Alpha-conotoxin AuIC

Gene
N/A
Organism
Conus aulicus (Princely 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. This toxin blocks mammalian nAChR alpha-3/beta-4 subunits.
