Control of EGF receptor signaling by clathrin-mediated endocytosis.

چکیده
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.

EGF Receptor Signaling Stimulates SRC Kinase Phosphorylation of Clathrin, Influencing Clathrin Redistribution and EGF Uptake
Epidermal growth factor (EGF) binding to its receptor causes rapid phosphorylation of the clathrin heavy chain at tyrosine 1477, which lies in a domain controlling clathrin assembly. EGF-mediated clathrin phosphorylation is followed by clathrin redistribution to the cell periphery and is the product of downstream activation of SRC kinase by EGF receptor (EGFR) signaling. In cells lacking SRC ki...
متن کاملSelective regulation of clathrin-mediated epidermal growth factor receptor signaling and endocytosis by phospholipase C and calcium
Clathrin-mediated endocytosis is a major regulator of cell-surface protein internalization. Clathrin and other proteins assemble into small invaginating structures at the plasma membrane termed clathrin-coated pits (CCPs) that mediate vesicle formation. In addition, epidermal growth factor receptor (EGFR) signaling is regulated by its accumulation within CCPs. Given the diversity of proteins re...
متن کاملEpidermal growth factor–stimulated Akt phosphorylation requires clathrin or ErbB2 but not receptor endocytosis
Epidermal growth factor (EGF) binding to its receptor (EGFR) activates several signaling intermediates, including Akt, leading to control of cell survival and metabolism. Concomitantly, ligand-bound EGFR is incorporated into clathrin-coated pits--membrane structures containing clathrin and other proteins--eventually leading to receptor internalization. Whether clathrin might regulate EGFR signa...
متن کاملClathrin-mediated endocytosis in AP-2–depleted cells
We have used RNA interference to knock down the AP-2 mu2 subunit and clathrin heavy chain to undetectable levels in HeLaM cells. Clathrin-coated pits associated with the plasma membrane were still present in the AP-2-depleted cells, but they were 12-fold less abundant than in control cells. No clathrin-coated pits or vesicles could be detected in the clathrin-depleted cells, and post-Golgi memb...
متن کاملSynaptojanin 2, a novel Rac1 effector that regulates clathrin-mediated endocytosis
The small GTPase Rac has been implicated in a wide range of cellular processes, including the organization of the actin cytoskeleton, transcriptional control and endocytic vesicle trafficking [1-3]. The signaling components that mediate these functions downstream of Rac largely remain to be identified. In this study, we have identified synaptojanin 2, a polyphosphoinositide phosphatase as a nov...
