The 3/4- and 3/6-Subfamily Variants of α-Conotoxins GI and MI Exhibit Potent Inhibitory Activity against Muscular Nicotinic Acetylcholine Receptors

open access: yesMarine Drugs, 2021
α-Conotoxins GI and MI belong to the 3/5 subfamily of α-conotoxins and potently inhibit muscular nicotinic acetylcholine receptors (nAChRs). To date, no 3/4- or 3/6-subfamily α-conotoxins have been reported to inhibit muscular nAChRs.

Rationally designed α-conotoxin analogues maintained analgesia activity and weakened side effects [PDF]

open access: yes, 2019
A lack of specificity is restricting the further application of conotoxin from Conus bullatus (BuIA). In this study, an analogue library of BuIA was established and virtual screening was used, which identified high α7 nicotinic acetylcholine receptor ...

µ-Conotoxins as Leads in the Development of New Analgesics

open access: yesMolecules, 2010
Voltage-gated sodium channels (VGSCs) contain a specific binding site for a family of cone shell toxins known as µ-conotoxins. As some VGSCs are involved in pain perception and µ-conotoxins are able to block these channels, µ-conotoxins show considerable

Conotoxin Prediction: New Features to Increase Prediction Accuracy

open access: yesToxins, 2023
Conotoxins are toxic, disulfide-bond-rich peptides from cone snail venom that target a wide range of receptors and ion channels with multiple pathophysiological effects. Conotoxins have extraordinary potential for medical therapeutics that include cancer,

Differential Cav2.1 and Cav2.3 channel inhibition by baclofen and α-conotoxin Vc1.1 via GABAB receptor activation [PDF]

open access: yes, 2014
Neuronal Ca(v)2.1 (P/Q-type), Ca(v)2.2 (N-type), and Ca(v)2.3 (R-type) calcium channels contribute to synaptic transmission and are modulated through G protein-coupled receptor pathways. The analgesic. alpha-conotoxin Vc1.1 acts through.

Less is more: Design of a highly stable disulfide-deleted mutant of analgesic cyclic alpha-conotoxin Vc1.1 [PDF]

open access: yes, 2015
Cyclic alpha-conotoxin Vc1.1 (cVc1.1) is an orally active peptide with analgesic activity in rat models of neuropathic pain. It has two disulfide bonds, which can have three different connectivities, one of which is the native and active form.

The T-superfamily of Conotoxins [PDF]

open access: yesJournal of Biological Chemistry, 1999
Nous rapportons la découverte et la caractérisation initiale de la super-famille T des conotoxines. Huit peptides différents de la superfamille T de cinq espèces de Conus ont été identifiés ; ils partagent une séquence de signal consensuelle et un arrangement conservé de résidus de cystéine (- -CC- -CC-).

Identification and Characterization of a Novel Family of Cysteine-Rich Peptides (MgCRP-I) from Mytilus galloprovincialis [PDF]

open access: yes, 2015
We report the identification of a novel gene family (named MgCRP-I) encoding short secreted cysteine-rich peptides in the Mediterranean mussel Mytilus galloprovincialis.

Conotoxins that Confer Therapeutic Possibilities [PDF]

open access: yesMarine Drugs, 2012
Cone snails produce a distinctive repertoire of venom peptides that are used both as a defense mechanism and also to facilitate the immobilization and digestion of prey. These peptides target a wide variety of voltage- and ligand-gated ion channels, which make them an invaluable resource for studying the properties of these ion channels in normal and ...
