  Domain Name: Rnd3_RhoE_Rho8
Rnd3/RhoE/Rho8 GTPases. Rnd3/RhoE/Rho8 subfamily. Rnd3/RhoE/Rho8 is a member of the novel Rho subfamily Rnd, together with Rnd1/Rho6 and Rnd2/Rho7. Rnd3/RhoE is known to bind the serine-threonine kinase ROCK I. Unphosphorylated Rnd3/RhoE associates primarily with membranes, but ROCK I-phosphorylated Rnd3/RhoE localizes in the cytosol. Phosphorylation of Rnd3/RhoE correlates with its activity in disrupting RhoA-induced stress fibers and inhibiting Ras-induced fibroblast transformation. In cells that lack stress fibers, such as macrophages and monocytes, Rnd3/RhoE induces a redistribution of actin, causing morphological changes in the cell. In addition, Rnd3/RhoE has been shown to inhibit cell cycle progression in G1 phase at a point upstream of the pRb family pocket protein checkpoint. Rnd3/RhoE has also been shown to inhibit Ras- and Raf-induced fibroblast transformation. In mammary epithelial tumor cells, Rnd3/RhoE regulates the assembly of the apical junction complex and tight junction formation. Rnd3/RhoE is underexpressed in prostate cancer cells both in vitro and in vivo; re-expression of Rnd3/RhoE suppresses cell cycle progression and increases apoptosis, suggesting it may play a role in tumor suppression. Most Rho proteins contain a lipid modification site at the C-terminus, with a typical sequence motif CaaX, where a = an aliphatic amino acid and X = any amino acid. Lipid binding is essential for membrane attachment, a key feature of most Rho proteins. Due to the presence of truncated sequences in this CD, the lipid modification site is not available for annotation.
No pairwise interactions are available for this conserved domain.

Tips:
 If you've navigated here from a protein, hovering over a position on the weblogo will display the corresponding protein position for that domain position.

 The histograms below the weblogo indicate mutations found on the domain. Red is for disease (OMIM) and blue is for SNPs.

 Functional Features are displayed as orange boxes under the histograms. You can choose which features are displayed in the box below.
