Clan: SNORA21 (CL00031)

Summary

SNORA21 clan

The SNORA21 clan contains the RNA families SNORA21, snR10 and S_pombe_snR10. 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: SNORA21 and snR10 [2].

This clan contains 3 families and the total number of sequence regions in the clan is 228.
