通用注释

亚单元:

Isoform 2 interacts with SIRT1. Isoform 2 interacts with PIK3R1 and PIK3R2; the interactions are direct and induce translocation of XBP1 isoform 2 into the nucleus and the unfolded protein response (UPR) XBP1-dependent target genes activation in a ER stress- and/or insulin-dependent but PI3K-independent manner. Isoform 2 interacts with FOXO1; the interaction is direct and leads to FOXO1 ubiquitination and degradation via the proteasome pathway in hepatocytes (By similarity). Isoform 1 interacts with HM13 (PubMed:25239945). Isoform 1 interacts with RNF139; the interaction induces ubiquitination and degradation of isoform 1 (PubMed:25239945). Isoform 1 interacts (via luminal domain) with DERL1; the interaction obviates the need for ectodomain shedding prior HM13/SPP-mediated XBP1 isoform 1 cleavage (PubMed:25239945). Isoform 1 interacts with isoform 2; the interaction sequesters isoform 2 from the nucleus and enhances isoform 2 degradation in the cytoplasm (PubMed:16461360, PubMed:25239945). Isoform 1 interacts with HDAC3 and AKT1; the interactions occur in endothelial cell (EC) under disturbed flow (PubMed:25190803). Isoform 1 interacts with the oncoprotein FOS (PubMed:1903538). Isoform 2 interacts with ATF6; the interaction occurs in a ER stress-dependent manner and is required for DNA binding to the unfolded protein response element (UPRE) (PubMed:17765680). Isoform 2 interacts with PIK3R1; the interaction is direct and induces translocation of XBP1 isoform 2 into the nucleus and the unfolded protein response (UPR) XBP1-dependent target genes activation in a ER stress- and/or insulin-dependent but PI3K-independent manner (PubMed:20348923).

功能:

Isoform 2: functions as a stress-inducible potent transcriptional activator during endoplasmic reticulum (ER) stress by inducing unfolded protein response (UPR) target genes via binding to the UPR element (UPRE). Up-regulates target genes encoding ER chaperones and ER-associated degradation (ERAD) components to enhance the capacity of productive folding and degradation mechanism, respectively, in order to maintain the homeostasis of the ER under ER stress (PubMed:11779464, PubMed:25239945). Plays a role in the production of immunoglobulins and interleukin-6 in the presence of stimuli required for plasma cell differentiation (By similarity). Induces phospholipid biosynthesis and ER expansion (PubMed:15466483). Contributes to the VEGF-induced endothelial cell (EC) growth and proliferation in a Akt/GSK-dependent and/or -independent signaling pathway, respectively, leading to beta-catenin nuclear translocation and E2F2 gene expression (PubMed:23529610). Promotes umbilical vein EC apoptosis and atherosclerotisis development in a caspase-dependent signaling pathway, and contributes to VEGF-induced EC proliferation and angiogenesis in adult tissues under ischemic conditions (PubMed:19416856, PubMed:23529610). Involved in the regulation of endostatin-induced autophagy in EC through BECN1 transcriptional activation (PubMed:23184933). Plays a role as an oncogene by promoting tumor progression: stimulates zinc finger protein SNAI1 transcription to induce epithelial-to-mesenchymal (EMT) transition, cell migration and invasion of breast cancer cells (PubMed:25280941). Involved in adipocyte differentiation by regulating lipogenic gene expression during lactation. Plays a role in the survival of both dopaminergic neurons of the substantia nigra pars compacta (SNpc), by maintaining protein homeostasis and of myeloma cells. Increases insulin sensitivity in the liver as a response to a high carbohydrate diet, resulting in improved glucose tolerance. Improves also glucose homeostasis in an ER stress- and/or insulin-independent manner through both binding and proteasome-induced degradation of the transcription factor FOXO1, hence resulting in suppression of gluconeogenic genes expression and in a reduction of blood glucose levels. Controls the induction of de novo fatty acid synthesis in hepatocytes by regulating the expression of a subset of lipogenic genes in an ER stress- and UPR-independent manner (By similarity). Associates preferentially to the HDAC3 gene promoter region in a disturbed flow-dependent manner (PubMed:25190803). Binds to the BECN1 gene promoter region (PubMed:23184933). Binds to the CDH5/VE-cadherin gene promoter region (PubMed:19416856). Binds to the ER stress response element (ERSE) upon ER stress (PubMed:11779464). Binds to the 5'-CCACG-3' motif in the PPARG promoter.

人X-盒结合蛋白1(XBP1)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。

如何分析人X-盒结合蛋白1(XBP1)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。
