| 产品介绍 | G protein beta subunit GI/GS/GT (guanine nucleotide-binding protein G). WD40 domain, found in a number of eukaryotic proteins that cover a wide variety of functions including adaptor/regulatory modules in signal transduction, pre-mRNA processing and cytoskeleton assembly; typically contains a GH dipeptide 11-24 residues from its N-terminus and the WD dipeptide at its C-terminus and is 40 residues long, hence the name WD40; between GH and WD lies a conserved core; serves as a stable propeller-like platform to which proteins can bind either stably or reversibly; forms a propeller-like structure with several blades where each blade is composed of a four-stranded anti-parallel b-sheet; instances with few detectable copies are hypothesized to form larger structures by dimerization; each WD40 sequence repeat forms the first three strands of one blade and the last strand in the next blade; the last C-terminal WD40 repeat completes the blade structure of the first WD40 repeat to create the closed ring propeller-structure; residues on the top and bottom surface of the propeller are proposed to coordinate interactions with other proteins and/or small ligands; 7 copies of the repeat are present in this alignment. Function: Guanine nucleotide-binding proteins (G proteins) are involved as a modulator or transducer in various transmembrane signaling systems. The beta and gamma chains are required for the GTPase activity, for replacement of GDP by GTP, and for G protein-effector interaction. Subunit: G proteins are composed of 3 units, alpha, beta and gamma. Interacts with ARHGEF18 and RASD2. The heterodimer formed by GNB1 and GNG2 interacts with PTH1R (via C-terminus). Post-translational modifications: Phosphorylation at His-266 by NDKB contributes to G protein activation by increasing the high energetic phosphate transfer onto GDP. Similarity: Belongs to the WD repeat G protein beta family. Contains 7 WD repeats.

G蛋白又称：鸟苷酸结合蛋白，存在于全身各个组织和细胞中，G蛋白在信息传递中起到很重要的作用,参与细胞内外信息的相互传导。 激素受体与腺苷酸环化酶是细胞膜上两类分开的蛋白质。激素受体结合的部分在细胞膜的外表面，而腺苷环化酶在膜的胞浆面，在两者之间存在一种起耦联作用的调节蛋白——鸟苷酸结合蛋白（guanine nucleotide-binding regulatory protein）细胞受到各种刺激信息，包括化学性的激素和神经递质及非化学性的声音、图像等。刺激信息通过G蛋白的激活作用，在胞浆中生成数目众多的第二信使分子，产生十万级放大效应，引起细胞兴奋，让后促动器官完成各自功能。 1977年，美国科学家阿尔弗雷德-戈德曼-吉尔曼(Alfred Goodman Gilman)发现了G蛋白及其在细胞兴奋传导方面的重要作用。1994年，吉尔曼因“G蛋白”方面的研究成果而荣获诺贝尔生理及医学奖。 |
