Activity

Neurotoxin
FUNCTION: Insecticidal neurotoxin that reversibly inhibits the N-methyl-D-aspartate (NMDA)-subtype of ionotropic glutamate receptor (GRIN) and inhibits inactivation of insect sodium channels (Nav). In vivo, is highly toxic to insects. {ECO:0000250|UniProtKB:P59367}.

Target

voltage-gated sodium channel (Nav) glutamate receptor
