The amino acid sequence of the dual specificity mitogen-activated protein kinase kinase (MAPKK) has been determined by cDNA cloning and amino acid sequencing. MAPKK (393 residues, Mr 43,330) is a new member of the protein kinase subclass that comprises byr1 and STE7 that are involved in pheromone dependent signal transduction in yeast, wis1 a mitotic regulator in S. pombe and PBS2, which confers antibiotic resistance in S. cerevisiae.
通过cDNA克隆和氨基酸测序确定了双特异性丝裂原活化蛋白激酶激酶(MAPKK)的氨基酸序列。MAPKK(393个残基,分子量43,330)是蛋白激酶亚类的一个新成员,该亚类包括参与酵母中信息素依赖性信号转导的byr1和STE7、粟酒裂殖酵母中的有丝分裂调节因子wis1以及酿酒酵母中赋予抗生素抗性的PBS2。
