| - | [[Category: | + | [https://www.uniprot.org/uniprot/DDB1_HUMAN DDB1_HUMAN] 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.<ref>PMID:12732143</ref> <ref>PMID:15448697</ref> <ref>PMID:14739464</ref> <ref>PMID:15882621</ref> <ref>PMID:16260596</ref> <ref>PMID:16482215</ref> <ref>PMID:17079684</ref> <ref>PMID:16407242</ref> <ref>PMID:16407252</ref> <ref>PMID:16678110</ref> <ref>PMID:16940174</ref> <ref>PMID:17041588</ref> <ref>PMID:16473935</ref> <ref>PMID:18593899</ref> <ref>PMID:18381890</ref> <ref>PMID:18332868</ref> |
