Over 90% of a newly synthesized T-cell receptor is destroyed before it ever reaches the cell surface, highlighting the rigorous quality control and sorting required for protein transport. Understanding how do proteins transport is crucial to comprehending the fundamental logistics of a living cell, which uses intricate networks and molecular machinery to move these critical molecules to their proper destinations inside and outside of cellular membranes.

Remarkably, proteins constitute about 50% of the dry weight of a typical cell, performing countless tasks, with one of the most critical being the facilitated movement of substances across membranes. This process, known as protein transport, is central to nutrient delivery, ensuring that carbohydrates, fats, and minerals reach the cells that need them.
