  Domain Name: Rho3
Ras homology family 3 (Rho3) of small guanosine triphosphatases (GTPases). Rho3 is a member of the Rho family found only in fungi. Rho3 is believed to regulate cell polarity by interacting with the diaphanous/formin family protein For3 to control both the actin cytoskeleton and microtubules. Rho3 is also believed to have a direct role in exocytosis that is independent of its role in regulating actin polarity. The function in exocytosis may be two-pronged: first, in the transport of post-Golgi vesicles from the mother cell to the bud, mediated by myosin (Myo2); second, in the docking and fusion of vesicles to the plasma membrane, mediated by an exocyst (Exo70) protein. 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.
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.
