gate

 [gāt]
1. an electronic circuit that passes a pulse only when a signal (the gate pulse) is present at a second input.
2. a mechanism for opening or closing a protein channel in a cell membrane, regulated by a signal such as increased concentration of a neurotransmitter, change in electrical potential, or physical binding of a ligand molecule to the protein to cause a conformational change in the protein molecule.
3. to open and close selectively and function as a gate.

gate

(gāt),
1. To close an ion channel by electrical (for example, membrane potential) or chemical (for example, neurotransmitter) action.
See also: cardiac gating.
2. Action of a special nerve fiber to block the transmission of impulses through a synapse, for example, gating of pain impulses at synapses in the dorsal horns.
See also: cardiac gating.
3. A device that can be switched electronically to control the passage of a signal.
See also: cardiac gating.
4. To use a physiologic signal, such as an ECG, to trigger an event such as an x-ray exposure or to partition continuously collected data.
See also: cardiac gating.

Cell biology A structure composed of one or more proteins that regulate passage of ions through channels in the cell membrane; gates may be chemically regulated—by neurotransmitters—or voltage regulated—in response to a threshold level of depolarization
