    A transport protein is a type of protein that helps certain substances to cross to the membrane. This is done by a process known as facilitated diffusion. There are 3 types of these: membrane transport protein, vesicular transport protein and carrier protein.

    A membrane transport protein is a protein involved in the movement of ions, small molecules such as protein across the biological membrane. They are integral proteins because they exist within and span the membrane across which they transport substances. These types of proteins assist in the movement of substances by facilitated diffusion or active transport. A vesicular transport protein is a protein which regulates or facilitates the movement by vesicles of the contents of the cell.
