The Rac1 activation kit provides a simple, convenient and efficient tool for monitoring the activation of the small GTPase, Rac1. This assay uses a GST-fusion protein containing the p21-binding domain (PBD) of human p21-activated kinase 1 (Pak1) to affinity precipitate active Rac1 (GTP-Rac1) from cell lysates. The GST-Pak-PBD fusion protein (~35kDa) is incubated with cell lysate and a glutathione resin. The pulled-down active or GTP-Rac1 is detected by Western blot analysis using a specific Rac1 Antibody.

Scientific Background: | Rac, cdc42 and the Rho subfamilies belong to the Rho-family of small GTP-binding proteins (G proteins or GTPases), which have been implicated in regulating a variety of cellular functions including actin cytoskeleton organization, cell growth control and development, transcriptional activation, membrane trafficking, and cell transformation. Cdc42/Rac are important upstream regulators of the protein kinase cascade that controls the SAPK/Jnk and p38 activity. Like all small GTPases, Rac acts as a switch regulating molecular events by cycling between an inactive GDP-bound state and an active GTP-bound state. |
