AP-1 complex

The AP-1 complex is a protein assembly that helps transport certain molecules within cells. Specifically, it directs proteins to their correct locations by packaging them into tiny bubbles called vesicles. AP-1 is involved mainly in moving proteins from the Golgi apparatus—a cell’s sorting center—to other parts, like the cell membrane or endosomes. This process is crucial for maintaining cell function and communication. Think of AP-1 as part of a logistics team inside the cell, ensuring proteins are delivered accurately and efficiently to where they are needed.
