The Golgi Apparatus Organization of the Golgi: The Golgi apparatus functions in protein processing and sorting as well as in the synthesis of lipids and polysaccharides. TEDx Talks Recommended for you. Lecture Content Introduction The secretory pathway in eukaryotic cells is used to send proteins and lipids to the plasma membrane and certain membrane-bound organelles and to release material outside the cell. Cells not only release material to the external environment but they also take up material from outside the plasma membrane through endocytosis. The GTPase dynamin catalyzes the pinching off reaction.

    Cartoon showing how cargo receptors mediate traffic by cycling.
    Subsequent interactions between transmembrane proteins on vesicle and target membranes lead to membrane fusion. How are proteins targeted to these three different fates?

The digestive enzymes produced by the acinar cells of the pancreas are stored in dense core granules called zymogen granules and are released into the duct leading to the gut following feeding.

    In constitutive secretion proteins are secreted from a cell continuously, regardless of external factors or signals.

    The trans Golgi network is a major sorting centre. Some proteins are sorted into secretory vesicles that store these proteins until the cell is signaled to release them. The digestive enzymes produced by the acinar cells of the pancreas are stored in dense core granules called zymogen granules and are released into the duct leading to the gut following feeding.

    The secretory pathway refers to the endoplasmic reticulum, Golgi Moreover, different proteins may live only in the secretory pathway or only in the cytosol. the parts of membrane proteins that stick out on the cytosolic side.
    The unfolded protein response pathway monitors the amount of unfolded protein in the ER and regulates cellular activities to maintain appropriate protein folding capacity.

Targeting Vesicles to Correct Compartment Two sets of proteins appear to help vesicles fuse with the correct target membrane. Protein glycosylation within the Golgi: The N -linked oligosaccharides added to proteins in the ER are modified within the Golgi. Growing polypeptide chains are then translocated into the ER through protein channels and released into the ER lumen by cleavage of the signal sequence.

    Dense core secretory granules dock at the cell surface and release their contents when they are stimulated to do so. Sar1-GTP recruits two other sets of proteins that make up the vesicle coat: the SecSec24 complex that binds to cargo proteins and the SecSec31 complex that helps drive the formation of the vesicle. In polarized cells, proteins are specifically targeted to the apical and basolateral domains of the plasma membrane.

    External signals trigger the removal of the pairing inhibition, allowing the vesicles to fuse with the plasma membrane. Waves: Light, Sound, and the nature of Reality - Duration:
