Research Explores FMT's Role in mRNA Translation Near Mitochondria
Recent research has delved into the role of CLU family proteins, specifically plant FMT, in mRNA translation near mitochondria. FMT, an RNA-binding protein, interacts with ribosomes and mRNA encoding mitochondrial proteins, potentially influencing their translation. The study involved proximity labelling and RNA immunoprecipitation experiments to identify candidate protein and mRNA interactors. Among 149 candidate protein interactors, 53 were depleted when treated with a translation inhibitor, indicating interactions through nascent polypeptide chains. FMT's interaction with ribosomal proteins is weak, but several NAC components are enriched, suggesting an indirect ribosomal association. The research points to FMT's role in organellar precursor sorting, with implications for mitochondrial fission.
