Subcellular trafficking is a research area focused on the movement of biomolecules within cells. This process involves the sorting, transport, and delivery of various molecules including proteins, lipids, and other cellular components to specific locations within the cell. Subcellular trafficking is crucial for maintaining cellular function, as it ensures that molecules are directed to the correct organelles and compartments within the cell. This research area explores the mechanisms and regulation of subcellular trafficking, as well as its role in various cellular processes such as signal transduction, metabolism, and disease.
