Protein: Large ribosomal subunit protein uL3m (54S ribosomal protein L9, mitochondrial) (YmL9) (P31334)
Organism: Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Function: Component of the mitochondrial ribosome (mitoribosome), a dedicated translation machinery responsible for the synthesis of mitochondrial genome-encoded proteins, including at least some of the essential transmembrane subunits of the mitochondrial respiratory chain. The mitoribosomes are attached to the mitochondrial inner membrane and translation products are cotranslationally integrated into the membrane.
Subcellular location: Mitochondrion {ECO:0000269|PubMed:14562095, ECO:0000269|PubMed:14576278}. Note=Mitoribosomes are tethered to the mitochondrial inner membrane and spatially aligned with the membrane insertion machinery through two distinct membrane contact sites, formed by the 21S rRNA expansion segment 96-ES1 and the inner membrane protein MBA1. {ECO:0000269|PubMed:25609543}.
