Several other components of the basolateral machinery also await further analysis.

Military Training Routes (AP/1B)

AP1B is not a general basolateral sorting adaptor in all epithelia [ 85 ]. It is absent in hepatocytes [ 90 ] and retinal pigment epithelium RPE [ 91 ]. Ap1 head of title DOD.

C The new paradigm. Finding libraries that hold this item Please enter your name. A function-blocking antibody demonstrates that AP1B sorts basolateral proteins at Recycling Endosomes. Please re-enter recipient e-mail address es. One possibility might be ankyrin G, recently reported to participate in post-Golgi transport to the basolateral membrane [ ]. Only recently dedicated functional experiments provided the first direct evidence that clathrin is required for basolateral PM protein sorting [ 80 ] Fig.

Direct continuities between cisternae at different levels of the Golgi complex in glucose-stimulated mouse islet beta cells. Protein Motifs Comments References. Cloning and expression of gamma-adaptin, a component of clathrin-coated vesicles associated with the Golgi apparatus.

Subsequent experiments confirmed this notion and provided evidence that AP1B recruits to RE two subunits of the exocyst complex Sec8 and Exo70 [ 92 ], previously shown to participate in basolateral delivery [ 93 ].

Basolateral sorting of transforming growth factor-alpha precursor in polarized epithelial cells: Naked2 acts as a cargo recognition and targeting protein to ensure proper delivery and fusion of TGF-alpha containing exocytic vesicles at the lower lateral membrane of polarized MDCK cells. The EPP coordinates the activity of polarity proteins Crumbs, A;1b and Scribble Complexespolarity lipids PIP2, PIP3 and positional xp1b provided by cell—cell and cell—adhesion molecules to assemble epithelial-specific tight junctions, cytoskeletal re-arrangements and a Polarized Trafficking Machinery [ 1 ].

Myristoylated Naked2 escorts transforming growth factor alpha to the basolateral plasma membrane of polarized epithelial cells. Structural requirements for basolateral sorting of the human transferrin receptor in the biosynthetic and endocytic pathways of Madin-Darby canine kidney cells.

The experiments also suggest hypotheses that need to be tested by further experimental work, e. Ultrastructural and live imaging analyzes are required to determine whether conventional coated vesicles or some other form of clathrin-mediated transport is used by basolateral proteins leaving the TGN and CRE.

Secretory traffic triggers the formation of tubular continuities across Golgi sub-compartments. Your list has reached the maximum number of items.

This model dominated the field for 20 years. Annu Rev Cell Biol. Studies with viral envelope glycoproteins as model PM proteins suggested the concept that the TGN was the major sorting station in the biosynthetic route.

Unlike other basolateral proteins, E-cadherin appears to utilize a non-conventional recycling route to the basolateral membrane that include passage through both Tf positive RE and Rab11 positive ARE [ 3032 ].
