This is a family of transcriptional regulators. In mammals, it activates the transcription of mitochondrially-encoded COX1 [2]. In bacteria, it negatively regulates the quorum-sensing response regulator by binding to its promoter region [3]. This entry represents the second and third domains in this protein, with one domain nested within the other.
Large ribosomal subunit protein mL44, endonuclease domain
Large ribosomal subunit protein mL44 (RM44) is a component of the 39S subunit of mitochondrial ribosome. It may play a role in the assembly/stability of nascent mitochondrial polypeptides exiting the ribosome. This entry represents the endonuclease ( ...

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].
Large ribosomal subunit protein bL9m C-terminal domain
This entry represents a presumed domain found at the C-terminal of the large ribosomal subunit protein bL9m (mitochondrial) from animals. This domain may adopt a similar fold than prokaryotic large ribosomal subunit protein bL9.
Large ribosomal subunit protein bL9m N-terminal domain
This is a presumed domain found at the very N-terminal of Large ribosomal subunit protein bL9m from animals, a structural component of the large subunit of the ribosome. According to structure predictions, it may consist in a hairpin with two beta-sh ...
This is a presumed domain found at the very N-terminal of Large ribosomal subunit protein bL9m from animals, a structural component of the large subunit of the ribosome. According to structure predictions, it may consist in a hairpin with two beta-sheets at each ends connected by a loop.

The 39S ribosomal protein appears to be a subunit of one of the larger mitochondrial 66S or 70S units [1]. Under conditions of ethanol-stress in rats the larger subunit is largely dissociated into its smaller components [2]. In E. coli, in the absence of the enzyme pseudouridine synthase (RluD) synthase, there is an accumulation of 50S and 30S subunits and the appearance of abnormal particles (62S and 39S), with concomitant loss of 70S ribosomes [2].
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].

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 member ...
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.
