CC -!- FUNCTION: Decapping metalloenzyme that catalyzes the cleavage of the
CC cap structure on mRNAs (PubMed:12417715, PubMed:12218187,
CC PubMed:12923261, PubMed:21070968, PubMed:28002401, PubMed:31875550).
CC Removes the 7-methyl guanine cap structure from mRNA molecules,
CC yielding a 5'-phosphorylated mRNA fragment and 7m-GDP (PubMed:12486012,
CC PubMed:12923261, PubMed:21070968, PubMed:28002401, PubMed:31875550).
CC Necessary for the degradation of mRNAs, both in normal mRNA turnover
CC and in nonsense-mediated mRNA decay (PubMed:14527413). Plays a role in
CC replication-dependent histone mRNA degradation (PubMed:18172165). Has
CC higher activity towards mRNAs that lack a poly(A) tail
CC (PubMed:21070968). Has no activity towards a cap structure lacking an
CC RNA moiety (PubMed:21070968). The presence of a N(6)-methyladenosine
CC methylation at the second transcribed position of mRNAs (N(6),2'-O-
CC dimethyladenosine cap; m6A(m)) provides resistance to DCP2-mediated
CC decapping (PubMed:28002401). Blocks autophagy in nutrient-rich
CC conditions by repressing the expression of ATG-related genes through
CC degradation of their transcripts (PubMed:26098573).
