There is widespread interest in developing fluorescent reporters of protein kinase activity, species that can furnish a visual readout of both when and where intracellular kinases are activated in response to a stimulus. We have constructed and identified, via a combination of rational design, library synthesis, and screening, a difluorofluorescein-appended peptide-based species that responds to protein
开发蛋白激酶活性的荧光报告基因引起了广泛的兴趣,这些物种可以提供细胞内激酶响应刺激的时间和地点的视觉读数。我们通过合理设计、文库合成和筛选相结合,构建并鉴定了一种以荧光敏感方式响应蛋白激酶 C 磷酸化的二氟荧光素附加肽基物种。磷酸化诱导的二价金属离子介导的 265%增强荧光继续与 8.5 micromol/min.mg 的 V(max) 和 20.5 microM 的 K(m)。
