...Qian Wang; Xinmei Chen; Zhixiang Wang ABSTRACT We have shown previously that epidermal growth factor (EGF) receptor (EGFR) endocytosis is controlled by EGFR dimerization. However, it is not clear how the dimerization drives receptor internalization. We propose that EGFR endocytosis is driven...

...Arola Fortian; Alexander Sorkin ABSTRACT Activation of epidermal growth factor (EGF) receptor (EGFR) leads to its interaction with Grb2, a dual-function adapter mediating both signaling through Ras and receptor endocytosis. We used time-lapse three-dimensional imaging by spinning disk confocal...

..., Tiam1 and Vav2 have been shown to transduce the growth signal from the EGF receptor to Rac1. To clarify the role of each GEF, we time-lapse imaged the EGF-induced activity change of Rac1 in A431 cells transfected with siRNA targeting each Rac1 GEF. Because knockdown of these GEFs suppressed EGF-induced...

...Amy Tsacoumango; Song Jae Kil; Liping Ma; Frank D. Sönnichsen; Cathleen Carlin One of the main goals of this study was to understand the relationship between an epidermal growth factor (EGF) receptor dileucine (LL)-motif (679-LL) required for lysosomal sorting and the protein ubiquitin ligase CBL...

... was not essential for Arp2/3-complex-mediated actin assembly at these sites or for EGF receptor-mediated endocytosis, N-WASP deficiency caused a marked reduction of EGF internalization. We conclude that the assembly of WASP subfamily proteins and associated factors at sites of clathrin-coated pit invagination...

...Annemieke A. de Melker; Gerda van der Horst; Jannie Borst c-Cbl associates with the activated EGF receptor before endocytosis. We here reveal that the capacity of c-Cbl to promote receptor internalization depends on its ubiquitin ligase activity, which functionally connects the EGF receptor...

We find that EGF treatment of NR6 fibroblasts presenting full-length WT EGF receptors (EGFR) reduces the fraction of cells presenting focal adhesions from ~60% to ~30% within 10 minutes. The dose dependency of focal adhesion disassembly mirrors that for EGF-enhanced cell...
