The venom contains hundreds of specific peptide toxins, many of which are selective for ion channels or receptors. omega-Conotoxin GVIA. We have examined the effects of various manipulations aimed at elucidating the effects of ?-conotoxin particularly on K(+) stimulated (45)Ca(2+) influx and endogenous acetylcholine (ACh) release. An important trigger for exocytosis is the calcium influx via alpha-latrotoxin-induced channels in biological membranes. Conotoxins. Conotoxine 3.Wirkungsweise Gliederung 1.

Nicotinic acetylcholine receptors (nAChRs) expressed by dopaminergic (DA) neurons have long been considered as potential therapeutic targets for the treatment of several neuropsychiatric diseases, including nicotine and cocaine addiction or Parkinson's disease. Conotoxins are hypervariable even within the same species; the genes that encode them do not act endogenously,[3] and thus are less conserved and more likely to experience gene duplication events and nonsynonymous mutations which lead to the development of novel functions. alpha-Conotoxin M I | C58H88N22O17S4 | CID 25081090 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological .
