Isoform Comparison

Biological Activity

Description
CK-666 is a potent inhibitor of the Arp2/3 complex, an actin-related protein, displaying an IC50 value of 12 μM. By binding to the Arp2/3 complex, CK-666 stabilizes its inactive form and prevents the movement of Arp2 and Arp3 subunits into an activated, filament-like conformation[1].[2].
