28S ribosomal protein S5, mitochondrial is a protein that in humans is encoded by the MRPS5 gene.[3]

Function[edit]

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 that belongs to the ribosomal protein S5P family. Pseudogenes corresponding to this gene are found on chromosomes 4q, 5q, and 18q.[3]

Model organisms[edit]

Model organisms have been used in the study of MRPS5 function. A conditional knockout mouse line called Mrps5tm1b(EUCOMM)Wtsi was generated at the Wellcome Trust Sanger Institute.[4] Male and female animals underwent a standardized phenotypic screen[5] to determine the effects of deletion.[6][7][8][9] Additional screens performed: - In-depth immunological phenotyping[10]
