Transcription factors are often targeted for rapid degradation by the ubiquitin-proteasome system. Recent evidence points to a correlation between the potency and instability of transcriptional activators, suggesting a possible direct role for ubiquitin-dependent proteolysis in transcriptional activation.
转录因子常常是泛素-蛋白酶体系统快速降解的作用靶点。最近的证据表明转录激活因子的活性与其不稳定性之间存在关联,这表明泛素依赖性蛋白水解在转录激活过程中可能具有直接作用。
