U22 snoRNPs ( 38 )]. Webb10 juli 2007 · Uridine-rich small nuclear ribonucleoproteins (U snRNPs) are involved in key steps of pre-mRNA processing in the nucleus of eukaryotic cells. U snRNPs are enriched in the nucleus in discrete organelles that include speckles, Cajal bodies, and histone locus bodies. However, most U snRNPs are assembled in the cytoplasm, not in the nucleus.
