Secondary Accession Numbers
  • 14432
Name m7GpppN-mRNA hydrolase
Synonyms
  1. Nucleoside diphosphate-linked moiety X motif 20
  2. Nudix motif 20
  3. hDpc
  4. mRNA-decapping enzyme 2
Gene Name DCP2
Protein Type Unknown
Biological Properties
General Function Involved in RNA binding
Specific Function Necessary for the degradation of mRNAs, both in normal mRNA turnover and in nonsense-mediated mRNA decay. Plays a role in replication-dependent histone mRNA degradation. Removes the 7-methyl guanine cap structure from mRNA molecules, yielding a 5'-phosphorylated mRNA fragment and 7m-GDP. Has higher activity towards mRNAs that lack a poly(A) tail. Has no activity towards a cap structure lacking a RNA moiety.
Pathways
  • RNA degradation
