Rho GDP-dissociation inhibitor binding

Definition

Target type: molecularfunction

Binding to a Rho GDP-dissociation inhibitor protein. [GOC:ai]

Rho GDP-dissociation inhibitor (RhoGDI) binding is a crucial regulatory mechanism in the control of Rho GTPase signaling. Rho GTPases are small monomeric G proteins that act as molecular switches, cycling between an inactive GDP-bound state and an active GTP-bound state. This cycling is tightly regulated by a complex interplay of guanine nucleotide exchange factors (GEFs), GTPase-activating proteins (GAPs), and RhoGDIs.

RhoGDIs are cytosolic proteins that bind to inactive Rho GTPases, effectively sequestering them in the cytoplasm and preventing their activation. This binding involves the insertion of the C-terminal prenyl group of the Rho GTPase into a hydrophobic pocket on the RhoGDI, a process that is crucial for the inhibitory function of RhoGDIs.

The binding of RhoGDI to Rho GTPases serves several important functions:

1. **Regulation of Rho GTPase activity:** RhoGDIs prevent the activation of Rho GTPases by preventing the exchange of GDP for GTP. This is important for maintaining the correct spatial and temporal distribution of active Rho GTPases within the cell.
2. **Control of Rho GTPase localization:** RhoGDIs sequester Rho GTPases in the cytoplasm, preventing their translocation to the plasma membrane where they can interact with downstream effectors.
3. **Protection from degradation:** RhoGDIs protect Rho GTPases from degradation by proteases.

The binding of RhoGDI to Rho GTPases is a dynamic process, with the association and dissociation of the two proteins regulated by various cellular signals. For example, the binding of RhoGDI to Rho GTPases can be disrupted by the activation of GEFs, which promote the exchange of GDP for GTP, leading to the activation of Rho GTPases.

In summary, RhoGDI binding is a fundamental mechanism for regulating the activity and localization of Rho GTPases. This interaction plays a critical role in a wide range of cellular processes, including cytoskeletal organization, cell adhesion, cell migration, and signal transduction.'

A non-steroidal anti-inflammatory drug, ketorolac is mainly used (generally as the tromethamine salt) for its potent analgesic properties in the short-term management of post-operative pain, and in eye drops to relieve the ocular itching associated with seasonal allergic conjunctivitis. It was withdrawn from the market in many countries in 1993 following association with haemorrhage and renal failure.
