MRPL20 (Mitochondrial Ribosomal Protein L20) is a Protein Coding gene. The MRPL20 gene, located on 1p36.33, is conserved in Rhesus monkey, dog, cow, mouse, rat, chicken, zebrafish, fruit fly, mosquito, A.thaliana, rice, and frog. MRPL20 belongs to the bacterial ribosomal protein bL20 family. This gene encodes a 39S subunit protein and is widely expressed in kidney, fat, and other tissues. A pseudogene corresponding to this gene is found on chromosome 21q. Alternative splicing results in multiple transcript variants encoding different isoforms. Among its related pathways are Organelle biogenesis and maintenance and Viral mRNA Translation. 241 organisms have orthologs with the human gene MRPL20.
