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.
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.
The protein is localized to the Golgi apparatus as well as co-localized with γ-tubulin or pericentrin (PCNT) in the centrosome, suggesting Proline and Serine-rich 3 is a centrosome component. 5, [10] In mammalian cells, the centrosome and Golgi apparatus are closely positioned during interphase and have a functional
The transitional ER gets its name because it contains ER exit sites. These are areas where the transport vesicles which contain lipids and proteins made in the ER, detach from the ER and start moving to the Golgi apparatus. Specialized cells can have a lot of smooth endoplasmic reticulum and in these cells the smooth ER has many functions. [6]

It is located on the trans face of the Golgi apparatus and is made up of cisternae. The cisternae play a crucial role in the packaging, modification, and transport functions for the cell overall. The proteins and polysaccharides that get processed here within the cisterna will then be sent to their specified locations. [3]
Golgi apparatus: The primary function of the Golgi apparatus is to process and package the macromolecules such as proteins and lipids that are synthesized by the cell. Lysosomes and peroxisomes: Lysosomes contain digestive enzymes (acid hydrolases). They digest excess or worn-out organelles, food particles, and engulfed viruses or bacteria.
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).
