CC -!- FUNCTION: Mitochondrial tRNA N(1)-methyltransferase involved in
CC mitochondrial tRNA maturation. Component of mitochondrial ribonuclease
CC P, which cleaves tRNA molecules in their 5'-ends. Together with
CC hsd17b10/mrpp2, forms a subcomplex of the mitochondrial ribonuclease P,
CC named MRPP1-MRPP2 subcomplex, which displays functions that are
CC independent of the ribonuclease P activity. The MRPP1-MRPP2 subcomplex
CC catalyzes the formation of N(1)-methylguanine and N(1)-methyladenine at
CC position 9 (m1G9 and m1A9, respectively) in tRNAs; trmt10c/mrpp1 acting
CC as the catalytic N(1)-methyltransferase subunit. The MRPP1-MRPP2
CC subcomplex also acts as a tRNA maturation platform: following 5'-end
CC cleavage by the mitochondrial ribonuclease P complex, the MRPP1-MRPP2
CC subcomplex enhances the efficiency of 3'-processing catalyzed by ELAC2,
CC retains the tRNA product after elac2 processing and presents the
CC nascent tRNA to the mitochondrial CCA tRNA nucleotidyltransferase TRNT1
CC enzyme. In addition to tRNA N(1)-methyltransferase activity,
CC trmt10c/mrpp1 also acts as a mRNA N(1)-methyltransferase by mediating
CC methylation of adenosine residues at the N(1) position of MT-ND5 mRNA.
CC {ECO:0000250|UniProtKB:Q7L0Y3}.
