PKA phosphorylates Myosin Binding Protein-C (MyBP-C) and troponin I (TnI) within the cardiac myofibril. TnI would be the inhibitory element from the trimeric troponin molecule which makes up the Ca2+-change of the contractile apparatus. TnI binds to TnC when Ca2+ is bound to TnC, although in the absence of Ca2+, https://jimmyh665ylw0.blog-mall.com/profile
