From NCBI Gene:
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 28S subunit protein. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2014]
Required for mitochondrial translation, plays a role in maintaining the stability of the small ribosomal subunit and the 12S rRNA that are required for mitoribosome formation.

- COMBINED OXIDATIVE PHOSPHORYLATION DEFICIENCY 32
Combined oxidative phosphorylation deficiency 32 (COXPD32): An autosomal recessive disorder due to deficiency of mitochondrial respiratory chain complexes, I, III and IV, and characterized by delayed psychomotor development and neurodevelopmental regression. Additional variable symptoms include poor or absent speech, inability to walk, and abnormal movements. [MIM:617664]
