Arp2/3 Complex

Actin-related protein 2/3 complex

The Arp2/3 complex is originally identified in Acanthamoeba and consists of seven proteins (actin-related proteins; Arp2 and Arp3, and Arp2/3 complex subunits; ARPC1-5) that are conserved in all eukaryotes, with the exception of some algae, microsporidia and protists. The complex plays an essential role in a wide variety of cellular processes including lamellipodia-mediated cell migration, endocytosis and phagocytosis, by virtue of its ability to generate branched actin filament networks

.

Activation of Arp2/3 requires interaction with actin nucleation-promoting factors (NPFs). Regulation of Arp2/3 activity is achieved by endogenous inhibitory proteins through direct binding to Arp2/3 and competition with NPFs or by binding to Arp2/3-induced actin filaments and disassembly of branched actin networks. Arp2/3 inhibition has recently garnered more attention as it has been associated with attenuation of cancer progression, neurotoxic effects during drug abuse, and pathogen invasion of host cells

    Cytochalasin D
    Inhibitor 99.79%
    Cytochalasin D (Zygosporin A) is a potent actin polymerization inhibitor, could be derived from fungus. Cytochalasin D has cell-permeable activity. Cytochalasin D inhibits the G-actin–cofilin interaction by binding to G-actin. Cytochalasin D also inhibits the binding of cofilin to F-actin and decreases the rate of both actin polymerization and depolymerization in living cells. Cytochalasin D can reduce exosome release, in turn reducing the amount of survivin present in the tumour environment. Cytochalasin D induces phosphorylation and cytoplasmic retention of Yap.
