Background Information

What is the function of RhoA?

Ras homolog gene family, member A (RhoA) is a small GTPase that is involved in cytoskeleton organization.1 It is important in actomyosin contractility, as when RhoA binds to GTP it initiates a cascade of events mediating stress fiber or contractile ring formation, where actin bundles crosslink with other proteins. It is also associated with actin polymerization, making RhoA important in membrane ruffling and cell motility.2 The role of RhoA is essential in cell migration and adhesion.

 What is the cellular localization of RhoA?

In motile cells, a leading edge stretches ahead, stabilizes, the cytoskeleton is reorganized, and the tail of the cell retracts. The role of RhoA in contracting actomyosin has linked RhoA with the tail retraction in this process, but studies into the spatiotemporal kinetics of GTPases have revealed that RhoA is also located at the leading edge of migrating cells.3 This highlights the dual roles of this protein in actin contractility and polymerization.

 What is the role of RhoA in disease?

Though it is not an oncogene, the role of RhoA in adhesion and migration has implicated this protein in cancer biology. Expression of RhoA has been found to be higher in malignant tumors compared to benign tumors or in non-tumor tissue, and more invasive tumors have been found to overexpress RhoA.4 This protein is also implicated in neurodegenerative diseases and aging due to its role in axon guidance, with abnormal localization of RhoA associated with Alzheimer's and Parkinson's pathology.5,6
