Predicted to enable 5'-3' exoribonuclease activity and m7G(5')pppN diphosphatase activity. Involved in mRNA catabolic process. 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. Is expressed in several structures, including genitourinary system; heart; liver; lung; and spleen. Orthologous to human DCP2 (decapping mRNA 2). [provided by Alliance of Genome Resources, Apr 2022]
