中文摘要

人类蛋白编码基因通过来自祖先基因的结构域重排而进化。我们开发了一种可扩展的、进化引导的方法,从同一蛋白家族内的组成结构域组装新基因,称为 DESynR(通过合成和重组进行结构域工程化)基因。在原代人 T 细胞中,DESynR 激活蛋白-1(AP-1)转录因子(TFs)在体外和体内抗肿瘤试验中显著优于天然 AP-1 TFs。DESynR AP-1 TFs 诱导广泛的转录和表观遗传重编程,并建立非天然 T 细胞状态,这些状态优化耗竭、效应和细胞毒功能以及持续性等特征——有时会征用来自不同细胞类型的基因模块。重编程主要由对已建立的 AP-1 结合调控元件的差异性调控驱动,而非独特结合。

最后,我们筛选 DESynR 红细胞转化特异性(ETS)和叉头框(FOX)TFs,以支持跨蛋白家族的普适性。总体而言,我们证明,重新配置现有的蛋白结构域可能发现非进化产生的基因,这些基因可编程具有治疗相关性的细胞状态。

Human protein-coding genes evolved via rearrangement of domains from ancestral genes.

We develop a scalable, evolutionarily guided method to assemble novel genes from constituent domains within a protein family, termed DESynR (domain engineered via synthesis and recombination) genes. In primary human T cells, DESynR activator protein-1 (AP-1) transcription factors (TFs) significantly outperform natural AP-1 TFs across in vitro and in vivo antitumor assays.

DESynR AP-1 TFs induce broad transcriptional and epigenetic reprogramming and establish non-natural T cell states that optimize features of exhaustion, effector and cytotoxic function, and persistence-sometimes co-opting gene modules from disparate cell types. Reprogramming is primarily driven by differential regulation of established AP-1-bound regulatory elements rather than unique binding.

Finally, we screen DESynR erythroblast transformation-specific (ETS) and forkhead box (FOX) TFs to support generalizability across protein families.

Overall, we demonstrate that reconfiguring existing protein domains may uncover non-evolved genes that program therapeutically relevant cell states.
