Abstract

How are proteins recognized as substrates for ubiquitination? Here we summarize insights from recent experiments that address this issue. These highlight the diversity and complexity of determinants for substrate recognition, and raise many questions for further investigation. Copyright © 2002 John Wiley & Sons, Ltd.
