Predicted to enable RNA 7-methylguanosine cap binding activity; identical protein binding activity; and m7G(5')pppN diphosphatase activity. Predicted to be involved in cellular response to menadione; mRNA metabolic process; and negative regulation of programmed cell death. Predicted to act upstream of or within RNA splicing and mRNA processing. Predicted to be located in cytosol; mitochondrion; and nucleoplasm. Predicted to be active in P-body and nucleus. Is expressed in several structures, including adrenal gland; alimentary system; genitourinary system; nervous system; and sensory organ. Orthologous to human DCPS (decapping enzyme, scavenger).
