Grouped By:  Matching UniProtKB accession

UniProtKB description:  This bird and reptile-specific postsynaptic neurotoxin inhibits the chick muscle alpha-1-beta-1-gamma-delta (CHRNA1-CHRNB1-CHRNG-CHRND) nicotinic acetylcholine receptor (nAChR) 100-fold more compared with the mouse receptor. In vivo, produces rapid flaccid paralysis, dyspnea and increased respiratory rate in geckos. At sublethal doses geckos were immobilized for up to three days and then recovered. Chicks injected with lethal doses showed rapid onset of inactivity, dyspnea and neck droop, and no extended paralysis with survival was seen.
