carrier protein


Also found in: Dictionary, Thesaurus, Encyclopedia, Wikipedia.

carrier protein

a multiunit transmembrane protein that possesses specific binding sites of a particular molecule and transports that substance across the cell membrane. It does so by reversibly altering its conformation after binding occurs and after resuming its original molecular conformation after transporting and releasing the substance on the other side of the membrane.
See also: uniport, symport, antiport.

binding protein

A generic term for a protein that reversibly binds to various small molecules, including amino acids, sugars, inorganic ions, vitamins and other molecules.

carrier protein

1. A protein that elicits an immune response when coupled with a hapten.
2. A membrane protein for facilitated diffusion of a specific substance into a cell.
