DDB2

DDB2

A gene on chromosome 11p12-p11 that encodes a protein necessary for the repair of UV-light-damaged DNA, which is the small subunit of DNA damage-binding protein (a heterodimer composed of a large (DDB1) and a small subunit) that functions in nucleotide-excision repair.

Molecular pathology
DDB2 mutations have been tentatively linked xeroderma pigmentosum complementation group E (XPE).

The polymorphisms of multiple genes involved in NER pathways are associated with different prognostics of gastric cancer; for example, excision repair cross-complementing group 2 (ERCC2) and excision repair cross-complementing group 6 (ERCC6) are associated with poor prognostic, while ERCC1, ERCC5, and DDB2 predict longer overall survival (13).
Other mechanisms by which PEITC induces apoptosis (at 50 /M) include the increase of DDB2 (damaged DNA-binding protein 2) expression, as observed in colon cancer cells (HCT 116) in vitro and in vivo [186], as well as the activation of the extrinsic apoptotic pathway (death receptor-mediated apoptosis), as observed in oral and cervical cancer cells [187].

Among these genes, 9 [aprataxin (APTX), aprataxin and PNKP like factor (APLF), X-ray repair cross complementing 4 (XRCC4), BRCA1 interacting protein C-terminal helicase 1 (BRIP1), Fanconi anemia complementation group B (FANCB), Fanconi anemia complementation group M (FANCM), damage specific DNA binding protein 2 (DDB2), XPC complex subunit, DNA damage recognition and repair factor (XPC), and mutL homolog 3 (MLH3)] were over-expressed in CTC-MCC-41 cells and only 4 [DNA polymerase mu (POLM), RAD51 recombinase (RAD51), ERCC excision repair 1 (ERCC1), and tumor protein p53 binding protein 1 (TP53BP1)] in HT-29 cells.
A commercial Xeroderma Pigmentosum Next Generation Sequencing panel including the genes DDB2, ERCC2, ERCC3, ERCC4, ERCC5, POLH, XP-A, and XPC revealed a homozygous germline sequence variant designated c.547A>T in the XPC gene, which was confirmed by Sanger sequencing.
In order to obtain a thorough understanding on DNA repair mechanism on cell-TNA interaction, important genes, namely, RAD50, DDB2, XRCC5, XRCC6, ATM, THP0, ANGPTL6, and MRE11A, were further profiled at mRNA expression level on epithelial HT29 cells compared to control surfaces, namely, plastic, glass, and TiP (Figure 4(b)).
Several genes found to be consistently affected by radiation are part of the transformation related protein 53 [p53 (Trp53)] DNA damage response: cyclin-dependent kinase inhibitor lA (Cdkn 1a), growth arrest and DNA-damage-inducible 45 alpha (Gadd45a), transformed mouse 3T3 cell double minute 2 (Mdm2), ataxia telangiectasia mutated homolog (human) (Atm), and damage specific DNA binding protein 2 (Ddb2) (Gruel et al.
