Description

General description

Corresponds to a C-terminal domain (residues 457-482) of the calmodulin-binding domain of calcineurin. Specific calcineurin inhibitor. Does not inhibit CaM kinase II, protein phosphatase I or 2A. Inhibits Mn²⁺-stimulated calcineurin activity (IC₅₀ = 10 µM using ³²P myosin light chain as a substrate) but has no effect on Ni²⁺-stimulated activity.

Specific calcineurin inhibitor. Corresponds to the C-terminal domain (residues 457-482) of the calmodulin-binding domain of calcineurin (PP2B). Inhibits Mn²⁺-stimulated calcineurin activity (IC₅₀ = 10 µM using ³²P-myosin light chain as a substrate) but has no effect on Ni²⁺-stimulated enzyme activity. Does not inhibit CaM kinase II, protein phosphatase 1 or 2A.
