Members of this family are components of the mitochondrial large ribosomal subunit. Mature mitochondrial ribosomes consist of a small (37S) and a large (54S) subunit. The 37S subunit contains at least 33 different proteins and 1 molecule of RNA (15S). The 54S subunit contains at least 45 different proteins and 1 molecule of RNA (21S) [1][2].
