WebWhen triggered by internal or external stimuli, cells initiate PCDs through evolutionary conserved regulatory mechanisms. Actin, as a multifunctional cytoskeleton protein that forms microfilament, its integrity and dynamics are essential for a variety of cellular processes (e.g., morphogenesis, membrane blebbing and intracellular transport). WebSimilarly, we previously found that stimulation of cytoskeleton-bound glycolytic enzymes exerted by insulin, EGF, or Ca 2+, was also calmodulin mediated. The present and previous results suggest that the rapid, Ca 2+ -calmodulin-mediated increase in cytoskeleton-bound glycolytic enzymes, may be a general mechanism in the cell, in signal transduction of …
