WebThere are two distinctive features of ion channels that differentiate them from other types of ion transporter proteins: The rate of ion transport through the channel is very high (often 10 6 ions per second or greater).; Ions pass through channels down their electrochemical gradient, which is a function of ion concentration and membrane potential, "downhill", … Web2.3 Other Classification. It can also be classified according to the position of its N-terminal and C-terminal domains. Type I transmembrane proteins are anchored to the lipid membrane by stop-transport anchoring sequences, and their N-terminal domains target the endoplasmic reticulum cavity during synthesis.
