The rapid and reversible association of phosphofructokinase with myocardial membranes during myocardial ischemia.


Myocardial calcium-independent phospholipase A2 (PLA2) activity is mediated by a 400 kDa catalytic complex comprised of a tetramer of phosphofructokinase (PFK) and a 40 kDa catalytic subunit [1,2]. During myocardial ischemia, calcium-independent PLA2 activity rapidly and reversibly translocates from the cytosol to a membrane-associated compartment where it… (More)
