Other Information

**Key characteristics**: - DDB2 is a large protein with a molecular weight of approximately 120 kDa. - It is a member of the DNA damage binding protein family. - DDB2 is highly expressed in cells that are involved in DNA repair, such as corneal endothelial cells, basal epithelial cells of the tracheobronchial tree, mural cells, and corneal epithelial cells. - It is also expressed in cells that are involved in cell cycle regulation and apoptosis. **Pathways and functions:** - DDB2 is involved in the initiation of the gg-ner pathway, a DNA repair pathway that is triggered by DNA damage. - It binds to DNA damage response proteins, such as DNA repair proteins and cell cycle proteins, and recruits them to the site of DNA damage. - DDB2 also plays a role in the regulation of cell cycle progression and apoptosis. - It inhibits the activation of the DNA repair protein ATM, which is a key regulator of the cell cycle. - By binding to ATM and preventing its activation, DDB2 allows cells to repair DNA damage without compromising cell cycle progression. **Clinical significance:** - Mutations in DDB2 have been linked to an increased risk of certain types of cancer, including lung cancer, colorectal cancer, and breast cancer. - Targeting DDB2 has been explored as a therapeutic strategy for cancer treatment. - DDB2 is a promising target for cancer immunotherapy because it is highly expressed in cancer cells and is involved in DNA repair and cell cycle regulation.
