Enables several functions, including GTP binding activity; GTPase activity; and calmodulin binding activity. Involved in several processes, including Ras protein signal transduction; regulation of Cdc42 protein signal transduction; and regulation of neuron projection development. Located in several cellular components, including cell body; dendritic tree; and nucleus. Is expressed in central nervous system; lung; and neural retina. Orthologous to human RIT2 (Ras like without CAAX 2). [provided by Alliance of Genome Resources, Apr 2022]
