DCP1B May play a role in the degradation of mRNAs, both in normal mRNA turnover and in nonsense-mediated mRNA decay. May remove the 7-methyl guanine cap structure from mRNA molecules, yielding a 5'-phosphorylated mRNA fragment and 7m-GDP. Belongs to the DCP1 family. 2 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
