  2. Vesicular transport adaptor protein - Wikipedia

    en.wikipedia.org/wiki/Vesicular_transport...

    Vesicular transport adaptor proteins are proteins involved in forming complexes that function in the trafficking of molecules from one subcellular location to another. [2] [3] [4] These complexes concentrate the correct cargo molecules in vesicles that bud or extrude off of one organelle and travel to another location, where the cargo is ...

  3. Intracellular transport - Wikipedia

    en.wikipedia.org/wiki/Intracellular_transport

    Defects encompass improper sorting of cargo into transport carriers, vesicle budding, issues in movement of vesicles along cytoskeletal tracks, and fusion at the target membrane. Since the life cycle of the cell is a highly regulated and important process, if any component goes awry there is the possibility for deleterious effects.

  4. COPII - Wikipedia

    en.wikipedia.org/wiki/COPII

    SNARE, cargo, and other proteins are also needed for these processes to occur. Pre-budding complex (composed of Sar1-GTP and Sec23/24) recruits the flexible Sec13p/31p complex, characterized by polymerization of the Sec13/31 complex with other Sec13/31 complexes to form a cuboctahedron with a broader lattice than its Clathrin vesicle analog.

  5. COPI - Wikipedia

    en.wikipedia.org/wiki/COPI

    Electron micrograph of in vitro–formed COPI-coated vesicles. Average vesicle diameter at the membrane level is 60 nm. COPI is a coatomer, a protein complex [1] that coats vesicles transporting proteins from the cis end of the Golgi complex back to the rough endoplasmic reticulum (ER), where they were originally synthesized, and between Golgi compartments.

  6. Vesicular transport protein - Wikipedia

    en.wikipedia.org/wiki/Vesicular_transport_protein

    A vesicular transport protein, or vesicular transporter, is a membrane protein that regulates or facilitates the movement of specific molecules across a vesicle's membrane. [1] As a result, vesicular transporters govern the concentration of molecules within a vesicle.

  7. Coatomer - Wikipedia

    en.wikipedia.org/wiki/Coatomer

    COPI is a coatomer that coats the vesicles transporting proteins from the Golgi complex to the ER. [4] This pathway is referred to as retrograde transport. Before the COP I protein can coat vesicles on the Golgi membrane, it must interact with a small GTPase called ARF1 (ADP ribosylation factor). [5]

  8. Clathrin adaptor protein - Wikipedia

    en.wikipedia.org/wiki/Clathrin_adaptor_protein

    Adaptor protein (AP) complexes are found in coated vesicles and clathrin-coated pits. AP complexes connect cargo proteins and lipids to clathrin at vesicle budding sites, as well as binding accessory proteins that regulate coat assembly and disassembly (such as AP180, epsins and auxilin). There are different AP complexes in mammals.

  9. Exosome (vesicle) - Wikipedia

    en.wikipedia.org/wiki/Exosome_(vesicle)

    Exosomes are small extracellular vesicles that play a crucial role in cell-to-cell communication by transporting proteins, lipids, microRNAs, and functional mRNAs. Their potential in disease diagnostics, prognostics, and therapeutics has garnered significant interest in the biomedical field.
