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.

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.
Early endosomes (E - labeled for EGFR, 5 minutes after internalisation, and transferrin), late endosomes/MVBs (M) and lysosomes (L) are visible. Bar, 500 nm. Endosomes are a collection of intracellular sorting organelles in eukaryotic cells. They are parts of the endocytic membrane transport pathway originating from the trans Golgi network.
A vesicle is a relatively small, membrane-enclosed sac that stores or transports substances. [6] The cell membrane is a protective barrier that regulates what enters and leaves the cell. [ 7 ] There is also an organelle known as the Spitzenkörper that is only found in fungi, and is connected with hyphal tip growth.
Human Sar1A bound to GDP. The COPII coat consists of an inner layer – a flexible meshwork of Sar1, Sec23, and Sec24 – and an outer layer made of Sec13 and Sec31. [1] Sar1 resembles other Ras-family GTPases, with a core of six beta strands flanked by three alpha helices, and two flexible "switch domains".
Golgi cells can be found in the granular layer at various layers. [2] The Golgi cell is essential for controlling the activity of the granular layer. [3] They were first identified as inhibitory in 1964. [4] It was also the first example of an inhibitory feedback network in which the inhibitory interneuron was identified anatomically.
A small portion of an accessory protein binds specifically to part of AP-2 complex Protein phosphorylation allows specific interactions with a clathrin adaptor protein complex. The best characterized type of vesicle is the clathrin coated vesicle (CCV). The formation of a COPII vesicle at the endoplasmic reticulum and its transport to the Golgi ...
