功能
Acts as an E3 ubiquitin-protein ligase which accepts ubiquitin from an E2 ubiquitin-conjugating enzyme in the form of a thioester and then directly transfers the ubiquitin to targeted substrates. It catalyzes 'Lys-29'-, 'Lys-48'- and 'Lys-63'-linked ubiquitin conjugation. It is involved in the control of inflammatory signaling pathways. Is an essential component of a ubiquitin-editing protein complex, comprising also TNFAIP3, TAX1BP1 and RNF11, that ensures the transient nature of inflammatory signaling pathways. Promotes the association of the complex after TNF stimulation. Once the complex is formed, TNFAIP3 deubiquitinates 'Lys-63' polyubiquitin chains on RIPK1 and catalyzes the formation of 'Lys-48'-polyubiquitin chains. This leads to RIPK1 proteasomal degradation and consequently termination of the TNF- or LPS-mediated activation of NFKB1. Ubiquitinates RIPK2 by 'Lys-63'-linked conjugation and influences NOD2-dependent signal transduction pathways. Regulates the transcriptional activity of several transcription factors, and probably plays an important role in the regulation of immune response. Ubiquitinates NFE2 by 'Lys-63' linkages and is implicated in the control of the development of hematopoietic lineages. Critical regulator of T-helper (TH2) cytokine development through its ability to induce JUNB ubiquitination and degradation (By similarity). Ubiquitinates SNX9. Ubiquitinates CXCR4 and HGS/HRS and regulates sorting of CXCR4 to the degradative pathway. It is involved in the negative regulation of MAVS-dependent cellular antiviral responses. Ubiquitinates MAVS through 'Lys-48'-linked conjugation resulting in MAVS proteasomal degradation. Ubiquitinates MAP3K7 through 'Lys-48'-linked conjugation (By similarity). Involved in the regulation of apoptosis and reactive oxygen species levels through the ubiquitination and proteasomal degradation of TXNIP. Mediates the antiapoptotic activity of epidermal growth factor through the ubiquitination and proteasomal degradation of p15 BID. Targets DTX1 for lysosomal degradation and controls NOTCH1 degradation, in the absence of ligand, through 'Lys-29'-linked polyubiquitination. Ubiquitinates BRAT1 and this ubiquitination is enhanced in the presence of NDFIP1 (PubMed:25631046).风险提示：丁香通仅作为第三方平台，为商家信息发布提供平台空间。用户咨询产品时请注意保护个人信息及财产安全，合理判断，谨慎选购商品，商家和用户对交易行为负责。对于医疗器械类产品，请先查证核实企业经营资质和医疗器械产品注册证情况。
文献和实验：分别是竞争性蛋白质结合分析法[3]、放射性免疫分析法[4]和薄层色谱法[5]。在80年代，放射性免疫分析法得到了广泛的应用和改进，由于这种方法采用放射性核素标记，应用范围受到一定限制，为了进一步提高检测的灵敏度和操作的安全性，进入90年代又陆续发明了各种酶标记法和化学发光法的竞争性ELISA检测试剂盒，这一类检测方法的根本原理都是基于抗体抗原的免疫反应，所有这些试剂盒中采用的抗体全部是兔抗血清或者是经过特异亲和提纯之后的抗cAMP或cGMP的兔多抗，毫无疑问，兔多抗在约四十年的cAMP，cGMP定量
单抗主要是鼠单抗、兔单抗，多抗主要是兔多抗、山羊多抗等，其他种属来源抗体较少。不建议纠结于单抗好还是多抗好，能做出实验的抗体就是好抗体。 在选择上一般建议实验种属和抗体种属亲缘性越远越好，不宜同源。抗体不同种属会要影响接下来二抗的选配。特别是在免疫荧光双标实验中，需要在区别于实验种属的基础上，区分开两个指标的抗体种属来源，以便于二抗区别识别。 3. 关于性价比的选择 抗体的品质高低最终还是需要通过实验结果来呈现的，但是在选择抗体之前我们并无法准确判断抗体的效果
