A channel protein is a type of transmembrane protein that spans the cell membrane and provides a hydrophilic passageway for water and small, polar ions to move across the membrane by diffusion. Channel proteins are highly selective and only allow specific molecules or closely related molecules to pass through. WebChannel proteins. Channel proteins are water-filled pores; They allow charged substances (eg. ions) to diffuse through the cell membrane; The diffusion of these ions does not occur freely, most channel proteins are ‘gated’, meaning that part of the channel protein on the inside surface of the membrane can move in order to close or open the pore
