## Summary [PAXX](/details-gene/286257) (Paralog of XRCC4 and XLF), also known as C9orf142, is a protein-coding gene located on chromosome 9q34.3. It functions as a core accessory factor in the classical non-homologous end joining (c-NHEJ) pathway, a major mechanism for repairing DNA double-strand breaks ([Link](https://doi.org/10.1038/cdd.2015.22)). As a component of the '[Nonhomologous end joining complex](/details-go/GO:0070419)', [PAXX](/details-gene/286257) interacts with the Ku70/Ku80 heterodimer and plays a role that partially overlaps with the related factor XLF, particularly during V(D)J recombination in developing lymphocytes ([Link](https://doi.org/10.1016/j.celrep.2016.08.069); [Link](https://doi.org/10.1016/j.celrep.2016.09.026)). Its expression profile shows high significance in various immune cell populations, most notably [plasmacytoid dendritic cell, human](/details-cell/CL0001058), suggesting a critical role in maintaining genomic integrity in the immune system. ## Cellular Roles and Expression Landscape The expression pattern of [PAXX](/details-gene/286257) underscores its fundamental importance in DNA repair across multiple cell lineages, with a pronounced significance in the immune system. **Overall**, the gene exhibits its highest significance in [plasmacytoid dendritic cell, human](/details-cell/CL0001058) (CSI: 65.56), professional antigen-presenting cells specialized in producing type I interferons. High expression is also observed in key cytotoxic and memory lymphocyte populations, including [CD16-positive, CD56-dim natural killer cell, human](/details-cell/CL0000939) (CSI: 29.87) and [central memory CD8-positive, alpha-beta T cell](/details-cell/CL0000907) (CSI: 17.63). Its relevance extends to the myeloid lineage, as shown by its significant expression in [CD14-positive, CD16-positive monocyte](/details-cell/CL0002397) (CSI: 17.42). This broad expression across both innate and adaptive immune cells is consistent with the essential role of NHEJ in processes like V(D)J recombination and general genomic maintenance during immune cell proliferation and response. Beyond the immune system, [PAXX](/details-gene/286257) also shows significant expression in several non-hematopoietic cell types, such as [lung secretory cell](/details-cell/CL1000272) (CSI: 17.90) and [pancreatic acinar cell](/details-cell/CL0002064) (CSI: 14.13). This suggests that its function in preserving genomic stability is a general requirement, particularly in cells with high metabolic or secretory activity which may be more susceptible to DNA damage. ## Pathways and Molecular Function Functional annotation confirms [PAXX](/details-gene/286257)'s role as a central player in the '[Dna damage response](/details-go/GO:0006974)', specifically in '[Double-strand break repair via nonhomologous end joining](/details-go/GO:0006303)'. It localizes to the '[nucleus](/details-go/GO:0005634)' and is recruited to the '[site of double-strand break](/details-go/GO:0035861)' where it functions as a component of the repair machinery. At the molecular level, [PAXX](/details-gene/286257) acts as a molecular adaptor, exhibiting '[identical protein binding](/details-go/GO:0042802)' and '[protein homodimerization activity](/details-go/GO:0042803)'. It is a known member of the '[Ku70:ku80 complex](/details-go/GO:0043564)', associating with the DNA-end binding Ku heterodimer to stabilize the repair complex and promote the ligation of broken DNA ends ([Link](https://doi.org/10.1016/j.celrep.2016.09.026)). Its involvement in DNA repair is crucial for lymphocyte development, where the NHEJ pathway is required to resolve DNA breaks intentionally created during V(D)J recombination to generate diverse antigen receptors ([Link](https://doi.org/10.1016/j.celrep.2016.08.069)). ## Research Directions The established role of [PAXX](/details-gene/286257) in DNA repair, combined with its specific expression patterns, suggests several avenues for future research. **Proposed Hypotheses:** 1. The exceptionally high significance of [PAXX](/details-gene/286257) in [plasmacytoid dendritic cell, human](/details-cell/CL0001058) suggests it is indispensable for maintaining genomic integrity in these cells during their intense antiviral response. It is hypothesized that [PAXX](/details-gene/286257) protects pDCs from DNA damage induced by the high metabolic and replicative stress associated with massive type I interferon production upon viral sensing. 2. The high expression of [PAXX](/details-gene/286257) in long-lived memory lymphocyte populations, such as [central memory CD8-positive, alpha-beta T cell](/details-cell/CL0000907), may be a key factor in their persistence and survival. It is hypothesized that elevated [PAXX](/details-gene/286257)-mediated repair efficiency is critical for preventing the accumulation of DNA damage over the lifespan of these cells, thereby preserving the fidelity of immunological memory. **Key Experimental Approach:** To test the hypothesis regarding the role of [PAXX](/details-gene/286257) in pDCs, a functional genomics approach could be employed. Specifically, CRISPR-Cas9 could be used to knock out [PAXX](/details-gene/286257) in a human pDC cell line (e.g., GEN2.2) or in primary human pDCs isolated from peripheral blood. These knockout and control cells would then be stimulated with a TLR9 agonist (e.g., CpG-A) to mimic a viral infection. The experimental readouts would include: (i) quantification of DNA damage markers, such as γ-H2AX foci, via immunofluorescence microscopy; (ii) assessment of cell viability and apoptosis using flow cytometry; and (iii) measurement of type I interferon (IFN-α) production by ELISA. A significant increase in DNA damage and apoptosis, coupled with a potential defect in IFN-α secretion in knockout cells, would support the hypothesis. **Therapeutic Potential:** Given its central role in the NHEJ pathway, [PAXX](/details-gene/286257) represents a potential therapeutic target for cancer treatment. Many tumors rely on NHEJ to repair DNA damage induced by radiotherapy or chemotherapy. Therefore, the development of small molecule inhibitors targeting [PAXX](/details-gene/286257) could serve as a powerful chemosensitizing or radiosensitizing strategy. Such a therapeutic approach would involve **inhibition** of [PAXX](/details-gene/286257) function. This may be particularly effective in hematological malignancies derived from cell types with high endogenous [PAXX](/details-gene/286257) expression, as these cancers may be uniquely dependent on the c-NHEJ pathway for survival.
