TRMT10C Gene(Protein Coding)TRNA Methyltransferase 10C, Mitochondrial RNase P Subunit

This gene encodes the precursor of a subunit of the mitochondrial ribonuclease P, which is involved in 5' processing of mitochondrial tRNAs. The encoded protein may confer RNA-binding capacity to mitochondrial ribonuclease P and may be essential for transcript processing, RNA modification, translation and mitochondrial respiration.

Mitochondrial tRNA N1-methyltransferase involved in mitochondrial tRNA maturation (PubMed:18984158, PubMed:21593607, PubMed:23042678, PubMed:27132592).
Component of mitochondrial ribonuclease P, a complex composed of TRMT10C/MRPP1, HSD17B10/MRPP2 and PRORP/MRPP3, which cleaves tRNA molecules in their 5'-ends (PubMed:18984158).
Together with HSD17B10/MRPP2, forms a subcomplex of the mitochondrial ribonuclease P, named MRPP1-MRPP2 subcomplex, which displays functions that are independent of the ribonuclease P activity (PubMed:23042678, PubMed:29040705).
The MRPP1-MRPP2 subcomplex catalyzes the formation of N1-methylguanine and N1-methyladenine at position 9 (m1G9 and m1A9, respectively) in tRNAs; TRMT10C/MRPP1 acting as the catalytic N1-methyltransferase subunit (PubMed:23042678).
The MRPP1-MRPP2 subcomplex also acts as a tRNA maturation platform: following 5'-end cleavage by the mitochondrial ribonuclease P complex, the MRPP1-MRPP2 subcomplex enhances the efficiency of 3'-processing catalyzed by ELAC2, retains the tRNA product after ELAC2 processing and presents the nascent tRNA to the mitochondrial CCA tRNA nucleotidyltransferase TRNT1 enzyme (PubMed:29040705).
In addition to tRNA N1-methyltransferase activity, TRMT10C/MRPP1 also acts as a mRNA N1-methyltransferase by mediating methylation of adenosine residues at the N1 position of MT-ND5 mRNA (PubMed:29072297).
Associates with mitochondrial DNA complexes at the nucleoids to initiate RNA processing and ribosome assembly.
