The SNORA2 clan contains the RNA families SNORA16, SNORA2, snopsi28S-3327, snR189, snR46 and S_pombe_snR46. Homology between these families has been established in the published literature . 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: SNORA2 and snR189, SNORA16 and snR46 .
This clan contains 6 families and the total number of sequence regions in the clan is 1,883.
