Rac is a member of the Rho family of small GTP-binding proteins, and plays roles in cytoskeletal actin organization as well as transformation. Rac is activated downstream of cdc42, or independently by Ras signaling, and in turn Rac stimulates Rho. Activation of Rac results in the formation of lamellipodia, whereas cdc42 stimulates filopodia formation, and Rho stimulates formation of actin stress fibers. Effectors of the Rac pathway include NADPH Oxidase and the SAPK1/JNK family of kinases. The latter pathway is activated by the PAK kinases, which are direct targets of Rac.

Recognizes Rac1, does not cross react with Cdc42. Rac1 is a member of the Rho family of small GTPases. Small GTPases act as molecular switches in regulating a variety of biological response pathways by cycling from the GDP-bound (inactive) and GTP-bound (active) states. Rac regulates actin polymerization to form lamellipodia.

Synthetic peptide corresponding to amino acids 130-141 of human Rac1 (KEKKLTPITYPQ-C).
