通用注释
亚单元:
Binds to at least four scaffolding proteins, MAPK8IP1/JIP-1, MAPK8IP2/JIP-2, MAPK8IP3/JIP-3/JSAP1 and SPAG9/MAPK8IP4/JIP-4. These proteins also bind other components of the JNK signaling pathway. Interacts with TP53, WWOX and JAMP. Interacts with NFATC4. Interacts (phosphorylated form) with NFE2; the interaction phosphorylates NFE2 in undifferentiated cells. Interacts with MECOM; regulates JNK signaling. Interacts with PIN1; this interaction mediates MAPK8 conformational changes leading to the binding of MAPK8 to its substrates (By similarity). Interacts with HSF1 (via D domain and preferentially with hyperphosphorylated form); this interaction occurs under both normal growth conditions and immediately upon heat shock (By similarity). Forms a complex with MAPK8IP1 and ARHGEF28. Interacts with STMN2, STMN3 and STMN4.
功能:
Serine/threonine-protein kinase involved in various processes such as cell proliferation, differentiation, migration, transformation and programmed cell death. Extracellular stimuli such as proinflammatory cytokines or physical stress stimulate the stress-activated protein kinase/c-Jun N-terminal kinase (SAP/JNK) signaling pathway. In this cascade, two dual specificity kinases MAP2K4/MKK4 and MAP2K7/MKK7 phosphorylate and activate MAPK8/JNK1. In turn, MAPK8/JNK1 phosphorylates a number of transcription factors, primarily components of AP-1 such as JUN, JDP2 and ATF2 and thus regulates AP-1 transcriptional activity. Phosphorylates the replication licensing factor CDT1, inhibiting the interaction between CDT1 and the histone H4 acetylase HBO1 to replication origins. Loss of this interaction abrogates the acetylation required for replication initiation. Promotes stressed cell apoptosis by phosphorylating key regulatory factors including p53/TP53 and Yes-associates protein YAP1. In T-cells, MAPK8 and MAPK9 are required for polarized differentiation of T-helper cells into Th1 cells. Contributes to the survival of erythroid cells by phosphorylating the antagonist of cell death BAD upon EPO stimulation. Mediates starvation-induced BCL2 phosphorylation, BCL2 dissociation from BECN1, and thus activation of autophagy. Phosphorylates STMN2 and hence regulates microtubule dynamics, controlling neurite elongation in cortical neurons. In the developing brain, through its cytoplasmic activity on STMN2, negatively regulates the rate of exit from multipolar stage and of radial migration from the ventricular zone (By similarity). Phosphorylates several other substrates including heat shock factor protein 4 (HSF4), the deacetylase SIRT1, ELK1, or the E3 ligase ITCH. Phosphorylates the CLOCK-ARNTL/BMAL1 heterodimer and plays a role in the regulation of the circadian clock (By similarity). Phosphorylates the heat shock transcription factor HSF1, suppressing HSF1-induced transcriptional activity.

大鼠促分裂原活化蛋白激酶8(Mapk8)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].
大鼠促分裂原活化蛋白激酶8(Mapk8)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].
怎样确定大鼠促分裂原活化蛋白激酶8(Mapk8)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].
大鼠促分裂原活化蛋白激酶8(Mapk8)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].
大鼠促分裂原活化蛋白激酶8(Mapk8)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].
大鼠促分裂原活化蛋白激酶8(Mapk8)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。
[7].
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].
大鼠促分裂原活化蛋白激酶8(Mapk8)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].
大鼠促分裂原活化蛋白激酶8(Mapk8)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。
