Abstract

de Almeida et al. (2021) developed a temporally controlled CRISPR-Cas9 screen to identify mechanisms controlling MYC levels and discovered that intact proteasomes are imported into the nucleus by AKIRIN2 binding to proteasomes at one end and a nuclear import receptor at the other.

摘要

德阿尔梅达等人(2021 年)开发了一种时间控制的 CRISPR-Cas9 筛选技术,以鉴定控制 MYC 水平的机制,并发现完整的蛋白酶体通过 AKIRIN2 与蛋白酶体的一端结合,与另一端的核输入受体结合,被导入细胞核。
