Application

CK-666 may be used to study Arp2/3-mediated structural changes in cells.

Biochem/physiol Actions

CK-666 binds to Arp2/3 complex, stabilizes the inactive state of the complex and prevents its movement into active conformation.
CK-666 is a cell-permeable inhibitor of actin assembly mediated by actin-related protein Arp2/3 complex.

Actin-related protein 2/3 (Arp2/3) complex is a seven-subunit assembly that nucleates branched actin filaments. Small molecule inhibitors CK-666 and CK-869 bind to Arp2/3 complex and inhibit nucleation, but their modes of action are unknown. Here, we use biochemical and structural

Palladin is an important component of motile actin-rich structures and nucleates branched actin filament arrays in vitro Here we examine the role of palladin during Listeria monocytogenes infections in order to tease out novel functions of palladin. We show that

Legionella pneumophila (Lp) exhibits different morphologies with varying degrees of virulence. Despite their detection in environmental sources of outbreaks and in respiratory tract secretions and lung autopsies from patients, the filamentous morphotype of Lp remains poorly studied.
