Rnd2 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 RND2.[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]

This particular family member has been implicated in the regulation of neuronal morphology and endosomal trafficking.

The gene localizes to chromosome 17 and is the centromeric neighbor of the breast-ovarian cancer susceptibility gene BRCA1.[2]


Rnd2 has been shown to interact with RACGAP1,[3] ARHGAP5[4] and UBXD5.[5]
