MRPS5抗体

The mitochondrial ribosomal protein S5 (MRPS5) is a key component of the small subunit of the mitochondrial ribosome (28S), which is essential for protein synthesis within mitochondria. Encoded by nuclear DNA, MRPS5 is imported into mitochondria, where it facilitates the assembly and stability of the mitoribosome, ensuring proper translation of mitochondrial DNA-encoded mRNAs. These mRNAs primarily code for subunits of the oxidative phosphorylation (OXPHOS) complexes, critical for cellular energy production. MRPS5 antibodies are widely used tools in mitochondrial research to study ribosome biogenesis, mitochondrial translation defects, and their implications in human diseases. Dysregulation of MRPS5 has been linked to mitochondrial disorders, cancer, and neurodegenerative conditions, as impaired mitochondrial protein synthesis disrupts OXPHOS, leading to bioenergetic failure. Commercially available MRPS5 antibodies (polyclonal or monoclonal) are validated for applications like Western blotting, immunofluorescence, and immunohistochemistry, aiding in the detection of protein expression levels, subcellular localization, and pathological alterations. Recent studies also explore MRPS5's role in apoptosis, metabolic reprogramming, and its potential as a biomarker for cancer prognosis. Its conservation across species underscores its fundamental role in mitochondrial function, making MRPS5 antibodies valuable for both basic and translational research.
