Solution structure of ω-conotoxin MVIIA using 2D NMR spectroscopy

open access: yes, 1995
The solution structure of ω-conotoxin MVIIA (SNX-111), a peptide toxin from the fish hunting cone snail Conus magus and a high-affinity blocker of N-type calcium channels, was determined by 2D NMR spectroscopy.

A Transcriptomic Survey of Ion Channel-Based Conotoxins in the Chinese Tubular Cone Snail (Conus betulinus)

open access: yesMarine Drugs, 2017
Conotoxins in the venom of cone snails (Conus spp.) are a mixture of active peptides that work as blockers, agonists, antagonists, or inactivators of various ion channels.

Monoclonal antibodies against the presynaptic calcium channel antagonist ω-conotoxin GVI A from cone snail poison

open access: yes, 1990
Monoclonal antibodies have been prepared against co-conotoxin GVI A, a peptide isolated from marine snails of the genus Conus (Conus geographus and Conus magus).

Identifying key amino acid residues that affect alpha-conotoxin AuIB inhibition of alpha3beta4 nicotinic acetylcholine receptors [PDF]

open access: yes, 2013
Background: -Conotoxin AuIB interacts with 34 nAChRs and GABA(B) receptors, but structural determinants of these interactions are unknown. Results: Using alanine scanning mutagenesis and molecular dynamics, we identified residues crucial for AuIB34 nAChR

MicroO-conotoxin MrVIA inhibits mammalian sodium channels, but not through site I

open access: yes, 1996
1. A 31-amino-acid peptide from the venom of the snail-hunting species Conus marmoreus, microO-conotoxin MrVIA, inhibits mammalian voltage-gated sodium channels through a novel mechanism distinct from saxitoxin, tetrodotoxin, or mu-conotoxin. 2.

‘Messy’ Processing of χ-conotoxin MrIA Generates Homologues with Reduced hNET Potency

open access: yesMarine Drugs, 2019
Integrated venomics techniques have shown that variable processing of conotoxins from Conus marmoreus resulted in a dramatic expansion in the number of expressed conotoxins. One conotoxin from C.

Effects of Predator-Prey Interactions on Predator Traits: Differentiation of Diets and Venoms of a Marine Snail

open access: yesToxins, 2019
Species interactions are fundamental ecological forces that can have significant impacts on the evolutionary trajectories of species. Nonetheless, the contribution of predator-prey interactions to genetic and phenotypic divergence remains largely unknown.

Three-Dimensional Solution Structure of ω-Conotoxin TxVII, an L-Type Calcium Channel Blocker,

open access: yes, 2016
We determined the three-dimensional structure of ω-conotoxin TxVII, a 26-residue peptide that is an L-type calcium channel blocker, by 1H NMR in aqueous solution.
