Summary
PRORP (protein only RNase P catalytic subunit, HGNC:19958) is a protein-coding gene on chromosome 14q13.2, encoding Mitochondrial ribonuclease P catalytic subunit (O15091). Catalytic ribonuclease component of mitochondrial ribonuclease P, a complex composed of TRMT10C/MRPP1, HSD17B10/MRPP2 and PRORP/MRPP3, which cleaves tRNA molecules in their 5’-ends. It is a selective cancer dependency (DepMap: 42.9% of cell lines).
Enables ribonuclease P activity. Involved in mitochondrial tRNA 5’-end processing. Located in mitochondrion and nucleoplasm. Part of mitochondrial ribonuclease P complex. Implicated in combined oxidative phosphorylation deficiency 54.

- Haplotypes in KIAA0391 and PSMA6 genes is a genetic link for myocardial infarction and coronary artery disease. (PMID:19624571)
- Inhibition of mitochondrial RNase P by beta-amyloid is an unspecific effect and is not mediated by beta-amyloid interaction with SDR5C1. (PMID:23755257)
- using a genome-wide association study, found that posttranscriptional modification of functionally important sites in mitochondrial transfer RNAs (tRNAs) is under strong genetic control, largely driven by a missense mutation in MRPP3 (PMID:24763589)
- This study presents the crystal structure of human MRPP3, which features a remarkably distorted and hence non-productive active site that authors propose will switch to a fully productive state only upon association with MRPP1, MRPP2 and pre-tRNA substrate. (PMID:25953853)
- This study proposes low-resolution models of the MRPP1-MRPP2 and MRPP1-MRPP2-MRPP3 complexes that suggest the overall architecture, stoichiometry, and orientation of subunits and tRNA substrates. (PMID:29880640)
- Structural basis of RNA processing by human mitochondrial RNase P. (PMID:34489609)
- Bi-allelic variants in the mitochondrial RNase P subunit PRORP cause mitochondrial tRNA processing defects and pleiotropic multisystem presentations. (PMID:34715011)
- Novel homozygous variants in PRORP expand the genotypic spectrum of combined oxidative phosphorylation deficiency 54. (PMID:37558808)

Function. Catalytic ribonuclease component of mitochondrial ribonuclease P, a complex composed of TRMT10C/MRPP1, HSD17B10/MRPP2 and PRORP/MRPP3, which cleaves tRNA molecules in their 5’-ends. The presence of TRMT10C/MRPP1, HSD17B10/MRPP2 is required to catalyze tRNA molecules in their 5’-ends.
Subunit / interactions. Catalytic component of mitochondrial ribonuclease P, a complex composed of TRMT10C/MRPP1, HSD17B10/MRPP2 and PRORP/MRPP3.
Subcellular location. Mitochondrion.
Post-translational modifications. Degraded by LONP1 following mitochondrial unfolded protein response, probably leading to inhibit translation in mitochondrion.
Disease relevance. Combined oxidative phosphorylation deficiency 54 (COXPD54) [MIM:619737] An autosomal recessive, multisystem disorder with highly variable manifestations resulting from defective mitochondrial transcription and translation. Clinical features include early-onset sensorineural hearing loss, sometimes associated with global developmental delay or primary ovarian failure, peripheral hypertonia, seizures, muscle weakness, behavioral abnormalities, and leukoencephalopathy on brain imaging. Serum lactate may or may not be elevated. The disease is caused by variants affecting the gene represented in this entry.
Cofactor. Binds 2 Mg(2+) or Mg(2+) ions per subunit.
Domain organisation. Displays a distorted and non-productive active site that probably switches to a fully productive state only upon association with TRMT10C/MRPP1, HSD17B10/MRPP2 and pre-tRNA substrate.
Induction. Down-regulated following mitochondrial unfolded protein response.
Similarity. Belongs to the PPR family. P subfamily.

Enriched among interaction partners
Reactome pathways and GO biological processes over-represented among this gene’s 132 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
