The proteins in this family are located in the mitochondrion. The family includes ribosomal protein L51, and S25. This family also includes mitochondrial NADH-ubiquinone oxidoreductase B8 subunit (CI-B8) EC:1.6.5.3. It is not known whether all members of this family form part of the NADH-ubiquinone oxidoreductase and whether they are also all ribosomal proteins. Structurally related to thioredoxin-fold.
Large ribosomal subunit protein uL24, C-terminal domain
This entry describes the C-terminal domain in large ribosomal subunit protein uL24 (also known as RPL26). RPL26 is one of the proteins from the large ribosomal subunit. In their mature form, these proteins have 103 to 150 amino-acid residues. RPL26 m ...
This entry describes the C-terminal domain in large ribosomal subunit protein uL24 (also known as RPL26). RPL26 is one of the proteins from the large ribosomal subunit. In their mature form, these proteins have 103 to 150 amino-acid residues. RPL26 makes very minor contributions to the biogenesis structure, and function of 60s ribosomal subunits [1]. However, RPL24 is essential to generate the first intermediate during 50s ribosomal subunits assembly [2]. RPL26 have an extra-ribosomal function to enhances p53 translation after DNA damage [3].
This domain is found in peptide chain release factors such as RF-1 (Swiss:P07011) and RF-2 (Swiss:P07012), and a number of smaller proteins of unknown function such as Swiss:P40711. This domain contains the peptidyl-tRNA hydrolase activity. The domai ...
This domain is found in peptide chain release factors such as RF-1 (Swiss:P07011) and RF-2 (Swiss:P07012), and a number of smaller proteins of unknown function such as Swiss:P40711. This domain contains the peptidyl-tRNA hydrolase activity. The domain contains a highly conserved motif GGQ, where the glutamine is thought to coordinate the water that mediates the hydrolysis.

Tim44 is an essential component of the machinery that mediates the translocation of nuclear-encoded proteins across the mitochondrial inner membrane [1]. Tim44 is thought to bind phospholipids of the mitochondrial inner membrane both by electrostatic interactions and by penetrating the polar head group region [1]. This family includes the C-terminal region of Tim44 that has been shown to form a stable proteolytic fragment in yeast. This region is also found in a set of smaller bacterial proteins. The molecular function of the bacterial members of this family is unknown but transport seems likely. The crystal structure of the C terminal of Tim44 has revealed a large hydrophobic pocket which might play an important role in interacting with the acyl chains of lipid molecules in the mitochondrial membrane [3].

This domain of unknown function is found at the C terminal end of Mitochondrial small ribosomal subunit protein mS38, also known as Mitochondrial mRNA-processing protein COX24 in yeast which is involved in the splicing of the COX1 mRNA [1]. COX24 is a component of the mitochondrial ribosome (mitoribosome), 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 [2,3]. This domain is also found in COX24 mammalian homologue Aurora kinase A-interacting protein [4]. This entry also includes uncharacterised proteins from bacteria.
