Calcium-transporting ATPase ATP2A2, also known as SERCA2a, is a critical ATPase responsible for Ca2+ re-uptake during excitation–contraction (E-C) coupling. Impaired Ca2+ uptake resulting from decreased expression and reduced activity of SERCA2a is a hallmark of heart failure
Roger Hajjar and co-workers have demonstrated that SUMOylation is essential for preserving the stability and activity of SERCA2a and that levels of SUMO1 are decreased in failing hearts. They also show in a mouse model of heart failure that gene delivery of SUMO1 can restore heart function to the same degree as delivery of SERCA2a, pointing to SUMO1 as a potential therapeutic candidate for treating heart failure.
