= Uniporter
{wiki=Uniporter}
A uniporter is a type of membrane transport protein that facilitates the transport of a specific molecule across a biological membrane in one direction. Unlike symporters and antiporters, which move multiple substances simultaneously in opposite or the same directions, uniporters allow only one type of substrate to pass through the membrane at a time. This process typically occurs down the substrate's concentration gradient, making it a form of facilitated diffusion.
