This entry represents a conserved region approximately 150 residues long located towards the N-terminus of the POP1 subunit that is common to both the RNase MRP and RNase P ribonucleoproteins (EC:3.1.26.5) [1]. These RNA-containing enzymes generate mature tRNA molecules by cleaving their 5' ends. This is a short N-terminal domain consisting of a small helical core and a long alpha-helix [2], which is enriched with positively charged residues involved in pre-tRNA substrate recognition [2].
