Recombinant human RPP14 (Ribonuclease P protein subunit p14) is a crucial component of the RNase P complex, a ribonucleoprotein enzyme responsible for processing precursor transfer RNA (tRNA) by catalyzing the cleavage of 5' leader sequences. RPP14. encoded by the RPP14 gene, is a nuclear protein that contributes to the structural integrity and catalytic activity of RNase P, which is essential for tRNA maturation and thus global protein synthesis.
As a recombinant protein, RPP14 is typically expressed in vitro using bacterial or eukaryotic expression systems (e.g., E. coli, mammalian cell lines) to ensure proper folding and post-translational modifications. Studies on RPP14 focus on its role in RNA metabolism, interactions with other RNase P subunits (e.g., RPP25. RPP20), and potential links to human diseases. Dysregulation of RNase P components has been implicated in developmental disorders, cancer, and mitochondrial dysfunction. Recombinant RPP14 serves as a valuable tool for biochemical assays, structural studies (e.g., X-ray crystallography), and functional analyses to unravel RNA-protein interaction mechanisms. Its applications extend to biomedical research, including investigations into tRNA processing defects and therapeutic targeting of RNase P-related pathologies.
