Protein attributes

Sequence length	617 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	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 By similarity.
Subunit structure	Binds DCP1A. Part of a complex containing enzymes involved in mRNA decay, including DCP2, LSM1, LSM3 and CNOT6.
Subcellular location	Cytoplasm. Nucleus By similarity Ref.5.
Sequence similarities	Belongs to the DCP1 family.
Sequence caution	The sequence AAH15368.2 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened.
