U8 snoRNA-decapping enzyme (Nudt16)

RNA-binding and decapping enzyme that catalyzes the cleavage of the cap structure of snoRNAs and mRNAs in a metal- dependent manner. Part of the U8 snoRNP complex that's required for the accumulation of mature 5.

8S and 28S rRNA. Has diphosphatase activity and eliminates m7G and/or m227G caps from U8 snoRNA and leaves a 5'monophosphate on the RNA.
