Volume: 100 µg Purification: Protein A+G purification Form: liquid Purity: 95% as determined by SDS-PAGE Host: Mouse Clonality: monoclonal Clone ID: 3A0 Isotype: IgG2a Storage: PBS with 0.02% sodium azide and 50% glycerol pH 7.3,-20? for 12 months(Avoid repeated freeze / thaw cycles.) Background: Required for DNA repair. Binds to DDB2 to form the UV-damaged DNA-binding protein complex(the UV-DDB complex). The UV-DDB complex may recognize 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 appears to function as a component of numerous distinct DCX(DDB1-CUL4-X-box) E3 ubiquitin-protein ligase complexes which mediate the ubiquitination and subsequent proteasomal degradation of target proteins. The functional specificity of the DCX E3 ubiquitin-protein ligase complex is determined by the variable substrate recognition component recruited by DDB1. DCX(DDB2)(also known as DDB1-CUL4-ROC1, CUL4-DDB-ROC1 and CUL4-DDB-RBX1) 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. DCX(DDB2) also ubiquitinates XPC, which may enhance DNA-binding by XPC and promote NER. DCX(DTL) plays a role in PCNA-dependent polyubiquitination of CDT1 and MDM2-dependent ubiquitination of TP53 in response to radiation-induced DNA damage and during DNA replication. DCX(ERCC8)(the CSA complex) plays a role in transcription-coupled repair(TCR). May also play a role in ubiquitination of CDKN1B/p27kip when associated with CUL4 and SKP2.
