Detailed entry information

Protein Information (annotations from UniProt)

Database IDHIV0001815
UniProt IDQ9H0U6
Primary gene name(s)MRPL18
Synonym gene name(s)unknown
Protein name39S ribosomal protein L18, mitochondrial
Protein functionTogether with thiosulfate sulfurtransferase, TST, acts as a mitochondrial import factor for the cytosolic 5S rRNA. The precursor form shows RNA chaperone activity; is able to fold the 5S rRNA into an import-competent conformation that is recognized by rhodanese, TST. Both the cytoplasmic and mitochondrial forms are able to bind to the helix IV-loop D in the gamma domain of the 5S rRNA. {ECO:0000269|PubMed:21685364}.
Subcellular locationMitochondrion {ECO:0000269|PubMed:25278503}.
