Standaert et al (1999) Okadaic acid activates atypical protein kinase C (ζ/λ) in rat and 3T3/L1 adipocytes. J.Biol.Chem. 274 14074 PMID: 10318822 . Merck Index 12 6958 If you know of a relevant reference for Okadaic acid, please let us know.
If you're struggling to get stomach acid reli This is the definition of a strong acid as the term is used in chemistry. Examples of strong acids are listed. A strong acid is one that is completely dissociated or ionized in an aqueous solution. It is a chemical species with a high capac Teichoic acid is a structure found exclusively in gram-positive bacterial cell walls. This acid is formed through the joining of either glycerol phosphate Teichoic acid is a structure found exclusively in gram-positive bacterial cell walls.
Okadaic-acid, a 38-carbon fatty acid isolated from the black sponge Halichondria okadai, can stimulate lipolysis by promoting the phosphorylation of several proteins in adipocytes. Okadaic Acid: Equivalent Term Ocadaic Acid: CAS Registry Number 78111-17-8 Definition : A specific inhibitor of phosphoserine/threonine protein phosphatase 1 and 2a. It is also a potent tumor promoter. It is produced by DINOFLAGELLATES and causes diarrhetic SHELLFISH POISONING. Structure : Top Interacting Genes Scientific Opinion: Marine biotoxins in shellfish - okadaic acid and analogues; EFSA’s CONTAM Panel[1] has assessed the available data and identified for OA-group toxins a level at which most consumers, even those eating a large portion of shellfish, would be unlikely to get shellfish poisoning.
Okadaic acid is a marine sponge toxin which potently inhibits certain serine/threonine protein phosphatases. This cell permeable inhibitor targets the multiple isoforms of PP1 (IC 50 = 10-50 nM), both isoforms of PP2A (IC 50 = 0.5 nM) and PP3 (IC 50 = 4 nM). 1,2,3 It is a very weak inhibitor of PP2B (IC 50 > 2 μM) and does not inhibit PP2C or other phosphatases. 1,3 Presumably through these
At frog junctions, the addition of 1 microM okadaic acid to the extracellular fluid caused almost a doubling of the amplitude of the end-plate potential. The effect of 19 Dec 2016 And stronger acids become negatively charged more easily than weak acids.
av CG Gahmberg — Treatment with okadaic acid reveals strong threonine phosphorylation of CD18 after activation of. CD11/CD18 leukocyte integrin with phorbol esters or CD3.
En specifik hämmare av fosfoserin/treonin proteinfosfatas 1 och 2a. Det är också en potent tumörpromotor.
It has also been isolated from another marine sponge, H. malanodocia, as a cytotoxin. Okadaic Acid. Okadaic acid (or okadeic acid, CAS 78111-17-8, C44 H 68 O 13) is produced by dinoflagelates Dinophysis sp. and Prorocentrum lima. Lipophilic okadaic acid is a potent inhibitor of protein phosphorylase phosphatase-1 and -2A in the cytosol of the mammalian cells that dephosphorylates serine and threonine. Okadaic acid, 97% | C44H68O13 | CID 131839562 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological
Okadaic acid is an inhibitor of the serine/theorine protein phosphatases PP1 (IC 50 = 15-20 nM) and PP2A (IC 50 = 0.1 nM), exhibiting much greater activity towards the latter. PP2A is completely inhibited at 1-2 nM, compared to greater than 1 µM for PP1 (1).

Taken together, these results reveal the presence of an okadaic acid-sensitive pathway in neurite outgrowth and imply that protein phosphatase plays a positive role in regulating the neuritogenic effects of NGE.
Okadaic acid significantly increased phosphorylation of CaMKII; indicating a major role of PP1 in CaMKII dephosphorylation.

Okadaic acid-treatment applied to cultures containing predominantly differentiated chondrocytes (after day 4) did not influence the cartilage formation. 3H-thymidine and bromodeoxyuridine incorporation-assays demonstrated enhanced cell proliferation in the okadaic acid-treated colonies compared to that of the untreated ones.
