Abstract:
Calcineurin is an evolutionarily conserved, ubiquitously expressed protein phosphatase that serves as a major effector of Ca(2+) signals, regulating diverse biological processes such as gene expression, tissue differentiation, immune responses, and neural plasticity. The following method describes how to monitor real-time calcineurin activity in cultured mammalian cells using a fluorescence resonance energy transfer (FRET)-based activity reporter.
