RND2 (RHON) is an atypical RHO GTPase and the least studied member of the RND subfamily. RND2 is constitutively bound to GTP and lacks GTPase activity. No guanine nucleotide exchange factors (GEFs), GTPase activator proteins (GAPs) or guanine nucleotide dissociation inhibitors (GDIs) act on RND2. RND2 is predominantly expressed in brain, testis and liver (Nobes et al. 1998; Nishi et al. 1999). RND2 regulates neurite outgrowth and branching (Fujita et al. 2002; Kakimoto et al. 2004; Tanaka et al. 2006; Wakita et al. 2011) and migration of newborn neurons within the embryonic cerebral cortex (Nakamura et al. 2006; Heng et al. 2008; Alfano et al. 2011; Pacary et al. 2011; Gladwyn-Ng et al. 2015; Heng et al. 2015).
