RhoU (or Wrch1 or Chp2) is a small (~21 kDa) signaling G protein (more specifically a GTPase), 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.
Model organisms have been used in the study of RhoU function. A conditional knockout mouse line, called Rhoutm1a(KOMP)Wtsi was generated as part of the International Knockout Mouse Consortium program — a high-throughput mutagenesis project to generate and distribute animal models of disease to interested scientists — at the Wellcome Trust Sanger Institute.
Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion. Twenty three tests were carried out on mutant mice, but no significant abnormalities were observed.
Heavily Father, forgive us for we are sayin'
Yeahhh, I just got it
