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.
