Small Nucleolar RNA SNORD100

Small Nucleolar RNA SNORD100 (also known as HBII-429) is a non-coding RNA (ncRNA) molecule which functions in the biogenesis (modification) of other small nuclear RNAs (snRNAs). This type of modifiying 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 (snoRNA) and also often referred to as a guide RNA.

SNORD100 belongs to the C/D box class of snoRNAs which contain the C (UGAUGA) and D (CUGA) box motifs. Most of the members of the box C/D family function in directing site-specific 2'-O-methylation of substrate RNAs [1] . SNORD100 is predicted to guide the 2'O-ribose methylation of 18S ribosomal RNA (rRNA) at residue G436 [3] .
