CC -!- FUNCTION: Decapping enzyme for NAD-capped RNAs: specifically hydrolyzes
CC the nicotinamide adenine dinucleotide (NAD) cap from a subset of RNAs
CC by removing the entire NAD moiety from the 5'-end of an NAD-capped RNA
CC (By similarity). The NAD-cap is present at the 5'-end of some RNAs and
CC snoRNAs. In contrast to the canonical 5'-end N7 methylguanosine (m7G)
CC cap, the NAD cap promotes mRNA decay (By similarity). Also acts as a
CC non-canonical decapping enzyme that removes the entire cap structure of
CC m7G capped or incompletely capped RNAs (By similarity). Has decapping
CC activity toward incomplete 5'-end m7G cap mRNAs such as unmethylated
CC 5'-end-capped RNA (cap0), while it has no activity toward 2'-O-ribose
CC methylated m7G cap (cap1) (By similarity).
