Summary
SNORA52 clan
The SNORA52 clan contains the RNA families SNORA66, snoR98, SNORA52, SNORA18, snoR80, snR49, snR5 and S_pombe_snR5. Homology between these families has been established in the published literature [1]. Researchers at the human snoRNA database (snoRNABase) have established that the following human and S. cerevisiae snoRNAs target modifications on orthologous positions of the ribosome: U66 and snR49, SNORA52 and snR5 [2]. Researchers at the plant snoRNA database have established that the following arabadopsis, human and S. cerevisiae snoRNAs target modifications on orthologous positions of the ribosome: snoR80 and SnR5, snoR98 and SnR5 [3].
This clan contains 8 families and the total number of sequence regions in the clan is 4,508.
