Phosphorylation of the medium chain subunit of the AP-2 adaptor complex does not influence its interaction with the tyrosine based internalisation motif of TGN38. (1/337)

Tyrosine based motifs conforming to the consensus YXXphi (where phi represents a bulky hydrophobic residue) have been shown to interact with the medium chain subunit of clathrin adaptor complexes. These medium chains are targets for phosphorylation by a kinase activity associated with clathrin coated vesicles. We have used the clathrin coated vesicle associated kinase activity to specifically phosphorylate a soluble recombinant fusion protein of mu2, the medium chain subunit of the plasma membrane associated adaptor protein complex AP-2. We have tested whether this phosphorylation has any effect on the interaction of mu2 with the tyrosine based motif containing protein, TGN38, that has previously been shown to interact with mu2. Phosphorylation of mu2 was shown to have no significant effect on the in vitro interaction of mu2 with the cytosolic domain of TGN38, indicating that reversible phosphorylation of mu2 does not play a role in regulating its direct interaction with tyrosine based internalisation motifs. In addition, although a casein kinase II-like activity has been shown to be associated with clathrin coated vesicles, we show that mu2 is not phosphorylated by casein kinase II implying that another kinase activity is present in clathrin coated vesicles. Furthermore the kinase activity associated with clathrin coated vesicles was shown to be capable of phosphorylating dynamin 1. Phosphorylation of dynamin 1 has previously been shown to regulate its interaction with other proteins involved in clathrin mediated endocytosis.  (+info)

Inhibition of the receptor-binding function of clathrin adaptor protein AP-2 by dominant-negative mutant mu2 subunit and its effects on endocytosis. (2/337)

Although interactions between the mu2 subunit of the clathrin adaptor protein complex AP-2 and tyrosine-based internalization motifs have been implicated in the selective recruitment of cargo molecules into coated pits, the functional significance of this interaction for endocytosis of many types of membrane proteins remains unclear. To analyze the function of mu2-receptor interactions, we constructed an epitope-tagged mu2 that incorporates into AP-2 and is targeted to coated pits. Mutational analysis revealed that Asp176 and Trp421 of mu2 are involved in the interaction with internalization motifs of TGN38 and epidermal growth factor (EGF) receptor. Inducible overexpression of mutant mu2, in which these two residues were changed to alanines, resulted in metabolic replacement of endogenous mu2 in AP-2 complexes and complete abrogation of AP-2 interaction with the tyrosine-based internalization motifs. As a consequence, endocytosis of the transferrin receptor was severely impaired. In contrast, internalization of the EGF receptor was not affected. These results demonstrate the potential usefulness of the dominant-interfering approach for functional analysis of the adaptor protein family, and indicate that clathrin-mediated endocytosis may proceed in both a mu2-dependent and -independent manner.  (+info)

Splice variants of intersectin are components of the endocytic machinery in neurons and nonneuronal cells. (3/337)

We recently identified and cloned intersectin, a protein containing two Eps15 homology (EH) domains and five Src homology 3 (SH3) domains. Using a newly developed intersectin antibody, we demonstrate that endogenous COS-7 cell intersectin localizes to clathrin-coated pits, and transfection studies suggest that the EH domains may direct this localization. Through alternative splicing in a stop codon, a long form of intersectin is generated with a C-terminal extension containing Dbl homology (DH), pleckstrin homology (PH), and C2 domains. Western blots reveal that the long form of intersectin is expressed specifically in neurons, whereas the short isoform is expressed at lower levels in glia and other nonneuronal cells. Immunofluorescence analysis of cultured hippocampal neurons reveals that intersectin is found at the plasma membrane where it is co-localized with clathrin. Ibp2, a protein identified based on its interactions with the EH domains of intersectin, binds to clathrin through the N terminus of the heavy chain, suggesting a mechanism for the localization of intersectin at clathrin-coated pits. Ibp2 also binds to the clathrin adaptor AP2, and antibodies against intersectin co-immunoprecipitate clathrin, AP2, and dynamin from brain extracts. These data suggest that the long and short forms of intersectin are components of the endocytic machinery in neurons and nonneuronal cells.  (+info)

