Okadaic acid, sodium salt is a potent inhibitor of serine/threonine-specific protein phosphatases 1 and 2A (PP1 and PP2A) and of 2B at higher concentrations.It does not inhibit protein tyrosine phosphatases or kinases which have been tested.
Application Notes
Okadaic acid has been used to study various cellular processes such as the cell cycle and apoptosis including microtubule organization and tau hosphorylation. This phosphatase inhibitor has also played a role in the study of nitric oxide metabolism and calcium signaling. In addition, okadaic acid has been shown to activate transcription of the Cox-2 gene, disrupt golgi, arrest transport in the rough endoplasmic reticulum, and affect neurotransmitter release.
