  • Application notes
    Is unsuitable for ICC/IF,IHC-P or IP.
  • Target

    • Function

      Functions as ATP-binding component of the Arp2/3 complex which is involved in regulation of actin polymerization and together with an activating nucleation-promoting factor (NPF) mediates the formation of branched actin networks. Seems to contact the pointed end of the daughter actin filament.
    • Sequence similarities

      Belongs to the actin family. ARP2 subfamily.
    • Cellular localization

      Cytoplasm > cytoskeleton. Cell projection.