A structural explanation for the binding of multiple ligands by the alpha-adaptin appendage domain. (4/337)

The alpha subunit of the endocytotic AP2 adaptor complex contains a 30 kDa "appendage" domain, which is joined to the rest of the protein via a flexible linker. The 1.9 A resolution crystal structure of this domain reveals a single binding site for its ligands, which include amphiphysin, Eps15, and epsin. This domain when overexpressed in COS7 fibroblasts is shown to inhibit transferrin uptake, whereas mutants in which interactions with its binding partners are abolished do not. DPF/W motifs present in appendage domain-binding partners are shown to play a crucial role in their interactions with the domain. A single site for binding multiple ligands would allow for temporal and spatial regulation in the recruitment of components of the endocytic machinery.  (+info)

Dynamin-dependent endocytosis of ionotropic glutamate receptors. (5/337)

Little is known about the mechanisms that regulate the number of ionotropic glutamate receptors present at excitatory synapses. Herein, we show that GluR1-containing alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors (AMPARs) are removed from the postsynaptic plasma membrane of cultured hippocampal neurons by rapid, ligand-induced endocytosis. Although endocytosis of AMPARs can be induced by high concentrations of AMPA without concomitant activation of N-methyl-D-aspartate (NMDA) receptors (NMDARs), NMDAR activation is required for detectable endocytosis induced by synaptically released glutamate. Activated AMPARs colocalize with AP2, a marker of endocytic coated pits, and endocytosis of AMPARs is blocked by biochemical inhibition of clathrin-coated pit function or overexpression of a dominant-negative mutant form of dynamin. These results establish that ionotropic receptors are regulated by dynamin-dependent endocytosis and suggest an important role of endocytic membrane trafficking in the postsynaptic modulation of neurotransmission.  (+info)

Association of AP1 adaptor complexes with GLUT4 vesicles. (6/337)

Nycodenz gradients have been used to examine the in vitro effects of GTP-(gamma)-S on adaptor complex association with GLUT4 vesicles. On addition of GTP-(gamma)-S, GLUT4 fractionates as a heavier population of vesicles, which we suggest is due to a budding or coating reaction. Under these conditions there is an increase in co-sedimentation of GLUT4 with AP1, but not with AP3. Western blotting of proteins associated with isolated GLUT4 vesicles shows the presence of high levels of AP1 and some AP3 but very little AP2 adaptor complexes. Cell free, in vitro association of the AP1 complex with GLUT4 vesicles is increased approximately 4-fold by the addition of GTP-(gamma)-S and an ATP regenerating system. Following GTP-(gamma)-S treatment in vitro, ARF is also recruited to GLUT4 vesicles, and the temperature dependence of ARF recruitment closely parallels that of AP1. The recruitment of both AP1 and ARF are partially blocked by brefeldin A. These data demonstrate that the coating of GLUT4 vesicles can be studied in isolated cell-free fractions. Furthermore, at least two distinct adaptor complexes can associate with the GLUT4 vesicles and it is likely that these adaptors are involved in mediating distinct intracellular sorting events at the level of TGN and endosomes.  (+info)

The leucine-based sorting motifs in the cytoplasmic domain of the invariant chain are recognized by the clathrin adaptors AP1 and AP2 and their medium chains. (7/337)

Recognition of sorting signals within the cytoplasmic tail of membrane proteins by adaptor protein complexes is a crucial step in membrane protein sorting. The three known adaptor complexes, AP1, AP2, and AP3, have all been shown to recognize tyrosine- and leucine-based sorting signals, which are the most common sorting signals within membrane protein cytoplasmic tails. Although tyrosine-based signals are recognized by the micro-chains of adaptor complexes, the subunit recognizing leucine-based sorting signals is less clear. In this report we show by surface plasmon resonance that the two leucine-based sorting signals within the cytoplasmic tail of the invariant chain bind independently from each other to AP1 and AP2 but not to AP3. We also show that both motifs can be recognized by the micro-chains of AP1 and AP2. Moreover, by using monomeric as well as trimeric invariant chain constructs, we show that adaptor binding does not require trimerization of the invariant chain.  (+info)

