Selective inhibitor of Ca2+-calmodulin-dependent protein phosphatase (calcineurin) (IC50 ~ 10 μM). Does not inhibit PP1, PP2A or CaM kinase II (IC50 > 100 mM).
Calcineurin substrate (TFA) is a polypeptide derived from the regulatory RII subunit of camp-dependent protein kinase.Calcineurin substrate (TFA) can be used to determine the activity of Calcineurin.
