Description

General description

Calyculin A is derived from the marine sponge Discodermia calyx. It corresponds to a molecular weight of 1008 Da.

Application

Calyculin A from Discodermia calyx has been used:

• as an inhibitor of serine-threonine protein phosphatase 2A
• as an inhibitor of cyclin D1 phosphatase in human breast cancer cells
• as an inhibitor of protein phosphatase 2A (PP2A) and PP1 in mouse melanoma cell lines B16-F0 cells

Biochem/physiol Actions

Calyculin A from Discodermia calyx binds to the okadaic acid receptors. In smooth muscles, it activates calcium channel. Calyculin A regulates protein phosphorylation thereby regulating capacitation in sperm. It enhances phosphorylation of nuclear factor κ-light-chain-enhancer of activated B cells (NF-κB) and apoptosis.

Inhibitor of protein phosphatases types 1 and 2A; marine toxin, potent tumor promotor.
