C3 transferase protein C3转移酶蛋白
Product Uses Include
Inhibition of RhoA, B and C in vitro
Inhibition of RhoA, B and C in vivo (See Table 1 for examples of use)
Material
Exoenzyme C3 transferase is an ADP ribosyl transferase that selectively ribosylates RhoA, RhoB and RhoC proteins on asparagine residue 41, rendering them inactive. It has extremely low affinity for other members of the Rho family such as Cdc42 and Rac1 and does therefore not affect these GTPases. Hence, C3 transferase is a very potent and useful reagent to specifically block RhoA/B/C signaling.
C3 transferase has been produc ed by expression in E. coli as a His-tagged protein. The recombinant protein is 24 kDa in size and is supplied as a lyophilized powder. Reconstitution of the protein in water to 1 mg/ml leaves the protein in the following buffer: 20 mM Tris pH 7.5, 50 mM NaCl, 0.5% sucrose and 0.1% dextran. Protein concentration is determined by the Precision Red Advanced Protein Assay Reagent Cat. # ADV02.
C3 transferase protein is also available in a cell permeable format (Cat. CT04) for fast, efficient and simple inhibition of RhoA/B/C in living cells.
Purity
Purity is determined by scanning densitometry of protein run on SDS-PAGE gels. CT03 consists of more than 90% pure exoenzyme C3 Transferase.
