RAC2 is a small signaling G protein/GTPase which is part of the RAS superfamily of small GTP-binding proteins which regulate cell growth， actin cytoskeletal organization， cell proliferation， survival， cell cycle progression， gene transcription rgulation and the activation of protein kinases. RAC2 cycles between an active gtp-bound and inactive gdp-bound state. In active state， RAC2 binds to a variety of effector proteins to regulate cellular responses， such as secretory processes， phagocytose of apoptotic cells and epithelial cell polarization. RAC2 is involved in the regulation of the nadph oxidase.
RAC2 although stable 4℃ for 4 weeks， should be stored desiccated below -18℃. For long term storage it is recommended to add a carrier protein （0.1% HSA or BSA）.
Please prevent freeze-thaw cycles.
