Small nucleolar RNA Z242

Small nucleolar RNA Z242 is a non-coding RNA (ncRNA) molecule which function in the biogenesis of other small nuclear RNAs (snRNAs). This small nucleolar RNA (snoRNA) is a modifiying RNA and usually located in the nucleolus of the eukaryotic cell which is a major site of snRNA biogenesis.

Most of the members of the box C/D family function in directing site-specific 2'-O-methylation of substrate RNAs [cite journal | last = Galardi | first = S | coauthors = Fatica A, Bachi A, Scaloni A, Presutti C, Bozzoni I | year = 2002 | title = Purified box C/D snoRNPs are able to reproduce site-specific 2'-O-methylation of target RNA in vitro | journal = Mol Cell Biol | volume = 22 | pages = 6663–6668 | pmid = 12215523 | doi = 10.1128/MCB.22.19.6663-6668.2002] .
