context_page_description: snoRNA Z199 is a non-coding RNA molecule which functions in the biogenesis of other small nuclear RNAs. This type of modifying RNA is located in the nucleolus of the eukaryotic cell which is a major site of snRNA biogenesis. It is known as a small nucleolar RNA and also often referred to as a guide RNA.
  snoRNA Z199 is a member of the C/D box class of snoRNAs which contain the conserved sequence motifs known as the C box and the D box. Most of the members of the box C/D family function in directing site-specific 2'-O-methylation of substrate RNAs.
  snoZ199 is predicted to be a methylation guide for sites on 18S and 25S ribosomal RNA. Oryza sativa snoZ199 is reported to be homologous to Arabidopsis thaliana snoR13.

  snoRNA Z199 is a member of the C/D box class of snoRNAs which contain the conserved sequence motifs known as the C box (UGAUGA) and the D box (CUGA). Most of the members of the box C/D family function in directing site-specific 2'-O-methylation of substrate RNAs.
  snoZ199 is predicted to be a methylation guide for sites on 18S and 25S ribosomal RNA (rRNA).  Oryza sativa snoZ199 is reported to be homologous to Arabidopsis thaliana snoR13.
