PP2A-Cβ Inhibitors

Common PP2A-Cβ Inhibitors include, but are not limited to Okadaic Acid CAS 78111-17-8, Calyculin A CAS 101932-71-2, Cantharidin CAS 56-25-7, Fostriecin CAS 87860-39-7 and Tautomycin from Streptomyces spiroverticillatus CAS 109946-35-2.

PP2A-Cβ inhibitors belong to a specific chemical class of compounds designed to target and inhibit the activity of the catalytic subunit Cβ of Protein Phosphatase 2A (PP2A-Cβ). PP2A is a major serine/threonine phosphatase that regulates various cellular processes by dephosphorylating target proteins. The catalytic subunit Cβ is a critical component of the PP2A holoenzyme, which is involved in the dephosphorylation of specific substrates and the modulation of signaling pathways.

PP2A-Cβ inhibitors work by specifically targeting the PP2A-Cβ subunit, interfering with its catalytic activity and ability to dephosphorylate target proteins. By doing so, these inhibitors may modulate the balance of phosphorylation and dephosphorylation events in cellular signaling cascades, impacting various cellular responses and processes. Research into PP2A-Cβ inhibitors is ongoing to unravel their precise mechanisms of action and explore their implications in understanding protein phosphorylation dynamics. The study of PP2A-Cβ inhibitors contributes to a deeper understanding of the intricate mechanisms governing protein regulation and cellular signaling.
