Rnd1 is a small (~21 kDa) signaling G protein (to be specific, a GTPase), and is a member of the Rnd subgroup of the Rho family of GTPases.[1] It is encoded by the gene RND1.[2]

It contributes to regulating the organization of the actin cytoskeleton in response to extracellular growth factors (Nobes et al., 1998).[supplied by OMIM][2]


Rnd1 has been shown to interact with GRB7,[3] PLXNB1,[4] PDE6D,[5][6] ARHGAP5[7] and UBXD5.[8]
