DESCRIPTION

Also known as RAC2_HUMAN, RAC2. 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. Interacts with DOCK2, which may activate it. Interacts with S100A8 and calprotectin (S100A8/9) (PubMed:10559471, PubMed:15642721). Found in a complex with SH3RF1, MAP3K7/TAK1, MAP2K7/MKK7, MAPK8IP1/JIP1, MAPK8/JNK1 and MAPK9/JNK2 (By similarity). Interacts with PAK1 (PubMed:30723080, PubMed:30654050).
