The mitochondrial ribosomal protein L42 (MRPL42) is a component of the large subunit of the mitochondrial ribosome, which is essential for protein synthesis within mitochondria. These ribosomes specifically translate mitochondrial DNA-encoded mRNAs, producing subunits of oxidative phosphorylation complexes critical for cellular energy production. MRPL42 antibodies are valuable tools for studying mitochondrial ribosome structure, biogenesis, and function, particularly in the context of mitochondrial disorders, metabolic diseases, and cancer.
MRPL42 antibodies are commonly used in techniques like Western blotting, immunofluorescence, and immunohistochemistry to detect MRPL42 expression levels, subcellular localization, and potential dysregulation in disease models. Many commercial MRPL42 antibodies are raised against specific peptide sequences or recombinant proteins, with validation data including molecular weight confirmation (~40 kDa in humans), mitochondrial enrichment, and knockdown/knockout controls to ensure specificity.
Research involving MRPL42 antibodies has shed light on its role in maintaining mitochondrial proteostasis and its association with pathologies like cardiomyopathy, neurodegeneration, and tumor metabolism. However, users should verify antibody performance in their experimental systems, as cross-reactivity with unrelated proteins or inconsistent detection across species (human, mouse, rat) may occur. Proper mitochondrial fractionation and fixation protocols are often recommended for optimal results.
