Predicted to enable 5'-3' exoribonuclease activity and m7G(5')pppN diphosphatase activity. Predicted to be involved in negative regulation of telomere maintenance via telomerase; nuclear-transcribed mRNA catabolic process; and regulation of telomerase RNA localization to Cajal body. Predicted to be located in cell junction; cytoplasmic ribonucleoprotein granule; and nucleoplasm. Predicted to be part of RISC complex. Predicted to be active in P-body. Orthologous to human DCP2 (decapping mRNA 2). [provided by Alliance of Genome Resources, Apr 2022]
