Structural highlights

Disease

RAC2_HUMAN Defects in RAC2 are the cause of neutrophil immunodeficiency syndrome (NEUID) [MIM:608203.^[1]

Function

RAC2_HUMAN Plasma membrane-associated small GTPase which cycles between an active GTP-bound and inactive GDP-bound state. In active state binds to a variety of effector proteins to regulate cellular responses, such as secretory processes, phagocytose of apoptotic cells and epithelial cell polarization. Augments the production of reactive oxygen species (ROS) by NADPH oxidase.^[2]
