背景信息

The RPA70 antibody targets the 70-kDa subunit of Replication Protein A (RPA), a single-stranded DNA (ssDNA)-binding complex critical for DNA metabolism. RPA, composed of RPA70 (RPA1), RPA32 (RPA2), and RPA14 (RPA3), stabilizes ssDNA during replication, repair, and recombination. RPA70 contains key domains for ssDNA binding and protein interactions, making it essential for recruiting repair factors like RAD51 and activating DNA damage response pathways. Antibodies against RPA70 are widely used in research to study DNA replication dynamics, genome stability, and responses to genotoxic stress (e.g., radiation or chemotherapy). They are employed in techniques like Western blotting, immunofluorescence, and chromatin immunoprecipitation (ChIP) to detect RPA70 expression, localization, and post-translational modifications (e.g., phosphorylation during checkpoint activation). Such antibodies help investigate RPA's role in diseases linked to DNA repair defects, such as cancer. Commercial RPA70 antibodies are often validated using knockout cell lines or recombinant proteins to ensure specificity. Clones like 4E4 (mouse monoclonal) or polyclonal variants from rabbits are common. Researchers also use these antibodies to explore RPA70's interaction with viral proteins or its dysregulation in aging, providing insights into therapeutic targets for cancer and neurodegenerative disorders.
