      Background InformationRhoE, also known as Rnd3, (Rho family GTPase 3) is a small G-protein that is a member of the Rnd family of Rho GTPases, which is a part of the Ras superfamily. The activity of Rnd1, Rnd2, and Rnd3/RhoE are not activated by the traditional conformational change of the GTP binding like other Rho family members. As the name dictates, Rnd proteins were associated with making a cell “round”. Like other small G-proteins, the do bind GTP, but unlike other G-proteins, they do not hydrolyze GTP to GDP. The actions of RhoE are associated with the actin cytoskeletal organization in response to external stimuli. RhoE acts antagonistically to RhoA in inducing loss of stress fiber formation, in part by binding to the RhoA downstream kinase Rho-associated kinase (ROCK1). This prevents ROCK1 activation and inhibits downstream signaling. RhoE does go through the post-translation modification of farnylation which enables it to localize and bind to various internal membranes. RhoE is also known to effect cycle progression.

      Entrez Gene Number
      Entrez Gene SummaryMembers of the Rho family of Ras-related GTPases, such as ARHE, regulate the organization of the actin cytoskeleton in response to extracellular growth factors. Like Ras (MIM 190020), Rho family members appear to cycle between an inactive GDP-bound form and an active GTP-bound form. Three major regulators of Rho activity have been identified: RhoGDIs, which interact with the GDP-bound Rho proteins to keep them in a resting complex (see MIM 601925); GEFs, which promote GDP/GTP exchange leading to activation of Rho proteins (see MIM 601855); and GAPs, which stimulate GTP hydrolysis and return the activated Rho protein to its inactive form (see MIM 602680) (Nobes et al., 1998 [PubMed 9531558]).[supplied by OMIM
