In conjunction with CUL4A and ROC-1, the UV-DDB complex forms an E3 ubiquitin ligase that recognizes a broad spectrum of DNA lesions such as cyclobutane pyrimidine dimers, 6-4 photoproducts, apurinic sites and short mismatches. The complex polyubiquitinates components of the nucleotide excision repair pathway (4-6). Loss of DDB activity has been identified in a subset of xeroderma pigmentosum complementation group E (XP-E) patients and has been linked to the deficient repair of cyclobutane pyrimidine dimers in cells derived from these patients (7-10). DDB-1 is a relatively abundant protein that is vital for normal cell function and is evolutionarily conserved in mammals, insects, worms and plants. Unlike DDB-2, lesions in DDB-1 have yet to be indentified in XP-E patients. In association with ROC-1 and CUL4A, DDB-1 functions to recruit substrate-specific targeting subunits, generally known as DCAFs or CDWs, to CUL4-RING E3 ubiquitin-protein ligase complexes (11,12). Ubiquitination of histone H2A, histone H3 and histone H4 at sites of UV-induced DNA damage by the DDB1-DDB2-CUL4A-ROC1 E3 ubiquitin-protein ligase complex may facilitate their removal from the nucleosome in order to promote DNA repair (13-15). DDB-1, in association with other CUL4-based E3 ligase complexes, has also been found to be a regulator of mTOR signaling (16,17).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\ndamage specific DNA binding protein 1; damage-specific DNA binding protein 1, 127kDa; Damage-specific DNA-binding protein 1; DDB p127 subunit; DDB1; DDBa; DNA damage-binding protein 1; DNA damage-binding protein a; HBV X-associated protein 1; UV-damaged DNA-binding factor; UV-damaged DNA-binding protein 1; UV-DDB 1; UV-DDB1; XAP-1; XAP1; Xeroderma pigmentosum group E-complementing protein; XPCe; XPE; XPE-BF; XPE-binding factor\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M R Mk\nSENSITIVITY: Endogenous\nMW (kDa): 127\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46799865839785,"sku":"6998S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-6998s","provider":"Iright","version":"1.0","type":"link"}
