MRPL23 (Mitochondrial Ribosomal Protein L23) is a key component of the mitochondrial ribosome, specifically the large (39S) subunit of the mitoribosome. Encoded by the nuclear gene *MRPL23*, this protein is synthesized in the cytoplasm and transported into mitochondria, where it participates in mitochondrial protein synthesis. Mitochondrial ribosomes are responsible for translating the 13 mitochondrially encoded subunits of the oxidative phosphorylation (OXPHOS) complexes, essential for cellular energy production via ATP generation. MRPL23. as a structural and functional element of the mitoribosome, contributes to ribosome assembly, stability, and proper interaction with translation factors or transfer RNAs (tRNAs).
Mutations or dysregulation in MRPL23 have been linked to mitochondrial dysfunction, which underlies various disorders, including metabolic diseases, neurodegenerative conditions, and cancer. Studies suggest that abnormal expression of MRPL23 may impair mitochondrial respiration, leading to reduced ATP output and increased oxidative stress. Recombinant MRPL23 protein, produced through heterologous expression systems (e.g., *E. coli* or mammalian cells), is widely used to investigate its structural role, interactions within the mitoribosome, and pathological mechanisms. It also serves as a tool for screening therapeutic agents targeting mitochondrial translation defects. Research on MRPL23 enhances understanding of mitochondrial biology and its implications in human health and disease.
