The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
1/1000. Detects a band of approximately 32, 44 kDa (predicted molecular weight: 45 kDa).
FunctionFunctions 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 similaritiesBelongs to the actin family. ARP2 subfamily.
