Abstract :
Homo sapiens C/D box snoRNA HBII-99. This snoRNA is the human orthologue of the mouse MBII-99 described by Hüttenhofer et al. (2001). It is predicted to guide the 2'O-ribose methylation of 28S rRNA G3878.HBII-99 (SNORD12), U106 (SNORD12C) and the highly related copy SNORD12B (GenBank AM413026, Yang et al., 2006) share the same host gene (C20orf199), and have probably the same RNA target.
