excitatory extracellular ligand-gated ion channel activity

id: GO:0005231
name: excitatory extracellular ligand-gated ion channel activity
namespace: molecular_function
type: go
obsolete: False

Description: Catalysis of the transmembrane transfer of an ion by a channel that opens when a specific extracellular excitatory ligand has been bound by the channel complex or one of its constituent parts. Excitatory ligands, such as acetylcholine or glutamate, open cation-selective channels.
