Summary
Rho GTPase activating proteins (GAPs) regulate Rho protein activity, crucial for cell signaling. Dysregulation of RhoGAPs is linked to cancer, suggesting their potential as therapeutic targets.
Area of Science:
- Molecular Biology
- Cellular Signaling
- Oncology
Background:
- Rho proteins are small GTPases regulating cellular processes.
- Guanine nucleotide exchange factors (GEFs), GTPase activating proteins (GAPs), and guanine dissociation inhibitors (GDIs) control Rho protein activity.
- Over 70 RhoGAP proteins exist in the human genome, characterized by a RhoGAP domain and modular structures.
Purpose of the Study:
- To review the structure and function of RhoGAPs.
- To highlight the role of RhoGAPs in human cancers.
- To explore the therapeutic potential of RhoGAPs in cancer treatment.
Main Methods:
- Literature review of RhoGAP function and cancer association.
- Analysis of RhoGAP domain structure and protein interactions.
- Examination of RhoGAP expression in cancer cell lines and patient data.
Main Results:
- RhoGAPs possess diverse modular structures enabling protein interactions.
- Altered RhoGAP abundance is observed in various human cancers.
- RhoGAP-mediated signaling pathways are implicated in cancer development.
Conclusions:
- RhoGAPs are critical regulators of Rho signaling with implications in cancer.
- The modular nature of RhoGAPs contributes to their diverse functions.
- Targeting RhoGAPs offers a promising strategy for small molecule cancer therapeutics.

01:24Small GTPases - Ras and Rho
Ras and Rho are small monomeric GTPases that act downstream of receptor tyrosine kinase (RTK) and regulate various cellular processes. These GTPases switch between active and inactive states by binding to guanine nucleotides.

02:38The Ras Gene
The Ras-gene-encoded proteins are regulators of signaling pathways controlling cell proliferation, differentiation, or cell survival. The Ras-gene family in humans constitutes three primary members—the HRas, NRas, and KRas. These genes code for four functionally distinct yet closely related proteins—the HRas, NRas, KRas4A, and KRas4B. The involvement of mutant Ras genes in human cancer was first discovered in 1982 and is among the most common causes of human tumorigenesis.

02:14GTPases and their Regulation
Guanine nucleotide-binding proteins (G-proteins), also known as GTPases, are a superfamily of proteins that regulate many cellular processes, such as cell signaling, vesicular transport, and the regulation of cell shape and motility. Mutation or dysfunction of these proteins can lead to disease. There are around 40,000 known G-proteins that can broadly be classified into two groups ‒ small G-proteins consisting of a single domain and large multi-domain G-proteins.

01:22Activation and Inactivation of G Proteins
Heterotrimeric G proteins are guanine nucleotide-binding proteins. As the name suggests, heterotrimeric G proteins are composed of three subunits: alpha, beta, and gamma. They remain GDP-bound or GTP-bound inside the cells and switch between inactive/active states. The Gα subunit possesses the nucleotide-binding pocket that binds guanine nucleotides and switches between GDP or GTP-bound states. In contrast, the Gꞵ and Gγ subunits are always bound together with high affinity and are together...
01:33Cancer-Critical Genes I: Proto-oncogenes
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
