通用注释

亚单元:

Monomer. Heterotrimer; with a C-terminally phosphorylated R-SMAD molecule and to form the transcriptionally active SMAD2/3-SMAD4 complex. Found in a ternary complex composed of SMAD4, STK11/LKB1 and STK11IP. Interacts with ATF2, COPS5, DACH1, MSG1, SKI, STK11/LKB1, STK11IP and TRIM33. Found in a complex with SMAD1 and YY1. Associates with ZNF423 or ZNF521 in response to BMP2 leading to activate transcription of BMP target genes. Interacts with USP9X. Interacts with RBPMS. Interacts with WWTR1 (via coiled-coil domain). Interacts with CITED1 and CITED2. Interacts with PDPK1 (via PH domain). Interacts with VPS39; this interaction affects heterodimer formation with SMAD3, but not with SMAD2, and leads to inhibition of SMAD3-dependent transcription activation. Interactions with VPS39 and SMAD2 may be mutually exclusive. Interacts with ZC3H3. Interacts (via MH2 domain) with ZNF451 (via N-terminal zinc-finger domains) (By similarity). Identified in a complex that contains at least ZNF451, SMAD2, SMAD3 and SMAD4. Interacts weakly with ZNF8. Interacts with NUP93 and IPO7; translocates SMAD4 to the nucleus through the NPC upon BMP7 stimulation resulting in activation of SMAD4 signaling (By similarity). Interacts with CREB3L1, the interaction takes place upon TGFB1 induction and SMAD4 acts as CREB3L1 coactivator to induce the expression of genes involved in the assembly of collagen extracellular matrix (By similarity). Interacts with DLX1.

功能:

Common SMAD (co-SMAD) is the coactivator and mediator of signal transduction by TGF-beta (transforming growth factor). Component of the heterotrimeric SMAD2/SMAD3-SMAD4 complex that forms in the nucleus and is required for the TGF-mediated signaling. Promotes binding of the SMAD2/SMAD4/FAST-1 complex to DNA and provides an activation function required for SMAD1 or SMAD2 to stimulate transcription. Component of the multimeric SMAD3/SMAD4/JUN/FOS complex which forms at the AP1 promoter site; required for synergistic transcriptional activity in response to TGF-beta. Acts synergistically with SMAD1 and YY1 in bone morphogenetic protein (BMP)-mediated cardiac-specific gene expression. Binds to SMAD binding elements (SBEs) (5'-GTCT/AGAC-3') within BMP response element (BMPRE) of cardiac activating regions. May act as a tumor suppressor. Positively regulates PDPK1 kinase activity by stimulating its dissociation from the 14-3-3 protein YWHAQ which acts as a negative regulator (By similarity). In muscle physiology, plays a central role in the balance between atrophy and hypertrophy. When recruited by MSTN, promotes atrophy response via phosphorylated SMAD2/4. MSTN decrease causes SMAD4 release and subsequent recruitment by the BMP pathway to promote hypertrophy via phosphorylated SMAD1/5/8.

亚细胞位置:

Cytoplasm Nucleus In the cytoplasm in the absence of ligand. Migration to the nucleus when complexed with R-SMAD. PDPK1 prevents its nuclear translocation.

猪母亲DDP同源物4(SMAD4)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].

猪母亲DDP同源物4(SMAD4)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].

怎样确定猪母亲DDP同源物4(SMAD4)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].

猪母亲DDP同源物4(SMAD4)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].

猪母亲DDP同源物4(SMAD4)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].

猪母亲DDP同源物4(SMAD4)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].

猪母亲DDP同源物4(SMAD4)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].

猪母亲DDP同源物4(SMAD4)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。
