Gene Names
Taxonomy Paraponera clavata

General annotation

Function Blocks nicotinic synaptic transmission in insect CNS and affects voltage-dependent sodium channels. It is a strong, but very slowly acting agonist for smooth muscles and its blocks synaptic transmission in the insect CNS in a concentration- dependent manner and depolarizes giant interneurons. Also affects neuromuscular transmission in rat tissue.
Subcellular location Secreted.
