Predicted to enable endoribonuclease activity and mRNA binding activity. Involved in 3'-UTR-mediated mRNA destabilization. Acts upstream of or within mRNA catabolic process and negative regulation of T cell proliferation. Predicted to be located in P-body and nucleoplasm. Predicted to be active in cytoplasmic ribonucleoprotein granule and nucleus. Orthologous to human ZC3H12D (zinc finger CCCH-type containing 12D). [provided by Alliance of Genome Resources, Apr 2022]
