For the first time, a target miRNA-degraded protein was found
Time of Update: 2021-02-25
In addition, functional loss studies have shown that ZSWIM8 Cullin-RING connective enzymes accelerate the degradation of multiple miRNAs in mammalian, fruit flies, and worm cells, thus determining the half-life of most short-lived miRNAs. These results shed light on the mechanisms of TDMD and extend its role in shaping miRNA levels in animals.
