a decapping enzyme. Plays a role in general and regulated mRNA decay. Apparently plays a role in the nonsense-mediated decay pathway that rids cells of mRNAs containing premature termination codons. May function as a transactivator of SMAD4 that participates in TGF-beta signaling. Note: This description may include information from UniProtKB.
Protein type: EC 3.-.-.-; Hydrolase; RNA processing; Transcription, coactivator/corepressor
