The single peptide of bt - r3 protein is a a helix which orients from inside to outside , and the transmembrane domain is also a helix which orients from outside to inside Bt - r3受体蛋白最前端的信号肽是一个由内向外a螺旋，跨膜区域( tmd )是一个由外向内的a螺旋。
But the effects are inhibited partially by heparin . it showed that the ip3r - like protein in plant may mediate ip3 signal to regulate the stomatal guard cell movement 表明了植物中存在的类三磷酸肌醇受体蛋白可能介导了三磷酸肌醇信号对气孔保卫细胞运动的调节作用。
To activate t cells , one receptor responds to a specific foreign invader , or antigen , and another , cd28 , signals a green light for an immune response 一般t细胞的活化，除了要有一个特定外来物（抗原）与细胞表面受体结合，还需要另一个受体蛋白cd28发出免疫反应的绿灯信号。
It is possible that only the cadherin repeated domain 4 , 5 , 6 of bt - r3 protein is not enough for bt - r3 protein to bind bt toxic protein , or there is another bind site outside these domains 这可能是因为光有这些结构域对结合活性来说是不够的，还需要其它结构域协同。也有可能bt - r3受体蛋白和bt毒蛋白另有其结合位点。
The key mechanisms involved are inhibition of protein - phosphotyrosine phosphatases and activation of nonreceptor protein - tyrosine kinases , in an insulin - receptor tyrosine kinase independent fashion 钒在生物体内发挥作用的主要机制是通过蛋白磷酸酪氨酸磷酸酯酶的抑制和非受体蛋白酪氨酸的激活一种与胰岛素受体完全不同的途径发挥作用的。
Expression system renders products that are free of post - translational modifications , it is likely that the binding of crylab toxin to bt - r3 protein via protein - protein interaction and does not require glycosylation 且该受体蛋白与cry1ab的结合部位位于bt - r3受体蛋白的胞外结构域。 bt毒蛋白与钙粘蛋白受体的结合与受体是否糖基化无关。
Precursor cells from different lineages express different subsets of surface molecules , many of which are now difined by cluster of differentiation ( cd ) antigens . cd antigens associated with the plasma membranes of leukocytes may be molecules involved in a variety of functions 蛋白芯片可以将蛋白质以阵列的方式固定在经化学或生物酶处理的表面上，也可将受体蛋白、抗体等固定在表面上，未知分子可以利用与芯片不同位点亲和力来分析。
The cadherin repeated domains of bt - r3 protein share high homology with the cadherin domains from african clawed frog ( xenopus laevis ) and e - cadherin ( epithelial ) from mouse ( mus musculus ) . so , the 3rd structure of the cadherin repeated domains of bt - r3 protein should be similar to these domains Bt - r3受体蛋白的钙粘蛋白结构域分别与非洲爪蟾( xenopuslaevis )的钙粘蛋白胞外结构域和小鼠( musmusculus )的上皮钙粘蛋白胞外结构域有很高的同源性。
Some trends in the studies of cellular inorganic chemistry have been described in this review , which mainly contains the aspects of effects of metal ions including calcium ions and lanthanide ions and activated small molecule on ion channels , receptor proteins in the membrane , intracellular receptor proteins and cellular function 摘要本文评述了当前细胞无机化学研究中的几个方面，主要是包括钙离子和稀土离子在内的金属离子和活性小分子对细胞膜离子通道、膜受体蛋白、胞内受体蛋白以及对细胞功能的影响。
Ip3 - ip3 receptor ( ip3r ) interaction mediates the release of ca2 + from the endoplasmic reticulum in response to many different extracellular stimulus . for higher plants , however , though it is now generally accepted that ip3 participates in signal transduction in many important cellular processes , only limited evidence is available for the presence and properties of the ip3r - like protein so far . here , using the immunological methods with an antibody raised against a mammalian inositol 1 , 4 , 5 - triphophate receptor ( type 1 ) , we found that , 1 ) the antibody across - reacted the proteins with about 200kd in microsomes from oryza sativa and about 200kd from arabidopsis thaliana respectively 本实验用sds - page电泳和免疫印迹的方法，用哺乳动物大鼠三磷酸肌醇受体的多肽做抗体对类三磷酸肌醇受体蛋白鉴定，结果表明：抗体与水稻和拟南芥微粒体蛋白分子量大约为200kd的蛋白交叉反应，同时还发现在水稻微粒体蛋白62kd和拟南芥微粒体蛋白45kd处有交叉反应的蛋白条带存在，表明在植物中有类三磷酸肌醇受体蛋白的存在；用免疫胶体金方法，发现类三磷酸肌醇受体蛋白主要分布于液泡膜和细胞质膜上。
