Predicted to enable ribonuclease P RNA binding activity. Predicted to be involved in rRNA processing. Predicted to act upstream of or within tRNA 5'-leader removal. Predicted to be located in nucleolus. Predicted to be part of ribonuclease MRP complex and ribonuclease P complex. Orthologous to human POP4 (POP4 homolog, ribonuclease P/MRP subunit).
