Rho GTPases are inactive proteins modified by lipids for cellular targeting. This review covers methods to study how these posttranslational lipid modifications impact Rho GTPase function.
Area of Science:
- Biochemistry
- Cell Biology
- Molecular Biology
Background:
- Rho GTPases are key regulators of cellular processes.
- They are synthesized as inactive cytosolic proteins.
- Posttranslational lipid modification is crucial for their function.
Purpose of the Study:
- To review methods for studying Rho GTPase posttranslational modifications.
- To highlight the role of lipid modifications in Rho GTPase targeting and function.
Main Methods:
- Biochemical assays
- Cellular assays
- Pharmacologic inhibitors
Main Results:
- Posttranslational lipid modifications (isoprenoid or fatty acid) target Rho GTPases to specific cellular compartments.
- These modifications are essential for Rho GTPase function.
Conclusions:
- Understanding Rho GTPase lipid modifications is vital for studying their biology.
- Biochemical and cellular assays, along with pharmacologic tools, are instrumental in this research area.

Rab Proteins
Rab proteins switch between a cytosolic, GDP-bound inactive state and a membrane-anchored, GTP-bound active state. By themselves, Rabs show slow rates of GDP/GTP exchange and GTP hydrolysis. Thus, Rab proteins are considered...
