诱变提供了对蛋白质的深入了解,但直到最近才有将基因型与表型相结合的分析被用于在单个实验中评估多达一百万个蛋白质突变版本的活性。这种方法——“深度突变扫描”——产生了大规模的数据集,可以揭示内在的蛋白质特性、细胞内的蛋白质行为以及人类遗传变异的后果。深度突变扫描正在改变蛋白质的研究,但要实现其前景,必须解决许多挑战。
Mutagenesis provides insight into proteins, but only recently have assays that couple genotype to phenotype been used to assess the activities of as many as a million mutant versions of a protein in a single experiment. This approach – “deep mutational scanning” – yields large-scale datasets that can reveal intrinsic protein properties, protein behavior within cells and the consequences of human genetic variation. Deep mutational scanning is transforming the study of proteins, but many challenges must be tackled to fulfill its promise.
