Here we describe, for the first time, that budding yeast mitogen-activated protein kinase Hog1 and its upstream activators Pbs2 and Ssk1 are essential for the response to arsenite. Hog1 is rapidly phosphorylated in response to arsenite and triggers a transcriptional response that involves the upregulation of genes essential for arsenite detoxification.
在此,我们首次描述了出芽酵母丝裂原活化蛋白激酶Hog1及其上游激活因子Pbs2和Ssk1对于亚砷酸盐应答至关重要。Hog1在亚砷酸盐刺激下迅速磷酸化,并引发转录应答,其中涉及对亚砷酸盐解毒至关重要的基因上调。
