Protein attributes

Sequence length	618 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
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.
Sequence similarities	Belongs to the DCP1 family.
