Homo sapiens C/D box snoRNA U62B. This snoRNA was cloned from RNAs immunoprecipitated with an anti-fibrillarin antibody (Tycowski et al. 1996). It is predicted to guide the 2'O-ribose methylation of 18S rRNA A590. U62B and a second exact copy, U62A, reside in the same host gene (KIAA0515 hypothetical protein).
