... investigate the role of the sterol in endocytosis, we used a substitution strategy to replace cholesterol with sterols that show various raft-forming abilities and chemical structures. Both clathrin-mediated endocytosis of transferrin and clathrin-independent endocytosis of clustered placental alkaline...

... in transferrin-receptor-positive early endosomes, suggesting that AGAP2 functions in the very early steps of retrograde sorting. A number of other intracellular trafficking pathways are not affected under these conditions. These results establish that Arf1 and AGAP2 have key trafficking functions...

... of AP-3 endosomes. We found that AGAP2 directly interacted with AP-1. AGAP2 colocalized with AP-1, transferrin receptor and Rab4 on endosomes. Overexpression of AGAP2 changed the intracellular distribution of AP-1 and promoted Rab4-dependent fast recycling of transferrin. Based on these results, we...

... (MVB) ESCRT GFR transferrin Internalised transferrin receptors (TR) and epidermal growth factor receptors (EGFR) are delivered to the early endosome, a common compartment consisting of tubules and vacuoles ( Gruenberg and Maxfield, 1995 ; Mellman, 1996 ; Trowbridge et al., 1993 ). Within...

... intracellular routes upon endocytosis by their receptors. Whereas LDL is degraded in lysosomes, lipophorin is recycled in a transferrin-like manner. We constructed several hybrid receptors composed of Locusta migratoria LpR and human LDLR regions to identify the domains implicated in LpR-mediated ligand...

The recycling vesicles also trafficked through a syntaxin 6-positive compartment but not the TGN38-positive...

... sucrose gradients combined with confocal microscopy by indirect immunofluorescence or stable expression of a Syt IX-green fluorescent fusion protein demonstrate that Syt IX colocalizes with internalized transferrin (Tfn) and with Rab 11 at the perinuclear ERC. Syt IX also colocalizes with tubulin...

To study the functional role of Syt III, we stably transfected RBL cells with Syt III antisense cDNA and monitored the route of transferrin (Tfn) internalization in cells that displayed...

.... Overexpressed SARA has been found on EEA1-positive early endosomes. In this report, we show that endogenous SARA is present on early endosomes and overexpression of SARA causes endosomal enlargement. Functionally, SARA overexpression significantly delays the recycling of transferrin. The transferrin receptor...

Fluorescently labeled RAP is also transported to this recycling organelle upon receptor-mediated endocytosis by iLR. Internalized HDLp eventually exits the cell via...
