- Background
- E3 ubiquitin-protein ligase that plays a key role in DNA damage signaling via 2 distinct roles: by mediating the 'Lys-63'-linked ubiquitination of histones H2A and H2AX and promoting the recruitment of DNA repair proteins at double-strand breaks(DSBs) sites, and by catalyzing 'Lys-48'-linked ubiquitination to remove target proteins from DNA damage sites. Following DNA DSBs, it is recruited to the sites of damage by ATM-phosphorylated MDC1 and catalyzes the 'Lys-63'-linked ubiquitination of histones H2A and H2AX, thereby promoting the formation of TP53BP1 and BRCA1 ionizing radiation-induced foci(IRIF). Also controls the recruitment of UIMC1-BRCC3(RAP80-BRCC36) and PAXIP1/PTIP to DNA damage sites. Also recruited at DNA interstrand cross-links(ICLs) sites and catalyzes 'Lys-63'-linked ubiquitination of histones H2A and H2AX, leading to recruitment of FAAP20/C1orf86 and Fanconi anemia(FA) complex, followed by interstrand cross-link repair. H2A ubiquitination also mediates the ATM-dependent transcriptional silencing at regions flanking DSBs in cis, a mechanism to avoid collision between transcription and repair intermediates. Promotes the formation of 'Lys-63'-linked polyubiquitin chains via interactions with the specific ubiquitin-conjugating UBE2N/UBC13 and ubiquitinates non-histone substrates such as PCNA. Substrates that are polyubiquitinated at 'Lys-63' are usually not targeted for degradation. Also catalyzes the formation of 'Lys-48'-linked polyubiquitin chains via interaction with the ubiquitin-conjugating UBE2L6/UBCH8, leading to degradation of substrate proteins such as CHEK2, JMJD2A/KDM4A and KU80/XRCC5: it is still unclear how the preference toward 'Lys-48'-versus 'Lys-63'-linked ubiquitination is regulated but it could be due to RNF8 ability to interact with specific E2 specific ligases. For instance, interaction with phosphorylated HERC2 promotes the association between RNF8 and UBE2N/UBC13 and favors the specific formation of 'Lys-63'-linked ubiquitin chains. Promotes non-homologous end joining(NHEJ) by promoting the 'Lys-48'-linked ubiquitination and degradation the of KU80/XRCC5. Following DNA damage, mediates the ubiquitination and degradation of JMJD2A/KDM4A in collaboration with RNF168, leading to unmask H4K20me2 mark and promote the recruitment of TP53BP1 at DNA damage sites. In addition to its function in damage signaling, also plays a role in higher-order chromatin structure by mediating extensive chromatin decondensation. Involved in the activation of ATM by promoting histone H2B ubiquitination, which indirectly triggers histone H4 'Lys-16' acetylation(H4K16ac), establishing a chromatin environment that promotes efficient activation of ATM kinase. Required in the testis, where it plays a role in the replacement of histones during spermatogenesis. At uncapped telomeres, promotes the joining of deprotected chromosome ends by inducing H2A ubiquitination and TP53BP1 recruitment, suggesting that it may enhance cancer development by aggravating telomere-induced genome instability in case of telomeric crisis. Promotes the assembly of RAD51 at DNA DSBs in the absence of BRCA1 and TP53BP1 Also involved in class switch recombination in immune system, via its role in regulation of DSBs repair. May be required for proper exit from mitosis after spindle checkpoint activation and may regulate cytokinesis. May play a role in the regulation of RXRA-mediated transcriptional activity. Not involved in RXRA ubiquitination by UBE2E2.

Ordering & Delivery
How do I place an order?
Use the Inquiry button on this page or write to tekintolga89@gmail.com. Include the catalogue number and the quantity you need.
What is the dispatch time?
In-stock items are dispatched within 1-3 business days. Items that need to be produced take longer; we confirm the date when you order.
Do you ship outside Türkiye?
Shipping is arranged case by case. Contact us with the destination and we will quote carriage and lead time.
Storage & Handling
How should an unopened kit be stored?
At 2-8 °C unless the datasheet says otherwise. Do not freeze a kit that is not marked for freezing.
How long is an opened kit stable?
It depends on the component. The Kit Components table on this page lists the storage condition for each item after opening.
What should I do if the shipment arrives warm?
Photograph the package and contact us the same day. Do not use the kit until we have confirmed it is still within specification.
Assay Questions
Which sample types can I use?
The Sample Type row in the specifications above lists the validated matrices for this product. Other matrices need validation on your side.
My background is too high. What should I check?
The usual causes are insufficient washing, contaminated buffers, or too much detection antibody. Our Protocol pages cover the full troubleshooting sequence.
Can I run fewer wells than the kit provides?
Yes. Dismountable microplates let you use part of a plate and reseal the rest with the desiccant supplied.
Technical Support
Something did not work. What do you need from me?
Send the catalogue number, the lot, your protocol deviations and the raw OD values. That is usually enough to identify the cause.
Do you provide a certificate of analysis?
Yes, per lot. Ask for it with the catalogue number and lot number.
