Predicted to enable several functions, including histone deacetylase binding activity; mRNA 3'-UTR AU-rich region binding activity; and protein homodimerization activity. Predicted to contribute to RNA binding activity. Predicted to be involved in several processes, including positive regulation of cell differentiation; protein-containing complex assembly; and regulation of mRNA metabolic process. Predicted to be located in centriolar satellite; cytoplasm; and paraspeckles. Predicted to be part of mRNA cleavage and polyadenylation specificity factor complex. Orthologous to human NUDT21 (nudix hydrolase 21). [provided by Alliance of Genome Resources, Apr 2022]
