Component of the UV-DDB complex which includes DDB1 and DDB2; the heterodimer dimerizes to give rise to a heterotetramer when bound to damaged DNA. The UV-DDB complex interacts with monoubiquitinated histone H2A and binds to XPC via the DDB2 subunit. Component of numerous DCX (DDB1-CUL4-X-box) E3 ubiquitin-protein ligase complexes which consist of a core of DDB1, CUL4A or CUL4B and RBX1. DDB1 may recruit specific substrate targeting subunits to the DCX complex. These substrate targeting subunits are generally known as DCAF (DDB1- and CUL4-associated factor) or CDW (CUL4-DDB1-associated WD40-repeat) proteins. Interacts with AMBRA1, ATG16L1, BTRC, CRBN, DCAF1, DCAF4, DCAF5, DCAF6, DCAF7, DCAF8, DCAF9, DCAF10, DCAF11, DCAF12, DCAF15, DCAF16, DCAF17, DDA1, DET1, DTL, ERCC8, FBXW5, FBXW8, GRWD1, KATNB1, NLE1, NUP43, PAFAH1B1, PHIP, PWP1, RBBP4, RBBP5, RBBP7, RFWD2, SNRNP40, VPRBP, WDR5, WDR5B, WDR12, WDR26, WDR39, WDR42, WDR53, WDR59, WDR61, WSB1, WSB2, LRWD1 and WDTC1. DCX complexes may associate with the COP9 signalosome, and this inhibits the E3 ubiquitin-protein ligase activity of the complex. Interacts with NF2, TSC1 and TSC2. Interacts with AGO1 and AGO2. Associates with the E3 ligase complex containing DYRK2, EDD/UBR5, DDB1 and VPRBP proteins (EDVP complex). Interacts directly with DYRK2 (By similarity). Interacts with TRPC4AP.
功能:
Required for DNA repair. 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.

小鼠DNA损伤结合蛋白(Ddb1)ELISA试剂盒原理?
双抗体夹心法:用纯化的抗体包被微孔板,制成固相抗体,往包被有固相抗体的微孔中依次加入标准品或受检样本、生物素化抗体、HRP标记的亲和素,经过彻底洗涤后用底物TMB显色。用酶标仪在450nm波长下测定吸光度(OD值),计算样本浓度。
竞争法:用纯化的抗体包被微孔板,制成固相抗体,往包被有固相抗体的微孔中依次加入标准品或受检样本和生物素标记的目标分析物,受检标本中抗原与生物素标记抗原竞争结合有限的抗体。再加入HRP标记的亲和素,经过彻底洗涤后用底物TMB显色。用酶标仪在450nm波长下测定吸光度(OD值),计算样本浓度。

小鼠DNA损伤结合蛋白(Ddb1)ELISA试剂盒中需要使用的样品量是多少?
夹心法100μL/孔,竞争法50μL/孔。如样本浓度过高时,应对样本进行稀释,以使稀释后的样本符合试剂盒的检测范围,计算时再乘以相应的稀释倍数。
[6].
如何分析小鼠DNA损伤结合蛋白(Ddb1)ELISA试剂盒数据?
建议标准曲线,并计算样本浓度。对于elisa的曲线拟合,一般建议采用4参数曲线拟合,4参数曲线拟合通常更适合免疫分析。推荐使用专业软件进行曲线拟合,例如curve expert 1.3。根据样本的OD值由标曲查出相应的浓度,再乘以稀释倍数;或用标准物的浓度与OD值计算出标曲的回归方程式,将样本的OD值代入方程式,计算出样本浓度,再乘以稀释倍数,即为样本的实际浓度。以下链接是curve expert 1.3软件拟合曲线的方法。
