CC -!- FUNCTION: Protein, which is both involved in DNA repair and protein
CC ubiquitination, as part of the UV-DDB complex and DCX (DDB1-CUL4-X-box)
CC complexes, respectively. Core component of the UV-DDB complex (UV-
CC damaged DNA-binding protein complex), a complex that recognizes UV-
CC induced DNA damage and recruit proteins of the nucleotide excision
CC repair pathway (the NER pathway) to initiate DNA repair. The UV-DDB
CC complex preferentially binds to cyclobutane pyrimidine dimers (CPD), 6-
CC 4 photoproducts (6-4 PP), apurinic sites and short mismatches. Also
CC functions as a component of numerous distinct DCX (DDB1-CUL4-X-box) E3
CC ubiquitin-protein ligase complexes which mediate the ubiquitination and
CC subsequent proteasomal degradation of target proteins. The functional
CC specificity of the DCX E3 ubiquitin-protein ligase complex is
CC determined by the variable substrate recognition component recruited by
CC DDB1. DCX(DDB2) (also known as DDB1-CUL4-ROC1, CUL4-DDB-ROC1 and CUL4-
CC DDB-RBX1) may ubiquitinate histone H2A, histone H3 and histone H4 at
CC sites of UV-induced DNA damage. The ubiquitination of histones may
CC facilitate their removal from the nucleosome and promote subsequent DNA
CC repair. DCX(DDB2) also ubiquitinates XPC, which may enhance DNA-binding
CC by XPC and promote NER. DCX(DTL) plays a role in PCNA-dependent
CC polyubiquitination of CDT1 and MDM2-dependent ubiquitination of TP53 in
CC response to radiation-induced DNA damage and during DNA replication.
CC DCX(ERCC8) (the CSA complex) plays a role in transcription-coupled
CC repair (TCR). The DDB1-CUL4A-DTL E3 ligase complex regulates the
CC circadian clock function by mediating the ubiquitination and
CC degradation of CRY1 (By similarity). DDB1-mediated CRY1 degradation
CC promotes FOXO1 protein stability and FOXO1-mediated gluconeogenesis in
CC the liver (By similarity). {ECO:0000250|UniProtKB:Q16531,
CC ECO:0000250|UniProtKB:Q3U1J4}.
CC -!- PATHWAY: Protein modification; protein ubiquitination.
CC {ECO:0000250|UniProtKB:Q16531}.
CC -!- SUBUNIT: Component of the UV-DDB complex which includes DDB1 and DDB2;
CC the heterodimer dimerizes to give rise to a heterotetramer when bound
CC to damaged DNA. The UV-DDB complex interacts with monoubiquitinated
CC histone H2A and binds to XPC via the DDB2 subunit. Component of
CC numerous DCX (DDB1-CUL4-X-box) E3 ubiquitin-protein ligase complexes
CC which consist of a core of DDB1, CUL4A or CUL4B and RBX1. DDB1 may
CC recruit specific substrate targeting subunits to the DCX complex. These
CC substrate targeting subunits are generally known as DCAF (DDB1- and
CC CUL4-associated factor) or CDW (CUL4-DDB1-associated WD40-repeat)
CC proteins. Interacts with AMBRA1, ATG16L1, BTRC, CRBN, DCAF1, DCAF4,
CC DCAF5, DCAF6, DCAF7, DCAF8, DCAF9, DCAF10, DCAF11, DCAF12, DCAF15,
CC DCAF16, DCAF17, DDA1, DET1, DTL, ERCC8, FBXW5, FBXW8, GRWD1, KATNB1,
CC NLE1, NUP43, PAFAH1B1, PHIP, PWP1, RBBP4, RBBP5, RBBP7, COP1, SNRNP40,
CC DCAF1, WDR5, WDR5B, WDR12, WDR26, WDR39, WDR42, WDR53, WDR59, WDR61,
CC WSB1, WSB2, LRWD1 and WDTC1. DCX complexes may associate with the COP9
CC signalosome, and this inhibits the E3 ubiquitin-protein ligase activity
CC of the complex. Interacts with NF2, TSC1 and TSC2. Interacts with AGO1
CC and AGO2. Associates with the E3 ligase complex containing DYRK2,
CC EDD/UBR5, DDB1 and DCAF1 proteins (EDVP complex). Interacts directly
CC with DYRK2. DCX(DTL) complex interacts with FBXO11; does not
CC ubiquitinate and degradate FBXO11. Interacts with TRPC4AP (By
CC similarity). Interacts with CRY1 and CRY2 (By similarity). The DDB1-
CC CUL4A complex interacts with CRY1 (By similarity). May also interact
CC with DCUN1D1, DCUN1D2, DCUN1D3 and DCUN1D5 (By similarity).
CC {ECO:0000250|UniProtKB:Q16531, ECO:0000250|UniProtKB:Q3U1J4}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:Q16531}. Nucleus
CC {ECO:0000250|UniProtKB:Q16531}. Note=Primarily cytoplasmic.
CC Translocates to the nucleus following UV irradiation and subsequently
CC accumulates at sites of DNA damage. {ECO:0000250|UniProtKB:Q16531}.
CC -!- DOMAIN: The core of the protein consists of three WD40 beta-propeller
CC domains. {ECO:0000250|UniProtKB:Q16531}.
CC -!- PTM: Phosphorylated by ABL1. {ECO:0000250|UniProtKB:Q3U1J4}.
CC -!- PTM: Ubiquitinated by CUL4A. Subsequently degraded by ubiquitin-
CC dependent proteolysis. {ECO:0000250|UniProtKB:Q16531}.
CC -!- PTM: Acetylated, promoting interaction with CUL4 (CUL4A or CUL4B) and
CC subsequent formation of DCX (DDB1-CUL4-X-box) E3 ubiquitin-protein
CC ligase complexes. Deacetylation by SIRT7 impairs the interaction with
CC CUL4 (CUL4A or CUL4B) and formation of DCX (DDB1-CUL4-X-box) E3
CC ubiquitin-protein ligase complexes. {ECO:0000250|UniProtKB:Q16531}.
CC -!- SIMILARITY: Belongs to the DDB1 family. {ECO:0000305}.
