Targeted protein transport

Targeted protein transport is the biological process by which cells direct proteins to their specific locations inside or outside the cell. After proteins are made in the cell's factory (the ribosome), they need to reach the correct destination — such as the nucleus, mitochondria, or cell surface — to perform their functions. This process involves molecular signals and specialized transport systems that guide proteins along cellular pathways, ensuring they arrive accurately and efficiently. Proper targeting is essential for cell health, communication, and response to environmental signals.
