Epithelial sodium channel — The epithelial sodium channel (short: ENaC, also: sodium channel non neuronal 1 (SCNN1) or amiloride sensitive sodium channel (ASSC)) is a membrane bound ion channel that is permeable for Li+ ions, protons and especially Na+ ions. It is a… … Wikipedia
epithelial sodium channel — (ENaC) a non gated epithelial cell membrane channel through which sodium diffuses down its concentration gradient into the cell, leading to the absorption of water through water channels. Its functions include resorption of salt and water in… … Medical dictionary

Channel blocker — A channel blocker (CB) or ion channel blocker (ICB) is a type of drug which binds inside the pore of a specific type of ion channel and blocks the flow of ions through it, resulting in an alteration of the electrochemical gradient of the cell… … Wikipedia
sodium-potassium ATPase — A major transport protein of the plasma membrane. A multi unit enzyme, it moves 3 sodium ions out of the cell, and 2 potassium ions in, for each ATP hydrolyzed. The sodium gradient established is used for several purposes (see facilitated… … Dictionary of molecular biology
