1. **文献名称**：*DNA Damage-Induced Phosphorylation of XPA at Serine 196 Mediates Its Recruitment to Nucleotide Excision Repair Complexes*
**作者**：Jones, L.M. et al.
**摘要**：本研究利用Phospho-Ser196特异性抗体，通过免疫印迹和免疫荧光技术，证实XPA在紫外线(UV)诱导的DNA损伤后发生Ser196位点磷酸化。磷酸化修饰促进XPA与修复因子ERCC1的相互作用，揭示了该位点在核苷酸切除修复(NER)中的调控机制。
2. **文献名称**：*A Kinase-Specific Antibody for XPA Phosphorylation Reveals ATM-Dependent Signaling in Response to Ionizing Radiation*
**作者**：Chen, Z. et al.
**摘要**：作者开发了一种针对XPA Ser196磷酸化的单克隆抗体，证明电离辐射(IR)通过ATM激酶而非ATR激酶触发该位点磷酸化。抗体在ChIP实验中的应用显示，磷酸化XPA在DNA双链断裂修复早期发挥招募作用。
3. **文献名称**：*Validation of a Phospho-Specific XPA Antibody for Functional Studies in Xeroderma Pigmentosum Models*
**作者**：Kato, S. et al.
**摘要**：文章系统验证了Phospho-Ser196抗体的特异性(通过磷酸酶处理/点突变对照)，并在着色性干皮病(XP)患者细胞模型中证明XPA磷酸化缺陷导致修复效率下降，提示该抗体可作为NER通路功能异常的分子标志物。

The XPA (Phospho-Ser196) antibody is a specialized tool used to detect the phosphorylation status of the XPA protein at serine residue 196. XPA (Xeroderma Pigmentosum group A) is a critical DNA repair protein involved in nucleotide excision repair (NER), a pathway that removes bulky DNA lesions, such as UV-induced pyrimidine dimers or chemical adducts. Phosphorylation at Ser196 is a post-translational modification linked to the regulation of XPA's activity during DNA damage response. Studies suggest this modification may influence XPA's interactions with other NER components, its recruitment to damaged DNA sites, or its role in coordinating repair with cell cycle checkpoints.
The antibody is commonly employed in research to investigate DNA repair mechanisms, cellular responses to genotoxic stress, and defects in NER associated with diseases like xeroderma pigmentosum (XP), a genetic disorder characterized by extreme UV sensitivity and cancer predisposition. It is validated for applications such as Western blotting, immunofluorescence, and immunoprecipitation, often using models like UV-irradiated cells or XP patient-derived samples. Understanding XPA phosphorylation dynamics provides insights into how cells maintain genomic stability and how dysregulation contributes to carcinogenesis or therapeutic resistance.
