Ca2+ influx in cardiomyocytes is regulated by the activity of the heteromeric L-type voltage-activated CaV 1.2 channel. A complex network of interactions between the different prote ins forming the ion channel determines the total Ca2+ influx. Alterations in the biophysical and biochemical properties or in the biogenesis in any of these proteins can lead to serious disturbances in the cardiac rhythm. We have investigated the multi-subunit nature of the channel complex by ho mology with the three-dimensional structure of the closely related CaV1.1 channel. The architectural map identifies precise interaction loci between the different subunits and paves the way for elucidating the mechanistic basis for the regulation of Ca2+ balance in cardiac myocytes under physiol ogical and pathological conditions. \n DTSTART:20200221T160000Z DTEND:20200221T170000Z LOCATION:Room 1034\, McIntyre Medical Building\, CA\, QC\, Montreal\, H3G 1 Y6\, 3655 promenade Sir William Osler SUMMARY:Seminar - Regulation of calcium channel activity in cardiomyocytes : what is the role of auxiliary subunits?
