Recombinant Mouse Rnf168 Protein, Myc/DDK-tagged

• Cat.No.: Rnf168-5551M
• Product Overview: Purified recombinant protein of mouse full-length ring finger protein 168 (Rnf168), with C-terminal MYC/DDK tag, expressed in HEK293T cells.

Specification

• Description: E3 ubiquitin-protein ligase required for accumulation of repair proteins to sites of DNA damage. Acts with UBE2N/UBC13 to amplify the RNF8-dependent histone ubiquitination. Recruited to sites of DNA damage at double-strand breaks (DSBs) by binding to ubiquitinated histone H2A and H2AX and amplifies the RNF8-dependent H2A ubiquitination, promoting the formation of 'Lys-63'-linked ubiquitin conjugates. This leads to concentrate ubiquitinated histones H2A and H2AX at DNA lesions to the threshold required for recruitment of TP53BP1 and BRCA1. Also recruited at DNA interstrand cross-links (ICLs) sites and promotes accumulation of 'Lys-63'-linked ubiquitination of histones H2A and H2AX, leading to recruitment of FAAP20 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. Also involved in class switch recombination in immune system, via its role in regulation of DSBs repair. Following DNA damage, promotes the ubiquitination and degradation of JMJD2A/KDM4A in collaboration with RNF8, leading to unmask H4K20me2 mark and promote the recruitment of TP53BP1 at DNA damage sites. Not able to initiate 'Lys-63'-linked ubiquitination in vitro; possibly due to partial occlusion of the UBE2N/UBC13-binding region. Catalyzes monoubiquitination of 'Lys-13' and 'Lys-15' of nucleosomal histone H2A (H2AK13Ub and H2AK15Ub, respectively).

Q&As

Are there any current clinical trials involving RNF168 protein?

Clinical trials investigating the potential use of RNF168 as a target for cancer therapy or as a biomarker for cancer prognosis may be underway, but specific details would need to be checked.

How does RNF168 protein contribute to the DNA damage response?

RNF168 plays a role in initiating a signaling cascade that leads to the recruitment of other DNA repair proteins to the site of DNA damage, promoting repair and maintaining genomic stability.

How does RNF168 protein interact with other proteins in the DNA repair pathway?

RNF168 interacts with various proteins involved in the DNA damage response, such as 53BP1 and BRCA1, to coordinate the repair of DNA lesions and maintain genomic stability.

Can mutations in the RNF168 gene be inherited and lead to an increased risk of cancer?

Yes, inherited mutations in the RNF168 gene can increase the risk of developing certain cancers, particularly those associated with DNA damage and repair deficiencies.

Are there any known side effects or toxicities associated with modulating RNF168 activity in cancer therapy?

The potential side effects and toxicities of targeting RNF168 in cancer therapy are still being explored, and would depend on the specific approach and modality used.
