The directed movement of substances from endosomes to lysosomes.

The directed movement of substances from endosomes to lysosomes.

Any process that affects the structure and integrity of a protein, altering the likelihood of its degradation or aggregation.

The homotypic fusion of endocytic vesicles to form or add to an early endosome.

The homotypic fusion of endocytic vesicles to form or add to an early endosome.

The directed movement of a toxin into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.

Any process that modulates the frequency, rate or extent of organelle assembly.

Any process that modulates the frequency, rate or extent of organelle assembly.

Any process that activates or increases the frequency, rate or extent of cellular protein catabolic process.

Any process that activates or increases the frequency, rate or extent of cellular protein catabolic process.

Any process that activates or increases the frequency, rate or extent of protein targeting to mitochondrion.

Any process that activates or increases the frequency, rate or extent of early endosome to late endosome transport.

Any process that activates or increases the frequency, rate or extent of early endosome to late endosome transport.

The lipid bilayer surrounding the lysosome and separating its contents from the cell cytoplasm.

A small lytic vacuole that has cell cycle-independent morphology and is found in most animal cells and that contains a variety of hydrolases, most of which have their maximal activities in the pH range 5-6. The contained enzymes display latency if properly isolated. About 40 different lysosomal hydrolases are known and lysosomes have a great variety of morphologies and functions.

A vacuole to which materials ingested by endocytosis are delivered.

A vacuole to which materials ingested by endocytosis are delivered.

A membrane-bounded organelle that receives incoming material from primary endocytic vesicles that have been generated by clathrin-dependent and clathrin-independent endocytosis; vesicles fuse with the early endosome to deliver cargo for sorting into recycling or degradation pathways.

A prelysosomal endocytic organelle differentiated from early endosomes by lower lumenal pH and different protein composition. Late endosomes are more spherical than early endosomes and are mostly juxtanuclear, being concentrated near the microtubule organizing center.

A filamentous structure formed of a two-stranded helical polymer of the protein actin and associated proteins. Actin filaments are a major component of the contractile apparatus of skeletal muscle and the microfilaments of the cytoskeleton of eukaryotic cells. The filaments, comprising polymerized globular actin molecules, appear as flexible structures with a diameter of 5-9 nm. They are organized into a variety of linear bundles, two-dimensional networks, and three dimensional gels. In the cytoskeleton they are most highly concentrated in the cortex of the cell just beneath the plasma membrane.

A membrane-bounded intracellular vesicle formed by invagination of the plasma membrane around an extracellular substance. Endocytic vesicles fuse with early endosomes to deliver the cargo for further sorting.

A multimeric protein complex that associates with the vacuolar membrane, late endosomal (multivesicular body) and lysosomal membranes. HOPS is a tethering complex involved in vesicle fusion.

A multimeric protein complex that acts as an endosomal tethering complex (CORVET = class C core vacuole/endosome tethering) by cooperating with Rab GTPases to capture endosomal vesicles and trap them prior to the action of SNAREs; the complex is involved in endo-lysosomal biogenesis and required for transport between endosome and vacuole. The Saccharomyces cerevisiae complex contains Vps8p, Vps3p, Pep5p, Vps16p, Pep3p, and Vps33p.

A specialized region of the plasma membrane and cell cortex of a presynaptic neuron; encompasses a region of the plasma membrane where synaptic vesicles dock and fuse, and a specialized cortical cytoskeletal matrix.
