POP1 homolog, ribonuclease P/MRP subunit is a human gene encoded by the symbol, POP1. It may also be known as: Ribonucleases P/MRP protein subunit POP1; hPOP1; processing of precursors 1; processing of precursor 1, ribonuclease P/MRP subunit (S. cerevisiae). The encoded protein is an enzyme with an amino acid length of 1024 and a mass of 114.7 kDa. Other isoforms may exist. Homologs of this gene exist in other organisms, including: Zebrafish, Chicken.
