Inherited Ventricular Arrhythmias: The Role of the Multi-Subunit Structure of the L-Type Calcium Channel Complex.
Briot J, Tétreault MP, Bourdin B, Parent L. Briot J, et al. Adv Exp Med Biol. 2017;966:55-64. doi: 10.1007/5584_2016_186. Adv Exp Med Biol. 2017. PMID: 28315127 Review.
Ca(2+) influx in cardiomyocytes is regulated by the activity of the heteromeric L-type voltage-activated Ca(V)1.2 channel. A complex network of interactions between the different proteins forming the ion channel supports the kinetics and the activation gating of the Ca(2+) …

Double mutant cycle analysis identified a critical leucine residue in the IIS4S5 linker for the activation of the Ca(V)2.3 calcium channel.
Wall-Lacelle S, Hossain MI, Sauvé R, Blunck R, Parent L. Wall-Lacelle S, et al. J Biol Chem. 2011 Aug 5;286(31):27197-205. doi: 10.1074/jbc.M111.237412. Epub 2011 Jun 7. J Biol Chem. 2011. PMID: 21652722 Free PMC article.
., and Parent, L. (2007) J. Biol. Chem. 282, 27944-27952). By analogy with K(V) channels, we tested the hypothesis that channel activation involves electromechanical coupling between S6 and the S4S5 linker in Ca(V)2.3. ...
