Previously unknown protein critical to heart muscle contraction identified.


Heart muscle is activated by ionized calcium, with the signaling pathway utilising allosteric mechanisms in the thin filament. Knowledge about the structure-function relationship among proteins in this filament is critical in understanding the physiology and pathology of the cardiac function and disease; however it remains obscure.  Now, researchers at UT Southwestern have identified a previously unknown protein, which they have
