通用注释
亚单元:
Binds DNA as a dimer and can form a homodimer in the absence of DNA. Can form a heterodimer with JUN. Heterodimerization is essential for its transcriptional activity. Interacts with SMAD3 and SMAD4. Binds through its N-terminal region to UTF1 which acts as a coactivator of ATF2 transcriptional activity. Interacts with the HK1/VDAC1 complex. Interacts with NBN, MRE11, XPO1, KAT5 and CUL3.
功能:
Transcriptional activator which regulates the transcription of various genes, including those involved in anti-apoptosis, cell growth, and DNA damage response. Dependent on its binding partner, binds to CRE (cAMP response element) consensus sequences (5'-TGACGTCA-3') or to AP-1 (activator protein 1) consensus sequences (5'-TGACTCA-3'). In the nucleus, contributes to global transcription and the DNA damage response, in addition to specific transcriptional activities that are related to cell development, proliferation and death. In the cytoplasm, interacts with and perturbs HK1- and VDAC1-containing complexes at the mitochondrial outer membrane, thereby impairing mitochondrial membrane potential, inducing mitochondrial leakage and promoting cell death. The phosphorylated form (mediated by ATM) plays a role in the DNA damage response and is involved in the ionizing radiation (IR)-induced S phase checkpoint control and in the recruitment of the MRN complex into the IR-induced foci (IRIF). Exhibits histone acetyltransferase (HAT) activity which specifically acetylates histones H2B and H4 in vitro. In concert with CUL3 and RBX1, promotes the degradation of KAT5 thereby attenuating its ability to acetylate and activate ATM. Can elicit oncogenic or tumor suppressor activities depending on the tissue or cell type.
亚细胞位置:

Mitochondrion outer membrane
Shuttles between the cytoplasm and the nucleus and heterodimerization with JUN is essential for the nuclear localization. Localization to the cytoplasm is observed under conditions of cellular stress and in disease states. Localizes at the mitochondrial outer membrane in response to genotoxic stress. Phosphorylation at Thr-52 is required for its nuclear localization and negatively regulates its mitochondrial localization. Co-localizes with the MRN complex in the IR-induced foci (IRIF).

人环AMP依赖性转录因子ATF-2(ATF2)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。

人环AMP依赖性转录因子ATF-2(ATF2)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].
如何分析人环AMP依赖性转录因子ATF-2(ATF2)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。
