Small nucleolar RNA snoR1 is a non-coding RNA (ncRNA) molecule which functions in the modification of other small nuclear RNAs (snRNAs). This type of modifiying RNA is usually located in the nucleolus of the eukaryotic cell which is a major site of snRNA biogenesis. It is known as a small nucleolar RNA (snoRNA) and also often referred to as a guide RNA. snoRNA snoR1 belongs to 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. Plant snoRNA snoR1 was identified in a screen of Arabidopsis thaliana.
Famous quotes containing the word small:
“Good marriages are built on respectful disagreement and back-and-forth cooperation. We learn to cue each other, fill in for each other, forgive each other’s fumbles, celebrate small victories. We revel in the realization that we’re working on something bigger than both of us, and that parenthood is not only incredibly challenging but also incredibly enriching.”
—Susan Lapinski (20th century)
