Small nucleolar RNA SNORA73

In molecular biology, the small nucleolar RNA SNORA73 belongs to the H/ACA class of small nucleolar RNAs (snoRNAs). Vertebrate U17 is intron-encoded and ranges in length from 200-230 nucleotides, longer than most snoRNAs. It is one of the most abundant snoRNAs in human cells and is essential for the cleavage of pre-rRNA within the 5' external transcribed spacer (ETS). This cleavage leads to the formation of 18S rRNA. Regions of the U17 RNA are complementary to rRNA and act as guides for RNA/RNA interactions, although these regions do not seem to be well conserved between organisms.

Small nucleolar RNA SNORA74

In molecular biology, Small nucleolar RNA SNORA74 (U19) belongs to the H/ACA class of snoRNAs. snoRNAs bind a number of proteins to form snoRNP complexes. This class is thought to guide the sites of modification of uridines to pseudouridines by forming direct base pairing interactions with substrate RNAs. Targets may include ribosomal and spliceosomal RNAs but the exact functions of many snoRNAs, including U19, are not confirmed. Co-precipitation of U19 snoRNA with RNase MRP RNA suggests that U19 may be involved in pre-rRNA processing.
