Conservation of Archaeal C/D Box sRNA-Guided RNA Modifications

Ruth Breuer, Jose-Vicente Gomes-Filho, Lennart Randau
2021 Frontiers in Microbiology  
Each C/D box sRNA contains two guide sequences that can act in coordination to bridge rRNA sequences. Here, we will review the landscape of archaeal C/D box sRNA genes and their target sites.  ...  In archaea, these modification sites are determined by variable sets of C/D box sRNAs that guide the activity of the rRNA 2'-O-methyltransferase fibrillarin.  ...  Additionally, it was revealed that many snoRNAs are processed into shorter forms such as miRNA (called sno-miRNA) and efficiently exert gene regulatory functions (Brameier et al., 2011) .  ...
