Gene
N/A
Organism
Conus quercinus (Oak cone)
Status
Reviewed-Annotation score: -Protein uncertaini

Functioni

Alpha-conotoxins act on postsynaptic membranes, they bind to the nicotinic acetylcholine receptors (nAChR) and thus inhibit them.By similarity

Miscellaneous

The mature peptide contains 3 cysteine residues.

Caution

Could be the product of a pseudogene.Curated
