Interaction of alpha-conotoxin ImII and its analogs with nicotinic receptors and acetylcholine-binding proteins: additional binding sites on Torpedo receptor.

25 Aug 2009 alpha-Conotoxins interact with nicotinic acetylcholine receptors (nAChRs) and acetylcholine-binding proteins (AChBPs) at the sites for agonists/competitive antagonists. alpha-Conotoxins blocking muscle-type or alpha7 nAChRs compete with ... Read more...

Expression of Prothymosin alpha during the spermatogenesis of the spotted ray Torpedo marmorata.

16 May 2009 In this study, we show that Prothymosin alpha (Ptma), a small, unfolded, negatively charged protein, is present in the cartilaginous fish Torpedo marmorata. The ptma gene is functional and peculiarly controlled during the male spermatogenesis of T. ... Read more...

A lipid-dependent uncoupled conformation of the acetylcholine receptor.

6 Apr 2009 Lipids influence the ability of Cys-loop receptors to gate open in response to neurotransmitter binding, but the underlying mechanisms are poorly understood. With the nicotinic acetylcholine receptor (nAChR) from Torpedo, current models suggest that ... Read more...
