Abstract
Transmitter-gated ion channels are multisubunit membrane-spanning receptors that serve as rapid signal transduction devices regulating the flow of cations or anions through the cell membrane. Cell type—specific flexibility in neurotransmission is accomplished by a multiplicity of channel variants based on the combinatorial assembly of structurally related subunits. The heteromeric subunit structure also permits synaptic plasticity by changes in subunit composition and subunit-specific posttranslational modification. In addition, receptor heterogeneity offers the potential for cell type-specific drug targeting.
