GOLT1A (Golgi transport 1A protein) is a member of the Golgi transport family that plays a role in regulating vesicular trafficking within cells, particularly in the Golgi apparatus. The Golgi apparatus is a key organelle responsible for processing, sorting, and modifying proteins and lipids from the endoplasmic reticulum (ER) before directing them to their final destinations. Although specific information on GOLT1A is limited, proteins in this family generally help mediate the movement of cargo vesicles between Golgi compartments and between the Golgi apparatus and other cellular locations.
