Arrhythmogenic calmodulin E105A mutation alters cardiac RyR2 regulation leading to cardiac dysfunction in zebrafish
Da'as, Sahar I; Thanassoulas, Angelos; Calver, Brian L; Beck, Konrad; Salem, Rola; Saleh, Alaaeldin; Kontogianni, Iris; Al-Maraghi, Ali; Nasrallah, Gheyath K; Safieh-Garabedian, Bared; Toft, Egon; Nounesis, George; Lai, F Anthony; Nomikos, Michail... more authors ... less authors ( Wiley , 2019 , Article)Calmodulin (CaM) is a universal calcium (Ca )-binding messenger that regulates many vital cellular events. In cardiac muscle, CaM associates with ryanodine receptor 2 (RyR2) and regulates excitation-contraction coupling. ... -
