Despite recently advanced medical therapies, heart failure is one of the leading risks of death in developed nations. T-tubular L-type Ca2+ channels (LTCC) in ventricular myocytes play a crucial role in cardiac excitation-contraction coupling. Decreased basal activity of t-tubular LTCC is involved in cardiac disfunction. We recently found that basal activity of LTCC is supported by casein kinase 2 (CK2). Here, I examined the molecular mechanisms underlying regulation of basal LTCC activity by CK2. In the result, I found that CK2a'b determines the basal activity of cardiac LTCC.
