Alpha-conotoxin Lp1.1

Gene
N/A
Organism
Conus leopardus (Leopard cone)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at protein leveli

Functioni

Alpha-conotoxins act on postsynaptic membranes, they bind to the nicotinic acetylcholine receptors (nAChR) and thus inhibit them. Synthetic peptide inhibits alpha-6/alpha-3/beta-2 and alpha-3/beta-2 nicotinic acetylcholine receptors and causes uncoordinated movement when intramuscularly injected into goldfish.1 Publication
