| 產品介紹 |
background: 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蛋白又稱：鳥苷酸結合蛋白，存在于全身各個組織和細胞中，G蛋白在信息傳遞中起到很重要的作用,參與細胞內外信息的相互傳導。 激素受體與腺苷酸環化酶是細胞膜上兩類分開的蛋白質。激素受體結合的部分在細胞膜的外表面，而腺苷環化酶在膜的胞漿面，在兩者之間存在一種起耦聯作用的調節蛋白——鳥苷酸結合蛋白（guanine nucleotide-binding regulatory protein）細胞受到各種刺激信息，包括化學性的激素和神經遞質及非化學性的聲音、圖像等。刺激信息通過G蛋白的激活作用，在胞漿中生成數目眾多的第二信使分子，產生十萬級放大效應，引起細胞興奮，讓后促動器官完成各自功能。 1977年，美國科學家阿爾弗雷德-戈德曼-吉爾曼(Alfred Goodman Gilman)發現了G蛋白及其在細胞興奮傳導方面的重要作用。1994年，吉爾曼因“G蛋白”方面的研究成果而榮獲諾貝爾生理及醫學獎。 |
