An fast allen wichtigen Prozessen in unserem Körper sind Proteine beteiligt, und Störungen ihrer Funktion verursachen Krankheiten. Um zu verstehen, wie einzelne Proteine arbeiten, entfernen Forscher sie aus einer Zelle und analysieren die Effekte. Bisher gab es dafür prinzipiell zwei Methoden: die Genschere CRISPR/Cas und die RNA-Interferenz. Sie wirken auf der Ebene von DNA beziehungsweise RNA. Ihr Einfluss auf Proteine ist allerdings indirekt und braucht Zeit. Wissenschaftler aus Deutschland und Großbritannien präsentieren jetzt eine neue Methode, genannt Trim-Away, mit der es möglich ist, Proteine direkt und schnell in jeder Art von Zelle abzubauen. Da Trim-Away zwischen verschiedenen Varianten eines Proteins uehtmdzwcfuzu yufq, oshlzguu ox bnbi Hjowlhu rul czb Bzehdgln dwz Pxhtwzlbaus. (Mlmi, 25. Yiyrelzn 1891)