Internalization of proximal tubular type II Na-P(i) cotransporter by PTH: immunogold electron microscopy. (8/337)

Physiological/pathophysiological alterations in proximal tubular P(i) reabsorption are associated with an altered brush-border membrane (BBM) expression of type II Na-P(i) cotransporter molecules. Reduction is achieved by an internalization and lysosomal degradation and an increase in P(i) reabsorption by new synthesis and BBM insertion of type II Na-P(i) cotransporters. In the present study, we investigated by immunohistochemistry and immunogold electron microscopy the routing of internalized rat type II Na-P(i) cotransporters (NaPi-2). In kidney of rats on a chronic low-P(i) diet, NaPi-2 is mainly localized in the BBM, in cisterns of the Golgi apparatus and sparsely also in large endocytotic vacuoles and lysosomes. Fifteen minutes after the injection of the 1-34 analog of parathyroid hormone (PTH), the amount of NaPi-2 was decreased in the BBM and increased in endocytotic vesicles. NaPi-2 molecules colocalized with horseradish peroxidase injected prior to the injection of PTH. Vesicles labeled for NaPi-2 were occasionally also labeled for clathrin or the adaptor protein AP2. We conclude that NaPi-2 molecules enter the subapical compartment from where NaPi-2-containing vesicles are segregated off and directed to the lysosomes. A clathrin-mediated pathway may contribute to the PTH-induced internalization of NaPi-2.  (+info)

The AP-complex family (Boehm and Bonifacino, 2001; Nakatsu and Ohno, 2003; Owen et al., 2004; Robinson, 2004) has six members in mammals. AP-1A, AP-2, AP-3A and AP-4 are ubiquitously expressed. The other two members, AP-5 and AP-6, are cell-type-specific isoforms of AP-1A and AP-3A: the epithelium-specific AP-1B and the neuron-restricted AP-3B.. The AP complexes consist of four subunits: one small (σ1-σ4), one medium (μ1-μ4) and two large (α, γ, δ or ϵ; and β1-β4) subunits. These assemble to form a structure in which two appendage domains are connected by flexible hinge regions to the core (Owen et al., 2004; Owen and Luzio, 2000; Robinson, 2004). The large subunits are divided into three domains: the N-terminal domain, which makes up the core with the μ and σ subunits; the hinge domain, and the C-terminal appendage. One of the large subunits (α, γ, δ or ϵ) is implicated in binding to the target membrane (Collins et al., 2002; Nakatsu and Ohno, 2003; Owen et al., 2004; Traub, ...

Current scientific tests which include ours, discovered a novel role of Rho3 in the Golgi/ endosomal trafficking, partly through bodily and/or purposeful conversation with the clathrin-associated adaptor protein-1 (AP-1) intricate and Cdc42 in fission yeast [9,10]. We also confirmed that the AP-1 complex mutant strains confirmed flaws in Golgi/ endosomal trafficking, secretion and vacuole fusion [eleven,twelve] and that Sip1, the AP-one accent recruits the AP-1 complicated to the Golgi/endosomes by figuring out the sip1-i4 mutant allele, which abolished the endosomal localization of the AP-1 complicated [13]. Sip1 is a homolog of Laa1 in the budding yeast [fourteen] and p200 in increased eukaryotes [fifteen], the two of which belong to the rising family members of AP-1 interacting associates. To realize the molecular operate of the AP-one accessory protein and elucidate the pathways interacting with Sip1/AP-one-mediated trafficking, we screened for the multi-duplicate suppressor of the ...

