General description

Mammalian mitochondrial ribosomal proteins are encoded by nuclear genes and help in protein synthesis within the mitochondrion. Mitochondrial ribosomes (mitoribosomes) consist of a small 28S subunit and a large 39S subunit. They have an estimated 75% protein to rRNA composition compared to prokaryotic ribosomes, where this ratio is reversed. Another difference between mammalian mitoribosomes and prokaryotic ribosomes is that the latter contain a 5S rRNA. Among different species, the proteins comprising the mitoribosome differ greatly in sequence, and sometimes in biochemical properties, which prevents easy recognition by sequence homology. This gene encodes a 39S subunit protein which forms homodimers. In prokaryotic ribosomes, two L7/L12 dimers and one L10 protein form the L8 protein complex. (provided by RefSeq)

Biochem/physiol Actions

MRPL12 (mitochondrial ribosomal protein) is involved in the mitochondrial translation. It directly interacts with the mitochondrial RNA polymerase (POLRMT) and triggers the mitochondrial transcriptional process. Research shows that the interaction between MRPL12 and POLRMT indicates its participation in the regulatory mechanism that coordinates mitochondrial transcription with translation and/or ribosome biogenesis during human mitochondrial gene expression. Study shows that MRPL12 may be involved in the differentiation of colonic epithelial cells and its reduced mitochondrial activity have been shown to be linked with tumor formation. It has been reported that mutated expression of MRPL12 associates with the growth retardation, neurological deterioration and mitochondrial translation deficiency.

Multiple respiratory chain deficiencies represent a common cause of mitochondrial diseases and are associated with a wide range of clinical symptoms. We report a subject, born to consanguineous parents, with growth retardation and neurological deterioration. Multiple respiratory chain deficiency was
