- Definition ion channel receptor which has to be bound by a ligand (i.e. a molecule that binds another specific molecule, in some cases, delivering a signal in the process) or a signal molecule for the channel to open its pores [ IATE:1149329/EN ] Reference COM-Terminology Coordination, based on: 1) J.E.

- Comment Such specific ligands or signal molecules are hormones, neurotransmitters, or local hormones. Such channels are primarily responsible for impulse initiation = initial depolarization of an excitable cell such as neurons, muscle cells, and gland cells; they can contribute to either depolarization, repolarization or hyperpolarization of a cell, depending on circumstances.
