41Stretch-activated ion channel — Stretch activated or stretch gated ion channels are ion channels which open their pores in response to mechanical deformation of a neuron s plasma membrane. Stretch activated channels were first observed in chick skeletal muscles by Falguni… …
42P-type calcium channel — calcium channel, voltage dependent, P/Q type, alpha 1A subunit Identifiers Symbol CACNA1A Alt. symbols Cav2.1, CACNL1A4, SCA6, MHP1, MHP IUPHAR Cav2.1 …
43L-type calcium channel — The L type calcium channel is a type of voltage dependent calcium channel. L stands for long lasting referring to the length of activation. Like the others of this class, the α1 subunit is the one that determines most of the channel s properties …
44Membrane channel — A family of biological membrane proteins which allow the passive movement of ions (ion channels), water (aquaporins) or other solutes to passively pass through the membrane down their electrochemical gradient. References Molecular Biology of the… …
45HCN channel — Hyperpolarization activated cyclic nucleotide gated (HCN) channels are proteins that serve as ion channels across the plasma membrane of heart and brain cells [Luthi A, McCormick DA. 1998. Neuron. H current: properties of a neuronal and network… …
46Open channel block — refers to the idea that various drugs and other small molecules produce their effects by entering and plugging open ion channels. The idea was first proposed by Clay Armstrong to explain the action of tetraethylammonium ions, and other similar… …
47sodium-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… …
48Cyclic nucleotid gated channel — Protéine canal HCN Pour les articles homonymes, voir HCN. Les protéines canal HCN (de l anglais Hyperpolarisation activated Cylic Nucleotid modulated Cation Non selective Channel, c’est à dire canal activé par l hyperpolarisation, modulé par les… …
49Epithelial 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… …
50ion channel — A transmembrane pore that presents a hydrophilic channel for ions to cross a lipid bilayer down their electrochemical gradients. Some degree of ion specificity is usually observed, and typically a million ions per second may flow. Channels may be …
