摘要：

Cancer cells depend on multiple. locally produced growth factors. Signaling by growth factors entails phosphorylation events. and its termination is determined primarily by endocytosis of growth factor receptor complexes, One group of growth factor receptors frequently implicated in human cancer is the ErbB family of receptor tyrosine kinases. By using ErbB as a prototype, here we review the role of protein ubiquitylation in the process that terminates signaling. Specifically, we concentrate on several adaptor proteins, including c-Cbl and Hgs, to elucidate the complexity of receptor sorting for degradation. Detailed understanding of ubiquitylation control on receptor desensitization may lead to better ways to diagnose and eradicate cancer. (C) 2002 Elsevier Science Ltd. All rights reserved.
