    • The present invention relates to a method for screening agoist or antagonist of human seven transmembrane protein 1 (hSTM1) which is a human orphan G-protein coupled receptor (GPCR) and more specifically, to a method for screening agonist or antagonist of hSTM1 using yeasts which express hSTM1 protein, to a method for identifying activities of hSTM1 regulator using the yeasts which express hSTM1 protein, to a method for screening agonist or antagonist of hSTM1 by treating yeasts which express guanidine nucleotide binding protein, alpha inhibiting activity polypeptide 3 (Gnai3) protein and hSTM1 protein with agonist or antagonist candidate substances or agonist or antagonist candidate substances and pertussis toxin (PTX) and identifying growth level of the yeasts treated with the candidate substances, to a screening kit of the agonist or the antagonist of the hSTM1, and to a yeast transformant to which an expression vector including polynucleotide which codes the hSTM1 protein, and activities of Ras1 protein is more reduced than wild type. [Reference numerals] (AA) Activator candidate drugs; (BB,CC) Vector; (DD) More increase apoptosis by drug activities; (EE) Inhibitor candidate drugs; (FF) Recover cell growth by drug activities; (GG) Cytotoxic materials; (HH) All strains are died by drugs
    • 本发明涉及用于筛选作为人类孤儿G蛋白偶联受体(GPCR)的人七跨膜蛋白1(hSTM1)的前者或拮抗剂的方法,更具体地涉及使用酵母筛选hSTM1的激动剂或拮抗剂的方法 表达hSTM1蛋白的方法,用于通过处理表达胍核苷酸结合蛋白的酵母,α抑制活性多肽3(Gnai3)来筛选hSTM1的激动剂或拮抗剂来筛选表达hSTM1蛋白的hSTM1调节剂的活性的方法, 蛋白质和hSTM1蛋白与激动剂或拮抗剂候选物质或激动剂或拮抗剂候选物质和百日咳毒素(PTX),并鉴定用候选物质处理的酵母的生长水平,到hSTM1的激动剂或拮抗剂的筛选试剂盒,以及 涉及包含编码hSTM1蛋白的多核苷酸的表达载体的酵母转化体, Ras1蛋白质的变异比野生型更为降低。 (参考号)(AA)活化剂候选药物; (BB,CC)矢量; (DD)药物活性增加细胞凋亡; (EE)抑制剂候选药物; (FF)通过药物活性恢复细胞生长; (GG)细胞毒性物质; (HH)所有菌株均被药物死亡
