Abstract

Two decades into the twenty-first century, a confluence of breakthrough technologies wielded at the molecular level is presenting biologists with unique opportunities to unravel the complexities of the cellular world. CRISPR/Cas9 allows gene knock-outs, knock-ins, and single-base editing at chromosomal loci. RNA-based tools such as siRNA, antisense oligos, and morpholinos can be used to silence expression of specific genes. Meanwhile, protein knockdown tools that draw inspiration from natural regulatory mechanisms and facilitate elimination of native or degron-tagged proteins from cells are rapidly emerging. The acute and reversible reduction in protein levels enabled by these methods allows for precise determination of loss-of-function phenotypes free from secondary effects or compensatory adaptation that can confound nucleic-acid-based methods that involve slow depletion or permanent loss of a protein. In this Review, we summarize the ingenious ways biologists have exploited natural mechanisms for protein degradation to direct the elimination of specific proteins at will. This has led to advancements not only in basic research but also in the therapeutic space with the introduction of PROTACs into clinical trials for cancer patients.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
