MRM1 (Mitochondrial RNA Methyltransferase 1) is a conserved eukaryotic protein involved in post-transcriptional RNA modifications within mitochondria. It encodes a mitochondrial S-adenosylmethionine-dependent methyltransferase responsible for catalyzing the 2'-O-methylation of the 18S ribosomal RNA (rRNA) at position U1369 in humans (equivalent to position U2790 in yeast). This modification is critical for maintaining mitochondrial ribosomal integrity, translational fidelity, and overall mitochondrial protein synthesis efficiency.
Discovered through homology studies of yeast mitochondrial RNA modification systems, MRM1 operates as part of a protein complex, often interacting with MRM2 and MRM3 in higher eukaryotes. Its enzymatic activity ensures proper rRNA folding and ribosome assembly, which are essential for mitochondrial-encoded oxidative phosphorylation (OXPHOS) components. Dysregulation of MRM1 has been linked to mitochondrial dysfunction, contributing to metabolic disorders, neurodegenerative diseases, and cancer progression.
Recombinant MRM1 protein is typically produced using heterologous expression systems like E. coli or mammalian cell cultures, enabling biochemical characterization and structural studies. Crystallographic analyses reveal a class I methyltransferase fold with conserved catalytic motifs. Current research focuses on its role in cellular energy metabolism, disease mechanisms, and potential as a therapeutic target. The recombinant protein serves as a tool for investigating RNA modification networks and developing small-molecule modulators of mitochondrial translation.
