The Golgi apparatus, which participates in glycosylation and transport of proteins and lipids in the secretory pathway, consists of a series of stacked cisternae (flattened membrane sacs). Interactions between the Golgi and microtubules are thought to be important for the reorganization of the Golgi after it fragments during mitosis. [ 6 ]
Animal Farm is a satirical allegorical novella, in the form of a beast fable, [1] by George Orwell, first published in England on 17 August 1945. [2] [3] It tells the story of a group of anthropomorphic farm animals who rebel against their human farmer, hoping to create a society where the animals can be equal, free, and happy.
The Golgi matrix is a collection of proteins involved in the structure and function of the Golgi apparatus. [1] [2] [3] The matrix was first isolated in 1994 as an amorphous collection of 12 proteins that remained associated together in the presence of detergent (which removed Golgi membranes) and 150 m M NaCl (which removed weakly associated proteins). [4]
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.
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.
Squealer is a fictional character, a pig, in George Orwell's 1945 novel Animal Farm.He serves as second-in-command to Napoleon and is the farm's minister of propaganda.He is described in the book as an effective and very convincing orator and a fat porker.
Furin is enriched in the Golgi apparatus, where it functions to cleave other proteins into their mature/active forms. [14] Furin cleaves proteins just downstream of a basic amino acid target sequence (canonically, Arg-X-(Arg/Lys) -Arg'). In addition to processing cellular precursor proteins, furin is also used by a number of pathogens.
The Golgi apparatus (also known as the Golgi body and the Golgi complex) is composed of separate sacs called cisternae. Its shape is similar to a stack of pancakes. The number of these stacks varies with the specific function of the cell. The Golgi apparatus is used by the cell for further protein modification.
