Input (English): A defective enzyme in this structure is the cause of I-cell disease. Transport from this structure is regulated by GGA1, which binds to ADP ribosylation factor 1, while transport to this structure is inhibited by brefeldin A. In sperm, this structure develops into another structure which uses hyaluronidase and acrosin to facilitate sperm-egg binding. This precursor to the acrosome is the site where addition of (*) N-acetylglucosamine to serine and threonine residues and other forms of O-linked glycosylation takes place. This organelle receives COP2 coated vesicles at its cis face, and it consists of a series of stacks termed cisternae. For 10 points, name this organelle which packages and distributes proteins incoming from the endoplasmic reticulum and is named for its Italian discoverer.
Output (English): Science
