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].

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].
