Description

Okadaic acid is an inhibitor of PP-1 and PP-2A phosphatase proteins which occurs naturally as a neurotoxin. By inhibiting these proteins, okadaic acid causes an increase in myosin phosphorylation, inducing contraction of affected smooth muscle tissues. The acid was initially discovered in marine sponges of the genus Halichondria but can also be found in toxic shellfish. Our Okadaic acid is isolated from Prorocentrum concavum.

Applications

Owing to its ability to inhibit them, okadaic acid is used to identify phosphatases. In experiments examining the role of phosphorylation in pathological conditions, okadaic acid is used as a chemical probe for the process that can easily permeate cells. The acid has also been shown to promote both the growth of tumors and angiogenesis.

USE
Okadaic Acid, Potassium Salt is a potent inhibitor of serine/threonine-specific protein phosphatases PP1, PP2A, 5534, PP2C and endogenous phosphatase smooth muscle myosin. This inhibition action has been used to stimulate the activity of glucose transport and has been observed to block insulin's stimulation of glucose transport by inhibiting IRS-1 phosphorylation. Okadaic Acid, Potassium Salt has been used as a response modifier in the study of large granular lymphocyte and T-cell biochemistry. In addition to inhibitive activities it is a tumor promoter and has been used to study nitric oxide metabolism, apoptosis, cell cycle and calcium signaling.
