Product Uses Include:
Precipitation of active Rac and Cdc42 from cell lysates
Inhibition of Rac and Cdc42 activity in vitro
Blocking of Rac and Cdc42 function in vivo by microinjection
Material
The Rac/Cdc42 (p21) binding domain (PBD) of the human p21 activated kinase 1 protein (PAK) protein has been expressed as a GST-fusion protein in E. coli. This protein binds binds specifically to GTP-bound, and not GDP-bound, Rac and Cdc42 proteins. The domain can therefore be used to specifically precipitate active, GTP-bound Rac and Cdc42 as well as to specifically block the activity of Rac and Cdc42 in vitro and in vivo.
The GST-PAK-PBD contains residues 67-150 of PAK. This region includes the highly conserved CRIB motif plus sequences required for the high affinity interaction with GTP-Rac and GTP-Cdc42.
The protein is supplied as 250 µg of lyophilized product and the protein is also available in a bead bound format (Cat. # PAK02). This product is also used in our Cdc42 and Rac activation assay Biochem Kits™ (Cat. # BK034 and BK035, repectively)Please contact us at for specific academic pricing.
