Comments:

Bud23 is the methyltransferase required for N7 methylation of guanosine 1531 on the 18S rRNA. Together with DIMT1 (m6,6A s:1735, 1736)those modifications are involved in the inheritance of non-genetic information by altering ribosome heterogeneity rather than through eliciting a general defect in ribosome biogenesis.
