活性重组蛋白 Recombinant Human IL-11RA / IL1RAP / C3orf13 / IL-1 R3 / IL-1 RAcP Protein　重组蛋白

研究方向

IL-11RA 在基质细胞上高表达，包括成纤维细胞、平滑肌细胞、脂肪细胞和肝/胰腺星状细胞或周细胞，也在上皮/极化细胞上高表达，例如肝细胞、肺泡上皮细胞和肾小管上皮细胞。
人IL-11R α蛋白的氨基酸序列与小鼠和大鼠IL-11R α蛋白的同源性较低。
IL-11R α是IL-11的受体，是IL-11触发的信号机制-11 通过 IL-11R α 介导。IL-11R α可以结合IL-11，然后复合物吸引gp130导致信号转导。此外，IL11RA 已被证明可以激活 IL-11 介导的 gp130 信号传导，但不能激活可溶性 IL-11 受体的天然形式。IL-11 与 IL11RA 的结合触发异二聚化、酪氨酸磷酸化和 gp130 的激活。激活的 IL11RA–gp130 受体复合物进一步激活 Jak 酪氨酸激酶家族 JAK1、JAK2 和 TYK2。
IL-11R α 在体外也可充当 IL-11 激动剂。IL-11R α 诱导成骨祖细胞或其他间充质细胞的增殖和/或分化。

描述

Recombinant Human IL-1R3/IL-1RAcP/IL1RAP Protein is produced by Expi293 expression system. The target protein is expressed with sequence (Ser21-Glu359) of Human IL-1R3 fused with a His tag at the C-terminal.

储存

Store at -20℃. Store the lyophilized protein at -20℃ to -80℃ up to 1 year from the date of receipt.
After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ for up to 1 week.未开盖的干粉蛋白在 -20°C至-80°C可保存12个月；
复溶之后，蛋白溶液在-20°C及以下可保存3个月，在2-8℃可保存1周。

复溶

Centrifuge the tube before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid vortex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.收到重组蛋白产品之后请检查蛋白冻干粉末是否贴于瓶底，如果粉末浮起，开盖之前请先低温离心。将蛋白用说明书中指定的缓冲液复溶至0.1-0.5 mg/mL（请注意蛋白复溶浓度不能低于0.1 mg/mL），室温平衡5-10 min保证充分溶解，复溶过程中请不要剧烈涡旋及吹打蛋白溶液。如需长期储存，建议复溶时添加载体蛋白或者稳定剂（如0.1% BSA, 5% HSA, 10% FBS 或者 5% 海藻糖），同时将复溶后的蛋白溶液按照需求进行分装，储存于-20°C至-80°C，随取随用，避免反复冻融。

背景信息

IL-1 Receptor Accessory Protein (IL-1 RAcP), also known as IL-1 R3, is a ubiquitously expressed 70-90 kDa member of the Interleukin-1 receptor family of proteins. It serves as a non-ligand-binding component of the receptors for IL-1 alpha, IL-1 beta, IL-33, and IL-36. IL-1 R3 is a coreceptor for IL1RL2 in the IL-36 signaling system. IL-1 R3 is a coreceptor with IL1R1 in the IL-1 signaling system. Associates with IL1R1 bound to IL1B to form the high affinity interleukin-1 receptor complex which mediates interleukin-1-dependent activation of NF-kappa-B and other pathways.
