Homo sapiens ACA67B H/ACA box snoRNA. This snoRNA is the most likely parental copy of snoRT ACA67 (Weber,2006; Luo and Li, 2007). A second primate-specific Type 1 ACA67B snoRT resides in the JTV1 gene (chr7:6,023,034-6,023,168). A third one (extragenic, chr16:30,338,447-30,338,581) is embedded in a complex array of Alu elements. ACA42 might be an old ACA67B snoRT. A rodent-specific snoRT resides in the RPL6 gene, and a cow-specific one in the EIF2A gene.
In opossum, platypus, lizard and Xenopus tropicalis, the closest paralog of ACA67B (ACA67E) resides in the SSR4 gene. |
