XRCC5 (X-ray Repair,Complementing Defective ,In Chinese Hamster, 5), also known as Ku80 or Ku86, is a protein that in humans, is encoded by the XRCC5 gene. The XRCC5 gene encodes the 80-kD subunit of the Ku autoantigen, a heterodimer which contributes to genomic integrity through its ability to bind DNA double-strand breaks and facilitate repair by the nonhomologous end joining (NHEJ) pathway. The XRCC5 gene is mapped to 2q35. Human colon cancer cells heterozygous for Ku86 are haploinsufficient with an increase in polyploid cells, a reduction in cell proliferation, elevated p53 levels, and a slight hypersensitivity to ionizing radiation. Functional inactivation of the second Ku86 allele results in cells with a drastically reduced doubling time. The Ku86 locus is essential in human somatic tissue culture cells by experiments demonstration. A rare microsatellite polymorphism in XRCC5 is associated with cancer in patients of varying radiosensitivity. Functional note: Single-stranded DNA-dependent ATP-dependent helicase. Has a role in chromosome translocation. The DNA helicase II complex binds preferentially to fork-like ends of double-stranded DNA in a cell cycle-dependent manner. It works in the 3'-5' ion. Binding to DNA may be mediated by XRCC6. Involved in DNA non-homologous end joining (NHEJ) required for double-strand break repair and V (D)J recombination. The XRCC5\/6 dimer acts as regulatory subunit of the DNA-dependent protein kinase complex DNA-PK by increasing the affinity of the catalytic subunit PRKDC to DNA by 100-fold. The XRCC5\/6 dimer is probably involved in stabilizing broken DNA ends and bringing them together. The assembly of the DNA-PK complex to DNA ends is required for the NHEJ ligation step. In association with NAA15, the XRCC5\/6 dimer binds to the osteocalcin promoter and activates osteocalcin expression. The XRCC5\/6 dimer probably also acts as a 5'- deoxyribose-5-phosphate lyase (5'-dRP lyase), by catalyzing the beta-elimination of the 5' deoxyribose-5-phosphate at an abasic site near double-strand breaks. XRCC5 probably acts as the catalytic subunit of 5'-dRP activity, and allows to 'clean' the termini of abasic sites, a class of nucleotide damage commonly associated with strand breaks, before such broken ends can be joined. The XRCC5\/6 dimer together with APEX1 acts as a negative regulator of transcription. . Reported localization: Nucleus. Nucleus, nucleolus. Chromosome. Expression\/tissue context: Expressed in plasma cells in rheumatoid synovium (PubMed:11460154). Over-expressed in primary breast cancer and metastatic breast cancer cells (PubMed:25280941). Isoform 1 and isoform 2 are expressed at higher level in proliferating as compared to confluent quiescent endothelial cells (PubMed:19416856). .\u003c\/p\u003e \u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eDNA\/RNA: Researchers commonly examine how XRCC5 (X-ray repair cross-complementing protein 5) relates to this theme using model systems and orthogonal readouts.\u003c\/li\u003e\n\u003cli\u003eEpigenetics and Nuclear Signaling: Researchers commonly examine how XRCC5 (X-ray repair cross-complementing protein 5) relates to this theme using model systems and orthogonal readouts.\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eCommon research applications\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eWestern blotting: compare relative XRCC5 (X-ray repair cross-complementing protein 5) levels across conditions; band patterns may reflect isoforms and processing.\u003c\/li\u003e\n\u003cli\u003eIHC\/IHC-F: assess spatial distribution of XRCC5 (X-ray repair cross-complementing protein 5) across tissue regions and cell types using matched controls.\u003c\/li\u003e\n\u003cli\u003eIF\/ICC: evaluate subcellular localization and co-localization patterns; signal can depend on fixation\/permeabilization and epitope accessibility.\u003c\/li\u003e\n\u003cli\u003eFlow cytometry: quantify target-positive populations and shifts in expression; gating strategy and background staining controls are essential.\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e \u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eSpecificity notes:\u003c\/strong\u003e No cross reactivity with other proteins.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eCross-reactivity:\u003c\/strong\u003e No cross-reactivity with other proteins\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eFamily \/ similarity context:\u003c\/strong\u003e Belongs to the ku80 family.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eIsoforms and PTMs:\u003c\/strong\u003e Apparent size and signal patterns can differ across splice isoforms, proteolytic processing, and post-translational modifications.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eControls:\u003c\/strong\u003e Include an isotype control (as relevant), no-primary control for imaging, and orthogonal validation such as KD\/KO samples when available.\u003c\/li\u003e \u003c\/ul\u003e \u003c!-- Sources (internal): - UniProt entry for P13010: https:\/\/www.uniprot.org\/uniprotkb\/P13010\/entry - PubMed search (XRCC5): https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=XRCC5 - NCBI Gene search (XRCC5): https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=XRCC5 - Antibody validation concepts (NIH): https:\/\/www.nih.gov\/research-training\/rigor-reproducibility --\u003e","brand":"Boster Bio","offers":[{"title":"100 ug\/vial \/ Unconjugated","offer_id":53066822615405,"sku":"PB9464","price":370.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Biotin","offer_id":53067010376045,"sku":"PB9464-Biotin","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Cy3","offer_id":53067010408813,"sku":"PB9464-Cy3","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro488","offer_id":53067010441581,"sku":"PB9464-Fluoro488","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro550","offer_id":53067010474349,"sku":"PB9464-Fluoro550","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro594","offer_id":53067010507117,"sku":"PB9464-Fluoro594","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ FITC","offer_id":53067010539885,"sku":"PB9464-FITC","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ HRP","offer_id":53067010572653,"sku":"PB9464-HRP","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ APC","offer_id":53067010605421,"sku":"PB9464-APC","price":820.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ PE","offer_id":53067010638189,"sku":"PB9464-PE","price":820.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro647","offer_id":53067010670957,"sku":"PB9464-Fluoro647","price":670.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Carrier Free","offer_id":53067010703725,"sku":"PB9464-carrier-free","price":370.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/pb9464-ku80-primary-antibodies-wb-testing-1.jpg?v=1772608156","url":"https:\/\/www.ebiohippo.com\/products\/anti-ku80-xrcc5-antibody-picoband-bha21000358","provider":"BioHippo","version":"1.0","type":"link"}
