Summary: Predicted to contribute to damaged DNA binding activity and ubiquitin-protein transferase activity. Involved in DNA damage response and cellular response to UV. Acts upstream of or within pyrimidine dimer repair. Part of Cul4A-RING E3 ubiquitin ligase complex. Used to study xeroderma pigmentosum group E. Human ortholog(s) of this gene implicated in xeroderma pigmentosum and xeroderma pigmentosum group E. Orthologous to human DDB2 (damage specific DNA binding protein 2).

DDB2 plays a critical role in suppressing development of colon cancer at early stage by regulating Wnt signaling. Mice genetically deficient in DDB2 exhibited increased susceptibility to colon tumor development in a manner associated with higher abundance of the Wnt receptor-expressing cells and greater activation of the downstream Wnt pathway.

UVRAG is a regulator of CRL4(DDB2)-mediated nucleotide excision repair and its expression levels may influence melanoma predisposition.
Title: Autophagic UVRAG Promotes UV-Induced Photolesion Repair by Activation of the CRL4(DDB2) E3 Ligase.
Results indicate a transcriptional regulatory pathway of DDB2 that is directly linked to the mechanisms that suppress metastasis of colon cancer.
Title: DDB2 suppresses epithelial-to-mesenchymal transition in colon cancer.
Data indicate that poly(ADP-ribose) polymerase-1 (PARP-1)collaborates with DNA-binding protein 2 (DDB2) to increase the efficiency of the lesion recognition step of global genomic subpathway of NER (GG-NER).
Title: Role of poly(ADP-ribose) polymerase-1 in the removal of UV-induced DNA lesions by nucleotide excision repair.
the anti-proliferative and the pro-senescence pathways of DDB2 and p21 are critical protection mechanisms against skin malignancies.
Title: p21 cooperates with DDB2 protein in suppression of ultraviolet ray-induced skin malignancies.
mouse keratinocytes express sufficient levels of UV-DDB for efficient repair of photolesions and efficient protection against Ultraviolet rays (UV)-induced skin cancer at physiological relevant ultraviolet rays exposure.

results provide evidence for a new regulatory loop involving the NER protein DDB2, Mdm2, and p21(Waf1/Cip1) that is critical in deciding cell fate (apoptosis or arrest) upon DNA damage.
Title: DDB2 decides cell fate following DNA damage.
provide genetic evidence linking the regulation of p21(Waf1/Cip1) to the nucleotide excision repair activity of DDB2
Title: The xeroderma pigmentosum group E gene product DDB2 activates nucleotide excision repair by regulating the level of p21Waf1/Cip1.
results indicate the bulk of DDB2 interacts with lesions independent of XPC & there is little interaction between the two recognition proteins on damaged DNA; propose a scenario in which DDB2 prepares UV-damaged chromatin for assembly of the NER complex
Title: Dynamic in vivo interaction of DDB2 E3 ubiquitin ligase with UV-damaged DNA is independent of damage-recognition protein XPC.
Ddb2 heterozygosity can facilitate tumor development as a haploinsufficient tumor suppressor
Title: Ddb2 is a haploinsufficient tumor suppressor and controls spontaneous germ cell apoptosis.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
