| PubMed Abstract | A significant portion of eukaryotic small ncRNA transcriptome is composed by small nucleolar RNAs. From archaeal to mammalian cells, these molecules act as guides in the site-specific pseudouridylation or methylation of target RNAs. We used a bioinformatics search program to detect Drosophila putative orthologues of U79, one out of ten snoRNAs produced by GAS5, a human ncRNA involved in apoptosis, susceptibility to cancer and autoimmune diseases. This search led to the definition of a list of U79-related fly snoRNAs whose genomic organization, evolution and expression strategy are discussed here. We report that an intriguing novel specimen, named Dm46E3, is transcribed as a longer, unspliced precursor from the reverse strand of eiger, a fly regulatory gene that plays a key role in cell differentiation, apoptosis and immune response. Expression of Dm46E3 was found significantly up-regulated in a mutant strain in which eiger transcription is greatly reduced, suggesting that these two sense-antisense genes may be mutually regulated. Relevant to its function, Dm46E3 concentrated specifically in the Cajal bodies, followed a dynamic spatial expression profile during embryogenesis and displayed a degenerate antisense element that enables it to target U1b, a developmentally regulated isoform of the U1 spliceosomal snRNA that is particularly abundant in embryos. | ||
