Supplementary information

RhoGDI also known as Rho GDP-dissociation inhibitor 1 is a regulatory protein with a mass of approximately 23 kDa. It primarily inhibits the dissociation of GDP from Rho GTPases such as RhoA Rac1 and Cdc42. This protein plays an important role in controlling the cycling between active GTP-bound and inactive GDP-bound states of small GTPases. RhoGDI shows expression in numerous tissues highlighting its widespread regulatory functions in cell signaling.

Biological function summary

RhoGDI modulates the activity of Rho family GTPases—a group responsible for organizing the actin cytoskeleton which determines cell shape polarity and movement. It does not operate alone; rather it is part of a complex with membrane-bound and cytosolic proteins offering a shuttle service to balance GTPases between cellular locations. By doing so RhoGDI influences processes like cell migration and the cell cycle integral to maintaining proper cellular architecture.

Pathways

Scientists recognize RhoGDI’s participation in key signaling pathways particularly the Rho GTPase cycle and actin cytoskeleton organization. It interacts with proteins like ROCK and PAK within these pathways to achieve precise control of cytoskeletal dynamics. RhoGDI coordinates with these proteins to play a central role in cellular responses to external stimuli impacting processes like wound healing and cellular development.

RhoGDI has associations with cancer and neurodegenerative diseases. Its deregulation can disrupt the Rho GTPase pathways leading to uncontrolled cell proliferation in cancers such as breast and prostate cancer. Additionally altered RhoGDI function affects neuronal growth and survival linking it to neurodegenerative conditions like Alzheimer’s disease. Within these contexts RhoGDI interacts with other proteins such as Rac1 and Cdc42 to influence disease progression and pathology.

Target data

Controls Rho proteins homeostasis. Regulates the GDP/GTP exchange reaction of the Rho proteins by inhibiting the dissociation of GDP from them, and the subsequent binding of GTP to them. Retains Rho proteins such as CDC42, RAC1 and RHOA in an inactive cytosolic pool, regulating their stability and protecting them from degradation. Actively involved in the recycling and distribution of activated Rho GTPases in the cell, mediates extraction from membranes of both inactive and activated molecules due its exceptionally high affinity for prenylated forms. Through the modulation of Rho proteins, may play a role in cell motility regulation. In glioma cells, inhibits cell migration and invasion by mediating the signals of SEMA5A and PLXNB3 that lead to inactivation of RAC1.
