Histone H2A.X is phosphorylated on S139, termed gamma H2A.X, at sites of DNA damage. DNA DSB repair by NHEJ requires Ku70\/Ku80 heterodimer binding to the DSB, as well as DNA Ligase IV for ligation of DNA ends.\u003cbr\u003e\nThis panel contains 5 recombinant rabbit monoclonal antibodies.

Ku70 also known as XRCC6 is a 70 kDa protein and Ku80 or XRCC5 is approximately 80 kDa. Both proteins are ubiquitously expressed meaning they are found in various cell types. These proteins form a heterodimer complex with DNA Ligase IV that recognizes and aligns broken DNA ends facilitating repair. Histone H2A.X variants including gamma H2A.X become phosphorylated upon DNA damage and serve as a signal for recruiting repair machinery to the double-strand breaks.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nKu70 and Ku80 act as a DNA-binding complex that is important in double-strand break repair via the non-homologous end joining mechanism. The Ku heterodimer associates with DNA Ligase IV in a multiprotein complex to bridge and ligate broken DNA strands. Histone H2A.X including its phosphorylated form gamma H2A.X marks sites of DNA damage. The H2A.X variants contribute to chromatin remodeling making the DNA accessible to repair proteins and maintaining genomic integrity.\u003cbr\u003e\nPathways\u003cbr\u003e\nNon-homologous end joining is one critical pathway where Ku70 and Ku80 are involved. This pathway operates independently of a homologous template and is essential for repairing DNA double-strand breaks. Another related pathway is the cell cycle checkpoint signaling where gamma H2A.X's phosphorylation helps signal and stall the cell cycle allowing time for repair. In these pathways Ku proteins and DNA Ligase IV work alongside proteins such as DNA-PKcs and XRCC4 to ensure effective DNA repair.\u003cbr\u003e\nDisruptions in the non-homologous end joining pathway connect to cancer development and immunodeficiencies. Defects in Ku70 Ku80 or DNA Ligase IV function can lead to genomic instability contributing to the onset of various cancers. Mutations in these proteins also relate to conditions like severe combined immunodeficiency (SCID) as ineffective DNA repair impairs lymphocyte development. These connections highlight the critical roles these proteins play in disease prevention.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46847586107561,"sku":"ab213658","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/ar\/products\/abcam-ab213658","provider":"Iright","version":"1.0","type":"link"}
