This type of modifying 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 U61 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.[1] U61 snoRNA was cloned from HeLa cells[2] and is predicted to guide the 2'O-ribose methylation of 18S ribosomal RNA (rRNA) residue U1442.[3] References1. ^{{Cite journal | last1 = Galardi | first1 = S.| last2 = Fatica | first2 = A.| last3 = Bachi | first3 = A.| last4 = Scaloni | first4 = A.| last5 = Presutti | first5 = C.| last6 = Bozzoni | first6 = I.| doi = 10.1128/MCB.22.19.6663-6668.2002 | title = Purified Box C/D snoRNPs Are Able to Reproduce Site-Specific 2'-O-Methylation of Target RNA in Vitro | journal = Molecular and Cellular Biology| volume = 22 | issue = 19 | pages = 6663–6668 | date=October 2002 | pmid = 12215523| pmc = 134041}} 2. ^{{Cite journal | last1 = Kiss-László | first1 = Zsuzsanna| last2 = Henry | first2 = Yves| last3 = Bachellerie | first3 = Jean-Pierre| last4 = Caizergues-Ferrer | first4 = Michèle| last5 = Kiss | first5 = Tamás| title = Site-specific ribose methylation of preribosomal RNA: a novel function for small nucleolar RNAs| doi = 10.1016/S0092-8674(00)81308-2 | journal = Cell| volume = 85 | issue = 7 | pages = 1077–1088 | date=June 1996 | pmid = 8674114| pmc = }} 3. ^{{Cite journal | last1 = Lestrade | first1 = Laurent | last2 = Weber | first2 = Michel J. | title = snoRNA-LBME-db, a comprehensive database of human H/ACA and C/D box snoRNAs | doi = 10.1093/nar/gkj002 | journal = Nucleic Acids Research | volume = 34 | issue = Supplement 1: Database Issue | pages = D158–D162 | year = 2006 | pmc = 1347365 | pmid = 16381836 | citeseerx=10.1.1.105.7552}} External links
