RhoV (or Chp or Wrch2) is a small (~21 kDa) signaling

G protein G proteins, also known as guanine nucleotide-binding proteins, are a family of proteins that act as molecular switches inside cells, and are involved in transmitting signals from a variety of stimuli outside a cell to its interior. Their a ...

Rho family of GTPases The Rho family of GTPases is a family of small (~21 kDa) signaling G proteins, and is a subfamily of the Ras superfamily. The members of the Rho GTPase family have been shown to regulate many aspects of intracellular actin dynamics, and are foun ...

. Chp was identified in 1998 as a GTPase interacting with the p21 activated kinase PAK2. RhoV/Chp delineates with RhoU/Wrch a Rho subclass related to Rac and Cdc42, which emerged in early multicellular organisms during evolution. RhoV/Chp depends on palmitoylation rather than prenylation for association with plasma and intracellular membranes. In Xenopus embryos, RhoV is encoded by a canonical Wnt response gene and is induced in the developing neural crest at specification. RhoV activity cooperates with the Snai1 (Snail) transcription factor for the subsequent induction of the pro-invasive transcription factors Snai2 (Slug),

Sox9 Transcription factor SOX-9 is a protein that in humans is encoded by the ''SOX9'' gene. Function SOX-9 recognizes the sequence CCTTGAG along with other members of the HMG-box class DNA-binding proteins. It is expressed by proliferating but n ...
