Mammalian mitochondrial ribosomal proteins are encoded by nuclear genes and help in protein synthesis within themitochondrion. Mitochondrial ribosomes (mitoribosomes) consist of a small 28S subunit and a large 39S subunit. Theyhave 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 inbiochemical properties, which prevents easy recognition by sequence homology. This gene encodes a 39S subunit protein.The gene is biallelically expressed, despite its location within a region of imprinted genes on chromosome 11.(provided by RefSeq)
