POP1

Ribonucleases P/MRP protein subunit POP1

1024 amino acids

Component of ribonuclease P, a ribonucleoprotein complex that generates mature tRNA molecules by cleaving their 5'-ends (PubMed:8918471, PubMed:30454648). Also a component of the MRP ribonuclease complex, which cleaves pre-rRNA sequences (PubMed:28115465).

pop1

WD repeat-containing protein pop1

775 amino acids

Involved in maintenance of ploidy through proteasome dependent degradation of CDK inhibitor rum1 and S-phase initiator cdc18. Functions as a recognition factor for rum1 and cdc18, which are subsequently ubiquitinated and targeted to the 26S proteasome for degradation. Together with pop2, required for cig2 instability during G2 and M phase and cig2 degradation in exponentially growing cells. Regulates cell-cycle progression under starvation through the rum1 protein.