Toxoplasma gondii possesses a highly polarized secretory system, which efficiently assembles de novo micronemes and rhoptries during parasite replication. These apical secretory organelles release their contents into host cells promoting parasite invasion and survival. Using a CreLox-based inducible knock-out strategy and the ddFKBP over-expression system, we unraveled novel functions of the clathrin adaptor complex TgAP1. First, our data indicate that AP1 in T. gondii likely functions as a conserved heterotetrameric complex composed of the four subunits γ, β, μ1, σ1 and interacts with known regulators of clathrin-mediated vesicular budding such as the unique ENTH-domain containing protein, which we named Epsin-like protein (TgEpsL). Disruption of the μ1 subunit resulted in the mis-sorting of microneme proteins at the level of the Trans-Golgi-Network (TGN). Furthermore, we demonstrated that TgAP1 regulates rhoptry biogenesis by activating rhoptry protein exit from the TGN, but also ...
In the present work, we have investigated mechanisms involved in the nucleotide-dependent regulation of clathrin-coated pit nucleation at the synapse. Our results implicate ARF6 in this process and demonstrate two effects of the GTP-bound form of this small GTPase; stimulation of the recruitment of clathrin/AP-2 to presynaptic membranes and binding plus activation of PIPKIγ. They also suggest that the two effects are related and that PI(4,5)P2 production by PIPKIγ stimulation represents the major mechanism through which ARF6 enhances clathrin/AP-2 recruitment. The action of GTP-ARF6 on clathrin/AP-2 recruitment mimics the effect of GTPγs, and its effects are antagonized by experimental manipulations that prevent either ARF activation (i.e., dominant-negative ARF6) or PI(4,5)P2 production and availability (i.e., kinase inhibition, PIPKIγ depletion, and PI(4,5)P2 hydrolysis by synaptojanins inositol 5′-phosphatase domain). These results strongly indicate that enhanced clathrin coat ...
The heterotetrameric adaptor protein complex AP2 is one of the best-studied components of the endocytic machinery. The AP2 complex consists of four different subunits, α, β2, σ2, and μ2, which assemble into a core domain with two appendages (Fig. 2; Collins et al., 2002; Jackson et al., 2010). AP2 has multiple binding partners, including phosphatidylinositol 4,5-bisphosphate (PIP2), clathrin, several endocytic accessory proteins, and two signaling motifs present on some cargo receptors (see Traub, 2009 for a detailed review). The AP2 complex has classically been considered to be the master initiator of clathrin-mediated endocytosis through its role in recruiting clathrin molecules to the membrane. However, several lines of evidence question this idea.. If the AP2 complex has an essential role in initiation then its presence would be required for the formation of endocytic sites. However, in yeast the endocytosis of mating pheromone α-factor is unaffected in strains lacking functional AP2 ...
Proteins internalized at the cell surface by clathrin-mediated endocytosis contain specific sorting sequences that bind to the internalization machinery. The best characterized of these is the tyrosine-based YXXΦ motif (in which X is any residue and Φ is a bulky, hydrophobic residue). This binds to a specific region in the μ2 subunit of the AP2 clathrin adaptor protein, and structural studies have shown that the spacing between the Y and Φ residues is crucial. Ruth Murrell and co-workers now unveil a novel type of tyrosine-based endocytic motif (p. 3073). They have used site-directed mutagenesis and CD8-based chimeras to analyse endocytosis of P2X4 receptors, ATP-gated cation channels that rapidly cycle off the plasma membrane. These receptors possess consensus YXXΦ motifs, but surprisingly these are inaccessible to AP2 and not needed for endocytosis. Instead, the authors show, a downstream YXXGΦ motif is required. Determining the structure of a YXXGΦ-μ2 complex, they demonstrate that ...

To obtain insights into the mechanism by which FCHo2 couples CCP growth and lifetime in CME, we analyzed the nanoscale localization of FCHo2 at CCPs. Dual-color SD-dSTORM (spectral demixing direct stochastic optical reconstruction microscopy) analysis of the distribution of endogenous FCHo2 within CCPs followed by quantitative averaging of ,250 images revealed a marked concentration of FCHo2 in ring-like structures (about 225 nm in diameter) at the outer rim of CCPs [consistent with (27)] while being largely absent from the CCP center (Fig. 3, D and E) that eventually gives rise to the dome as CCPs invaginate. Hence, FCHo2 selectively accumulates at the rim of CCPs, consistent with its early role in coupling CCP growth and dynamics.. Different models have been proposed regarding the early endocytic function of FCHo2. According to one model, FCHo2 nucleates CCPs by acting as a plasma membrane-associated recruitment hub for early-acting endocytic proteins bound to its μ-homology domain (20). This ...
