Phosphatidylinositol 4,5-Bisphosphate Increases Ca(2+) Affinity of Synaptotagmin-1 by 40-fold
Synaptotagmin-1 is the main Ca(2+) sensor of neuronal exocytosis. It binds to both Ca(2+) and the anionic phospholipid phosphatidylinositol 4,5-bisphosphate (PIP(2)), but the precise cooperativity of this binding is still poorly understood. Here, we used microscale thermophoresis to quantify the coo...
