Calcineurin: From Activation To Inhibition, Erik C. Cook
Theses and Dissertations--Molecular and Cellular Biochemistry
Calcineurin is a Ser/Thr phosphatase whose function is implicated in critical physiological processes such as immune system activation, fetal heart development, and long-term depression in neurons. Calcineurin has been implicated in the progression of Alzheimer’s disease and cardiac hypertrophy. It is not well understood how calcineurin is activated on a molecular level by Ca2+ and its activating protein calmodulin. Previous data from our lab show that calmodulin interaction induces the folding of the intrinsically disordered regulatory domain of calcineurin in two discrete and distant regions into α-helical conformations and that this folding is critical for complete activation of calcineurin. …
