Wrch1
RhoU is a small signaling G protein, and is a member of the Rho [family of GTPases].
Wrch1 was identified in 2001 as encoded by a non-canonical Wnt induced gene.
RhoU/Wrch delineates with RhoV/Chp a Rho subclass related to Rac and Cdc42, which emerged in early multicellular organisms during evolution.
