Predicted to enable identical protein binding activity; mRNA binding activity; and phosphodiesterase decapping endonuclease activity. Predicted to be involved in P-body assembly and deadenylation-independent decapping of nuclear-transcribed mRNA. Predicted to be located in cytoplasmic ribonucleoprotein granule. Predicted to be active in P-body. Is expressed in cerebellum; embryo; hippocampus; retina inner nuclear layer; and retina outer nuclear layer. Human ortholog(s) of this gene implicated in autosomal recessive non-syndromic intellectual disability. Orthologous to human EDC3 (enhancer of mRNA decapping 3).
