| - | = | + | [https://www.uniprot.org/uniprot/DXO_ASHGO DXO_ASHGO] Decapping enzyme for NAD-capped RNAs: specifically hydrolyzes the nicotinamide adenine dinucleotide (NAD) cap from a subset of RNAs by removing the entire NAD moiety from the 5'-end of an NAD-capped RNA (By similarity). The NAD-cap is present at the 5'-end of some RNAs and snoRNAs (By similarity). In contrast to the canonical 5'-end N7 methylguanosine (m7G) cap, the NAD cap promotes mRNA decay (By similarity). Also acts as a non-canonical decapping enzyme that removes the entire cap structure of m7G capped or incompletely capped RNAs and mediates their subsequent degradation (PubMed:26101253). Specifically degrades pre-mRNAs with a defective m7G cap and is part of a pre-mRNA capping quality control (PubMed:26101253). Has decapping activity toward incomplete 5'-end m7G cap mRNAs such as unmethylated 5'-end-capped RNA (cap0), while it has no activity toward 2'-O-ribose methylated m7G cap (cap1) (By similarity). Also has 5'-3' exonuclease activity (PubMed:26101253). Also possesses RNA 5'-pyrophosphohydrolase activity by hydrolyzing the 5'-end triphosphate to release pyrophosphates (PubMed:26101253).[UniProtKB:O13836][UniProtKB:O70348][UniProtKB:Q06349]<ref>PMID:26101253</ref> |
