extracellularly glycine-gated chloride channel activity
Definition
Target type: molecularfunction
Enables the transmembrane transfer of a chloride ion by a channel that opens when glycine is bound by the channel complex or one of its constituent parts on the extracellular side of the plasma membrane. [GOC:mtg_transport, ISBN:0815340729]
Extracellularly glycine-gated chloride channel activity refers to the function of a specific type of ion channel found in the cell membrane. This channel is activated by the neurotransmitter glycine, which binds to specific receptor sites on the extracellular surface of the channel. When glycine binds, it triggers a conformational change in the channel protein, opening a pore that allows chloride ions (Cl-) to flow across the cell membrane. This flow of chloride ions changes the electrical potential across the membrane, leading to the generation of an electrical signal within the cell. This process is crucial for neurotransmission, particularly in the central nervous system, as it is involved in inhibitory signaling. Glycine-gated chloride channels are responsible for mediating fast inhibitory synaptic transmission in the spinal cord and brainstem. They play a vital role in regulating neuronal excitability, motor control, sensory perception, and other important physiological functions. Dysfunction of these channels can lead to various neurological disorders, such as epilepsy and spasticity.'
