2020年12月10日 · Focusing on retron Ec48, we show evidence that it “guards” RecBCD, a complex with central anti-phage functions in bacteria. Inhibition of RecBCD by phage proteins activates the retron, leading to abortive infection and cell death. Thus, the Ec48 retron forms a second line of defense that is triggered if the first lines of defense have ...

研究人员进一步将之与大小最小的逆转录酶（Marathon penta五突变逆转录酶）进行比较。结果显示evo-Ec48的平均性能比Marathon五突变体提高了3.7倍，接近了PEmax编辑效率。在人T细胞中验证结果也表明 PE6a 和 PE6b 在编辑效率上均明显优于其野生型RT，且与PEmax相当。

2020年11月23日 · 当RecBCD被噬菌体针对性抑制，Ec48防御系统就会激活效应基因，快速干掉感染细胞，以防感染进一步扩散。 可见拥有Ec48会使得噬菌体（红）无法进一步扩散

首先，研究人员通过将四种已被报道具有功能的retron系统 (Ec48、Ec73、Ec86和Ec107) 在哺乳动物细胞内的表达，证明了细菌retron系统能在哺乳动物细胞中逆转录产生单链DNA。

2022年11月12日 · Ec48可用于检测RecBCD蛋白的完整性，当外源噬菌体感染大肠杆菌时，噬菌体蛋白会抑制RecBCD，进而诱导激活胞内Ec48的效应蛋白。 该效应蛋白为跨膜蛋白，被激活后可改变细胞膜的通透性，从而导致大肠杆菌顿挫感染和细胞死亡，避免噬菌体大量增殖( 图 4A )。
