ALPK3 knockout models severe cardiomyopathy in mice; leaves open targeted therapies for human pediatric disease.
ALPK3 is essential for neonatal and adult cardiac function, acting as a scaffold protein at the M-band to regulate thick filament protein turnover, with its loss leading to fatal or progressive cardiomyopathy.
Feng et al. (2025) studied Cardiomyopathy. ALPK3 global knockout was evaluated on Mortality. Global knockout of ALPK3 in mice leads to dilated cardiomyopathy, with approximately 75% of germline mutant mice dying within 1 month.
