MRPS5
Description
The MRPS5 (mitochondrial ribosomal protein S5) is a protein-coding gene located on chromosome 2.
MRPS5, also known as uS5m, is a protein that in humans is encoded by the MRPS5 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 that belongs to the ribosomal protein S5P family. Pseudogenes corresponding to this gene are found on chromosomes 4q, 5q, and 18q.
MRPS5, also known as uS5m, is a protein that functions as a component of the mitochondrial small ribosomal subunit (mt-SSU). It plays a crucial role in protein synthesis within the mitochondria, contributing to the assembly and function of the mitochondrial ribosome.
MRPS5 is also known as MRP-S5, S5mt, uS5m.
