Monomer; in the absence of TGF-beta. Homooligomer; in the presence of TGF-beta. Heterotrimer; forms a heterotrimer in the presence of TGF-beta consisting of two molecules of C-terminally phosphorylated SMAD2 or SMAD3 and one of SMAD4 to form the transcriptionally active SMAD2/SMAD3-SMAD4 complex. Interacts with TGFBR1. Interacts (via the MH2 domain) with ZFYVE9. Interacts with HDAC1, VDR, TGIF and TGIF2, RUNX3, CREBBP, SKOR1, SKOR2, SNON, ATF2, SMURF2 and SNW1. Interacts with DACH1; the interaction inhibits the TGF-beta signaling. Part of a complex consisting of AIP1, ACVR2A, ACVR1B and SMAD3. Forms a complex with SMAD2 and TRIM33 upon addition of TGF-beta. Found in a complex with SMAD3, RAN and XPO4. Interacts in the complex directly with XPO4. Interacts (via the MH2 domain) with LEMD3; the interaction represses SMAD3 transcriptional activity through preventing the formation of the heteromeric complex with SMAD4 and translocation to the nucleus. Interacts with RBPMS. Interacts (via MH2 domain) with MECOM. Interacts with WWTR1 (via its coiled-coil domain). Interacts (via the linker region) with EP300 (C-terminal); the interaction promotes SMAD3 acetylation and is enhanced by TGF-beta phosphorylation in the C-terminal of SMAD3. This interaction can be blocked by competitive binding of adenovirus oncoprotein E1A to the same C-terminal site on EP300, which then results in partially inhibited SMAD3/SMAD4 transcriptional activity. Interacts with SKI; the interaction represses SMAD3 transcriptional activity. Component of the multimeric complex SMAD3/SMAD4/JUN/FOS which forms at the AP1 promoter site; required for synergistic transcriptional activity in response to TGF-beta. Interacts (via an N-terminal domain) with JUN (via its basic DNA binding and leucine zipper domains); this interaction is essential for DNA binding and cooperative transcriptional activity in response to TGF-beta. Interacts with PPM1A; the interaction dephosphorylates SMAD3 in the C-terminal SXS motif leading to disruption of the SMAD2/3-SMAD4 complex, nuclear export and termination of TGF-beta signaling. Interacts (dephosphorylated form via the MH1 and MH2 domains) with RANBP3 (via its C-terminal R domain); the interaction results in the export of dephosphorylated SMAD3 out of the nucleus and termination of the TGF-beta signaling. Interacts with AIP1, PML, TGFB1I1, TTRAP, FOXL2, PRDM16, HGS and WWP1. Interacts with NEDD4L; the interaction requires TGF-beta stimulation. Interacts with MEN1. Interacts (via MH2 domain) with CITED2 (via C-terminus). Interaction with CSNK1G2. Interacts with PDPK1 (via PH domain). Interacts with DAB2; the interactions are enhanced upon TGF-beta stimulation. Interacts with USP15. Interacts with PPP5C; the interaction decreases SMAD3 phosphorylation and protein levels. Interacts with LDLRAD4 (via the SMAD interaction motif). Interacts with PMEPA1. Interacts with ZC3H3. Interacts with ZFHX3. Interacts with ZNF451. Identified in a complex that contains at least ZNF451, SMAD2, SMAD3 and SMAD4. Interacts weakly with ZNF8. Interacts (when phosphorylated) with RNF111; RNF111 acts as an enhancer of the transcriptional responses by mediating ubiquitination and degradation of SMAD3 inhibitors. Interacts with STUB1, HSPA1A, HSPA1B, HSP90AA1 and HSP90AB1.
功能:
Receptor-regulated SMAD (R-SMAD) that is an intracellular signal transducer and transcriptional modulator activated by TGF-beta (transforming growth factor) and activin type 1 receptor kinases. Binds the TRE element in the promoter region of many genes that are regulated by TGF-beta and, on formation of the SMAD3/SMAD4 complex, activates transcription. Also can form a SMAD3/SMAD4/JUN/FOS complex at the AP-1/SMAD site to regulate TGF-beta-mediated transcription. Has an inhibitory effect on wound healing probably by modulating both growth and migration of primary keratinocytes and by altering the TGF-mediated chemotaxis of monocytes. This effect on wound healing appears to be hormone-sensitive. Regulator of chondrogenesis and osteogenesis and inhibits early healing of bone fractures. Positively regulates PDPK1 kinase activity by stimulating its dissociation from the 14-3-3 protein YWHAQ which acts as a negative regulator.
亚细胞位置:
Cytoplasm
Nucleus
Cytoplasmic and nuclear in the absence of TGF-beta. On TGF-beta stimulation, migrates to the nucleus when complexed with SMAD4. Through the action of the phosphatase PPM1A, released from the SMAD2/SMAD4 complex, and exported out of the nucleus by interaction with RANBP1. Co-localizes with LEMD3 at the nucleus inner membrane. MAPK-mediated phosphorylation appears to have no effect on nuclear import. PDPK1 prevents its nuclear translocation in response to TGF-beta.

猪hMAD-3(SMAD3)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hMAD-3(SMAD3)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hMAD-3(SMAD3)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hMAD-3(SMAD3)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hMAD-3(SMAD3)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hMAD-3(SMAD3)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hMAD-3(SMAD3)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hMAD-3(SMAD3)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。
