a All the box H/ACA snoRNAs were numbered according to the order of identification. b Len, cDNA length of the snoRNA. c Chr, chromosomal location of snoRNA gene. d Exp, expression situation. C, N, R, snoRNA was identified by cDNA library, northern blotting analysis, and reverse transcription analysis, respectively. e Gp, guide position. g IR, Intergenic region. The data for S. p snoRNAs were cited from Luo (2004) [38]. "Undet" indicates that the snoRNA has not been identified in the human genome although the corresponding modification site was detected. Abbreviation: S. p, S. pombe; S. c, S. cerevisia; A. t, A. thaliana; H. s, H. sapiens.
