Description:
Epidermal growth factor receptor (EGFR) signaling was analyzed in mammalian cells conditionally defective for receptor-mediated endocytosis. EGF-dependent cell proliferation was enhanced in endocytosis-defective cells. However, early EGF-dependent signaling events were not uniformly up-regulated. A subset of signal transducers required the normal endocytic trafficking of EGFR for full activation. Thus, endocytic trafficking of activated EGFR plays a critical role not only in attenuating EGFR signaling but also in establishing and controlling specific signaling pathways.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vieira, A V -- Lamaze, C -- Schmid, S L -- CA58689/CA/NCI NIH HHS/ -- CA69099/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1996 Dec 20;274(5295):2086-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, The Scripps Research Institute, La Jolla, CA 92037, USA. slschmid@scripps.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8953040" target="_blank"〉PubMed〈/a〉
