The RNF8 (Ab-137) antibody is a widely used tool to study the function of RNF8 (Ring Finger Protein 8), an E3 ubiquitin ligase critical in DNA damage response (DDR) and genome maintenance. RNF8 operates by forming a complex with RNF168 to catalyze ubiquitination of histones H2A and H2AX at sites of DNA double-strand breaks (DSBs), facilitating recruitment of repair proteins like BRCA1 and 53BP1. This ubiquitin-dependent signaling cascade is essential for efficient repair, cell cycle checkpoint activation, and prevention of genomic instability.
The Ab-137 antibody, often raised against a specific epitope or phosphorylated residue (e.g., Ser139 in γ-H2AX context), enables detection of RNF8's activation or interaction partners in techniques such as Western blotting, immunofluorescence, or chromatin immunoprecipitation (ChIP). Its specificity helps researchers dissect RNF8's role in DDR pathways, meiosis, and telomere maintenance. Studies using this antibody have clarified RNF8's involvement in cancer progression, as its dysregulation is linked to chemotherapy resistance, defective DNA repair, and tumorigenesis.
Validated in knockout or siRNA-treated models, Ab-137 ensures reliable detection of endogenous RNF8 across human and murine systems. Its application extends to exploring RNF8's non-canonical roles, such as in viral infection responses or transcriptional regulation, underscoring its versatility in both basic and translational research.
