亚单元:
Monomer and homooligomer; homooligomerization via the interdomain linker inactivates the chaperone activity and acts as a storage of HSPA5/BiP molecules. Interacts with DNAJC1 (via J domain). Component of an EIF2 complex at least composed of CELF1/CUGBP1, CALR, CALR3, EIF2S1, EIF2S2, HSP90B1 and HSPA5. Part of a large chaperone multiprotein complex comprising DNAJB11, HSP90B1, HSPA5, HYOU, PDIA2, PDIA4, PDIA6, PPIB, SDF2L1, UGT1A1 and very small amounts of ERP29, but not, or at very low levels, CALR nor CANX. Interacts with TMEM132A and TRIM21. May form a complex with ERLEC1, OS9, SEL1L and SYVN1. Interacts with DNAJC10. Interacts with DNAJB9/ERdj4; leading to recruit HSPA5/BiP to ERN1/IRE1. Interacts with ERN1/IRE1; interaction takes place following interaction with DNAJB9/ERdj4 and leads to inactivate ERN1/IRE1. Interacts with MX1. Interacts with METTL23. Interacts with CEMIP; the interaction induces calcium leakage from the endoplasmic reticulum and cell migration. Interacts with PCSK4 form; the interaction takes place in the endoplasmic reticulum. Interacts with CIPC. Interacts with CCDC88B (via C-terminus); the interaction opposes ERN1-mediated JNK activation, protecting against apoptosis. Interacts with INPP5K; necessary for INPP5K localization at the endoplasmic reticulum. Interacts with MANF; the interaction is direct. Interacts with LOXL2; leading to activate the ERN1/IRE1-XBP1 pathway of the unfolded protein response. Interacts with CLU under stressed condition; interaction increases CLU protein stability; facilitates its retrotranslocation and redistribution to the mitochondria; cooperatively suppress stress-induced apoptosis by stabilizing mitochondrial membrane integrity (By similarity). Interacts with CCDC47 (By similarity).
功能:
Endoplasmic reticulum chaperone that plays a key role in protein folding and quality control in the endoplasmic reticulum lumen (By similarity). Involved in the correct folding of proteins and degradation of misfolded proteins via its interaction with DNAJC10/ERdj5, probably to facilitate the release of DNAJC10/ERdj5 from its substrate (By similarity). Acts as a key repressor of the ERN1/IRE1-mediated unfolded protein response (UPR). In the unstressed endoplasmic reticulum, recruited by DNAJB9/ERdj4 to the luminal region of ERN1/IRE1, leading to disrupt the dimerization of ERN1/IRE1, thereby inactivating ERN1/IRE1. Accumulation of misfolded protein in the endoplasmic reticulum causes release of HSPA5/BiP from ERN1/IRE1, allowing homodimerization and subsequent activation of ERN1/IRE1 (By similarity). Plays an auxiliary role in post-translational transport of small presecretory proteins across endoplasmic reticulum (ER). May function as an allosteric modulator for SEC61 channel-forming translocon complex, likely cooperating with SEC62 to enable the productive insertion of these precursors into SEC61 channel. Appears to specifically regulate translocation of precursors having inhibitory residues in their mature region that weaken channel gating.

牛78kDa葡萄糖调节蛋白(HSPA5)重组蛋白是否是无菌的?
蛋白试剂瓶和蛋白保存液是经过高压灭菌的,但也不能保证蛋白是完全无菌的。如果要求蛋白是无菌的,可以用0.2微米的滤器对蛋白进行过滤。
[2].
牛78kDa葡萄糖调节蛋白(HSPA5)重组蛋白的保存缓冲液是什么?
纯化后的蛋白保存在PBS(58mM Na2HPO4, 17mM NaH2PO4, 68mM NaCl, pH7.4)里,并往里面加入500mM咪唑和10%甘油。
[3].
怎样确定牛78kDa葡萄糖调节蛋白(HSPA5)重组蛋白的浓度?
蛋白浓度的确定没有一个统一的标准,这主要取决于蛋白的氨基酸序列。伊艾博是根据不同测试的组合来测定蛋白浓度。考马斯亮蓝法、BCA法、氨基酸序列和氨基酸全序列分析法等都用来测定蛋白浓度。
[4].
牛78kDa葡萄糖调节蛋白(HSPA5)重组蛋白蛋白保存条件是怎样的?
蛋白应保存在 -20℃或 -80℃条件下,为了避免反复冻融,可以将蛋白分装成小份保存。
[5].
牛78kDa葡萄糖调节蛋白(HSPA5)重组蛋白是否可以用于活体实验?
重组蛋白没有用于任何的活体实验,因此蛋白的活性和半衰期是不确定的。
[6].
牛78kDa葡萄糖调节蛋白(HSPA5)重组蛋白的保质期是多久?
在适当的保存条件下,从购买之日起蛋白可以稳定保存6-12个月。适当的保存条件是:蛋白保存在-20°C o或 -80℃,保证蛋白的保存浓度高于0.1mg/ml,限制蛋白反复冻融的次数。我们公司常规的质量检测保证所有产品在销售时都有可接受的生物活性。但是我们不能控制终端用户蛋白的保存条件。如果产品在有效期内出现问题,请联系我们的技术支持。

你们蛋白和抗体的报价是怎么样的?
我们将根据你需要的蛋白和抗体的大小进行报价。
[8].
牛78kDa葡萄糖调节蛋白(HSPA5)重组蛋白是否能够提供蛋白片段?
我们现有的人的蛋白的序列可以有很多。你可以选择你感兴趣的靶向部分,我们将会按您的需求提供蛋白和抗体。
[9].
牛78kDa葡萄糖调节蛋白(HSPA5)重组蛋白的货期或发货时间一般是多长?
具体指标的货期需要确定。最快一周,最长可能一个月。
