Homo sapiens C/D box snoRNA snR39B. This snoRNA is the human orthologue of mouse snR39B described by Hui Zhou and Liang-Hu Qu (GeneBank AJ010680). It is predicted to guide the 2'O-ribose methylation of 28S rRNA G1509. It share the same host gene with the H/ACA box snoRNAs E3 and ACA4 (EIF4A2). It shares the same host gene with the H/ACA box snoRNAs E3, HBI-61 and ACA4 (EIF4A2).
