Functioni

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.2 Publications

Interactioni

Subunit structurei

Component of the mitochondrial large ribosomal subunit (mt-LSU). Mature yeast 74S mitochondrial ribosomes consist of a small (37S) and a large (54S) subunit. The 37S small subunit contains a 15S ribosomal RNA (15S mt-rRNA) and 34 different proteins. The 54S large subunit contains a 21S rRNA (21S mt-rRNA) and 46 different proteins.3 Publications

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
