Mitochondrial ribosome protein L34 (mRpL34) is involved in ribosomal protein translation, encoded by a class of mitochondrial genes responsible for mitochondrial diseases that typically lead to muscle and brain disorders, and regulates differentiation in the Drosophila eye, coupling with the expression of dystroglycan (DG) [70]. This evidence concerns the gene MRPL34 and inborn mitochondrial metabolism disorder.
