Activity summary

Rad50 is an important component of the MRN complex with its partners MRE11 and NBS1. This protein plays an important role in DNA double-strand break repair and telomere maintenance. Rad50 also known by its molecular weight of approximately 153 kDa possesses ATPase activity that facilitates the bridging of DNA ends during repair processes. It is expressed in a variety of tissues with higher levels observed in rapidly dividing cells such as those found in testes and lymphoid organs.

Biological function summary

Rad50 contributes to genomic stability by participating in non-homologous end joining (NHEJ) and homologous recombination (HR) both of which are DNA repair mechanisms. It is part of the MRN complex a multi-protein assembly that detects DNA breaks and aids in processing and signaling them for repair. This complex acts at the early stages of DNA damage response assisting in the recruitment of other repair enzymes and proteins to the site of DNA lesions.

Pathways

Rad50 is integral to DNA damage response signaling and repair pathways like Ataxia Telangiectasia Mutated (ATM) signaling. The MRN complex activates ATM a kinase that phosphorylates key substrates involved in controlling cell cycle checkpoints and promoting repair of damaged DNA. This relationship positions Rad50 and its complex members as significant participants in maintaining cellular integrity by preventing the accumulation of genetic mutations.

Associated diseases and disorders

Rad50 mutations have links to cancer development due to their effect on genomic instability. Deficiencies in Rad50 or the MRN complex can impair DNA repair leading to an increased risk for neoplastic transformations. Additionally Rad50 interactions with proteins such as p53 a tumor suppressor underline its potential role in the mechanisms behind cancers like breast and ovarian cancer. These connections highlight the importance of Rad50 in understanding disease progression and developing therapeutic strategies.
