Clan: SNORA36 (CL00035)


SNORA36 clan

The SNORA36 clan contains the RNA families SNORA36, snR36, snR44 and S_pombe_snR36. 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: SNORA36 and snR36, SNORA36 and snR44 [2].

This clan contains 4 families and the total number of sequence regions in the clan is 831.
