General description

Product Source: GST fusion-protein, corresponding to the p21-binding domain (PBD, residues 67-150) of human PAK-1, expressed in E. coli.

Quality

Routinely evaluated by G-protein activity assay

Physical form

300 µg of PAK-1 PBD, GST in 150 µL of PBS, pH 7.4, 0.5 mM PMSF, containing 20% glycerol.

Storage and Stability

Stable for 1 year at -20C from date of shipment. For maximum recovery of product, centrifuge the vial prior to removing the cap.

Analysis Note

Specific Activity: Affinity Precipitation Assay: 10 µg of this lot when added with 10 µL glutathione agarose, precipitated Rac-GTP from 3T3 and A431 cell lysates that were loaded in vitro with GTPγS. GDP treated of 3T3 and A431 lysates served as negative controls. Precipitated Rac-GTP was detected by immunoblot analysis using 1 &micor;g/mL anti-Rac (Catalog # 05-389) and secondary goat anti-mouse HRP antibody (Catalog # 12-349) on a Western Blot.

It has been recently reported that insulin recruits a novel signaling machinery to lipid rafts required for insulin-stimulated GLUT4 translocation [Baumann, A., Ribon, V., Kanzaki, M., Thurmond, D. C., Mora, S., Shigematsu, S., Bickel, P. E., Pessin, J. E. &

Responses to the effects of ethanol are highly conserved across organisms, with reduced responses to the sedating effects of ethanol being predictive of increased risk for human alcohol dependence. Previously, we described that regulators of actin dynamics, such as the

A major function of Rac2 in neutrophils is the regulation of oxidant production important in bacterial killing. Rac and the related GTPase Cdc42 also regulate the dynamics of the actin cytoskeleton, necessary for leukocyte chemotaxis and phagocytosis of microorganisms. Although

We previously identified the R-enantiomer of ketorolac as an inhibitor of the Rho-family GTPases Rac1 and Cdc42. Rac1 and Cdc42 regulate cancer-relevant functions, including cytoskeleton remodeling necessary for tumor cell adhesion and migration. This study investigated whether administration of racemic
