Quercetin interacts with calmodulin, a calcium regulatory protein.
Quercetin was found to interact with the Ca2+-calmodulin complex, suggesting that it may act as a calmodulin antagonist in vivo to inhibit calmodulin-dependent phenomena caused by biologically active agents, including tumor promoters.
