  2. Protein targeting - Wikipedia

    en.wikipedia.org/wiki/Protein_targeting

    Protein targeting or protein sorting is the biological mechanism by which proteins are transported to their appropriate destinations within or outside the cell. [ 1 ] [ 2 ] [ note 1 ] Proteins can be targeted to the inner space of an organelle , different intracellular membranes , the plasma membrane , or to the exterior of the cell via secretion .

  3. Cisterna - Wikipedia

    en.wikipedia.org/wiki/Cisterna

    As well as the location of the cis and trans Golgi network. The cis Golgi network is the first step in the cisternal structure of a protein being packaged, while the trans Golgi network is the last step in the cisternal structure when the vesicle is being transferred to either the lysosome, the cell surface or the secretory vesicle.

  4. Golgi apparatus - Wikipedia

    en.wikipedia.org/wiki/Golgi_apparatus

    The Golgi apparatus (/ ˈ ɡ ɒ l dʒ i /), also known as the Golgi complex, Golgi body, or simply the Golgi, is an organelle found in most eukaryotic cells. [1] Part of the endomembrane system in the cytoplasm , it packages proteins into membrane-bound vesicles inside the cell before the vesicles are sent to their destination.

  5. Intracellular transport - Wikipedia

    en.wikipedia.org/wiki/Intracellular_transport

    Outbound proteins from the endoplasmic reticulum will bud off into transport vesicles that travel along the cell cortex to reach their specific destinations. [3] Since the ER is the site of protein synthesis, it would serve as the parent organelle, and the cis face of the golgi, where proteins and signals are received, would be the acceptor.

  6. Post-translational modification - Wikipedia

    en.wikipedia.org/wiki/Post-translational...

    Then the protein passes through the golgi apparatus, where it is packaged into a vesicle. In the vesicle, more parts are cut off, and it turns into mature insulin. In molecular biology, post-translational modification (PTM) is the covalent process of changing proteins following protein biosynthesis. PTMs may involve enzymes or occur spontaneously.

  7. Sortilin 1 - Wikipedia

    en.wikipedia.org/wiki/Sortilin_1

    As a sorting receptor on the cell surface and on the endoplasmic reticulum-Golgi apparatus within the cell, sortilin is involved in the transport of a wide variety of intracellular proteins between the trans-Golgi network, endosome, lysosome, and secretory granules, as well as the plasma membrane. [8]

  8. Clathrin adaptor protein - Wikipedia

    en.wikipedia.org/wiki/Clathrin_adaptor_protein

    There are different AP complexes in mammals. AP1 is responsible for the transport of lysosomal hydrolases between the trans-Golgi network, and endosomes. [6] AP2 adaptor complex associates with the plasma membrane and is responsible for endocytosis. [7] AP3 is responsible for protein trafficking to lysosomes and other related organelles. [8]

  9. Clathrin - Wikipedia

    en.wikipedia.org/wiki/Clathrin

    Coat-proteins, like clathrin, are used to build small vesicles in order to transport molecules within cells. The endocytosis and exocytosis of vesicles allows cells to communicate, to transfer nutrients, to import signaling receptors, to mediate an immune response after sampling the extracellular world, and to clean up the cell debris left by ...
