Term Name: | protein retention in Golgi apparatus |
---|---|
Synonyms: | maintenance of protein location in Golgi apparatus, protein-Golgi retention, retention of protein in Golgi |
Definition: | The retention of proteins within the Golgi apparatus. Golgi-localized carbohydrate-modifying enzymes have a short N-terminal domain that faces the cytosol, a single transmembrane alpha helix, and a large C-terminal domain that faces the Golgi lumen and that contains the catalytic site. How the membrane-spanning alpha helix in a Golgi enzyme causes its localization and prevents its movement to the plasma membrane is not known. |
