Receptors embedded in the membrane of the Golgi body bind specific cargo (such as dopamine) on the lumenal side of the vesicle. These cargo receptors then recruit a variety of proteins including other cargo receptors and coat proteins such as clathrin, COPI and COPII. As more and more of these coating proteins come together, they cause the ...
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.

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. In order for the transport vesicle to accurately undergo a fusion event, it must first recognize the correct target membrane then fuse with that membrane.
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.
Golgi apparatus (also called the Golgi body, Golgi complex, or dictyosome), an organelle in a eukaryotic cell; Golgi tendon organ, a proprioceptive sensory receptor organ; Golgi's method or Golgi stain, a nervous tissue staining technique; Golgi alpha-mannosidase II, an enzyme; Golgi cell, a type of interneuron found in the cerebellum
Molecules are also transported to endosomes from the trans Golgi network and either continue to lysosomes or recycle back to the Golgi apparatus. Endosomes can be classified as early, sorting, or late depending on their stage post internalization. [1] Endosomes represent a major sorting compartment of the endomembrane system in cells. [2]
The different types of endocytosis. Endocytosis is a cellular process in which substances are brought into the cell. The material to be internalized is surrounded by an area of cell membrane, which then buds off inside the cell to form a vesicle containing the ingested materials.
