Predicted to enable several functions, including DNA polymerase binding activity; endoribonuclease activity; and nucleic acid binding activity. Predicted to be involved in negative regulation of telomere capping and nuclear-transcribed mRNA catabolic process, nonsense-mediated decay. Predicted to be located in cytosol and nucleolus. Predicted to be part of exon-exon junction complex and telomerase holoenzyme complex. Orthologous to human SMG6 (SMG6 nonsense mediated mRNA decay factor).
