Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg\/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃\/-80℃. Our default final concentration of glycerol is 50%.

Core component of the UV-DDB complex (UV-damaged DNA-binding protein complex), a complex that recognizes UV-induced DNA damage and recruit proteins of the nucleotide excision repair pathway (the NER pathway) to initiate DNA repair. The UV-DDB complex preferentially binds to cyclobutane pyrimidine dimers (CPD), 6-4 photoproducts (6-4 PP), apurinic sites and short mismatches. Also functions as the substrate recognition module for the DCX (DDB2-CUL4-X-box) E3 ubiquitin-protein ligase complex DDB2-CUL4-ROC1 (also known as CUL4-DDB-ROC1 and CUL4-DDB-RBX1). The DDB2-CUL4-ROC1 complex may ubiquitinate histone H2A, histone H3 and histone H4 at sites of UV-induced DNA damage. The ubiquitination of histones may facilitate their removal from the nucleosome and promote subsequent DNA repair. The DDB2-CUL4-ROC1 complex also ubiquitinates XPC, which may enhance DNA-binding by XPC and promote NER. The DDB2-CUL4-ROC1 complex also ubiquitinates KAT7\/HBO1 in response to DNA damage, leading to its degradation:  recognizes KAT7\/HBO1 following phosphorylation by ATR.; [Isoform D1]:  Inhibits UV-damaged DNA repair.; [Isoform D2]:  Inhibits UV-damaged DNA repair.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eReference\u003c\/b\u003e: \"Human DDB2 splicing variants are dominant negative inhibitors of UV-damaged DNA repair.\"\nInoki T., Yamagami S., Inoki Y., Tsuru T., Hamamoto T., Kagawa Y., Mori T., Endo H.\nBiochem.
