CC -!- FUNCTION: Component of the mitochondrial ribosome (mitoribosome), a
CC dedicated translation machinery responsible for the synthesis of
CC mitochondrial genome-encoded proteins, including at least some of the
CC essential transmembrane subunits of the mitochondrial respiratory
CC chain. The mitoribosomes are attached to the mitochondrial inner
CC membrane and translation products are cotranslationally integrated into
CC the membrane. {ECO:0000305|PubMed:24675956,
CC ECO:0000305|PubMed:25609543}.
CC -!- SUBUNIT: Component of the mitochondrial large ribosomal subunit (mt-
CC LSU). Mature yeast 74S mitochondrial ribosomes consist of a small (37S)
CC and a large (54S) subunit. The 37S small subunit contains a 15S
CC ribosomal RNA (15S mt-rRNA) and 34 different proteins. The 54S large
CC subunit contains a 21S rRNA (21S mt-rRNA) and 46 different proteins.
CC {ECO:0000269|PubMed:12392552, ECO:0000269|PubMed:2060626,
CC ECO:0000269|PubMed:24675956}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion {ECO:0000269|PubMed:14562095,
CC ECO:0000269|PubMed:14576278}. Note=Mitoribosomes are tethered to the
CC mitochondrial inner membrane and spatially aligned with the membrane
CC insertion machinery through two distinct membrane contact sites, formed
CC by the 21S rRNA expansion segment 96-ES1 and the inner membrane protein
CC MBA1. {ECO:0000269|PubMed:25609543}.
CC -!- MISCELLANEOUS: Present with 350 molecules/cell in log phase SD medium.
CC {ECO:0000269|PubMed:14562106}.
CC -!- SIMILARITY: Belongs to the mitochondrion-specific ribosomal protein
CC mL58 family. {ECO:0000305}.
