Opis ogólny
An ionophore-like polyether derivative of a C38 fatty acid compound isolated from dinoflagellates that have fed on the marine sponge Halinchrondria okadai. It is a potent non-comepetitive, reversible inhibitor of serine/threonine-specific protein phosphatases 1 (PP1, IC50 = 10-15 nM, rabbit skeletal muscle, catalytic subunit) and 2A (PP2A, IC50 = 0.1 nM, rabbit skeletal muscle, catalytic subunit). It has only a trivial effect on protein phosphatase 2B (IC50 = 5 µM), a Ca2+/calmodulin-dependent enzyme, while PP2C, a Mg2+ dependent enzyme, is unaffected. Okadaic acid has no significant effect on the activities of tyrosine phosphatases, alkaline phosphatase, acid phosphatase, and inositol trisphosphatase. It is also a non-phorbol ester-type tumor promoter on mouse skin. Useful for the study of protein phosphatases and of PP1/PP2A in cell extracts, as well as in intact cells. Induces apoptosis in human breast carcinoma (MB-231 and MCF-7) and in myeloid cells, but inhibits glucocorticoid-induced apoptosis in T-cell hybridomas. Has marked contractile effect on smooth muscles and heart muscles. Implicated as a causative agent of diarrhetic shellfish poisoning.

Neuronal activity induces topoisomerase IIβ (Top2B) to generate DNA double-strand breaks (DSBs) within the promoters of neuronal early response genes (ERGs) and facilitate their transcription, and yet, the mechanisms that control Top2B-mediated DSB formation are unknown. Here, we report that

The phosphorylation of mitotic proteins is bistable, which contributes to the decisiveness of the transitions into and out of M phase. The bistability in substrate phosphorylation has been attributed to bistability in the activation of the cyclin-dependent kinase Cdk1. However
