Enables polynucleotide 5'-phosphatase activity. Involved in polynucleotide 5' dephosphorylation and positive regulation of gene expression. Located in nucleus. Expressed in tail. Is an ortholog of human RNGTT (RNA guanylyltransferase and 5'-phosphatase).
Predicted to enable metal ion binding activity. Involved in nematode larval development; positive regulation of growth rate; and programmed cell death.
