### RHOF Gene Overview

**Gene Symbol:** RHOF  
**Gene Type:** Protein Coding Gene  
**Location:** Extracellular exosome  
**Functions:** 
- GTP binding activity
- GTPase activity
- Protein kinase binding activity
- Actin filament organization

### Other Associated Genes

Although specific gene associations weren't mentioned in your provided summaries, the RHOF gene functions cooperatively with **CDC42** and **RAC** to promote actin-based structures, particularly filopodia formation. Other potential associated genes involved in cytoskeletal dynamics and signaling pathways that may have indirect interactions with RHOF include:

- **RHOA**: Another member of the Rho GTPase family involved in actin cytoskeleton organization.
- **RAC1**: A well-studied GTPase that also plays roles in cytoskeletal remodeling.
- **CDC42**: A GTPase important in regulating the cell cycle and actin dynamics.
- **PAK1**: P21-activated kinase, which is a downstream effector of CDC42 and RAC involved in cytoskeletal remodeling.
  
### Aging and Age-Related Diseases

The RHOF gene has not been widely reported in the context of aging or age-related diseases. However, the actin cytoskeleton plays a crucial role in cell morphology, motility, and maintenance of cellular integrity. Alterations in actin dynamics have been implicated in various age-related conditions such as:

- **Neurodegenerative Diseases**: Impaired actin rearrangements have been associated with disorders like Alzheimer's disease, contributing to synaptic dysfunction and neuroinflammation.
- **Cardiovascular Diseases**: Actin dynamics influenced by signaling pathways involving GTPases can affect vascular integrity and heart function, and age-related changes in these pathways could underlie cardiovascular aging.
- **Cancer**: Alterations in RHOF expression or function could contribute to tumor cell motility and metastatic potential, processes that become more critical with aging.

### Drug Interactions

As of October 2023, specific drugs that directly target RHOF are not well documented. However, compounds that influence the Rho family of GTPases or actin polymerization may indirectly affect RHOF function. Some classes of compounds that interact with pathways involving RHOF include:

- **Rho Kinase Inhibitors**: Drugs such as Fasudil, which inhibit Rho-kinase, may influence GTPase signaling pathways and indirectly affect RHOF's activity.
- **Actin Polymerization Inhibitors**: Drugs like Cytochalasins, which disrupt actin filaments, might impact processes where RHOF is involved.

### Pathways and Biological Processes

RHOF is involved in several biological pathways and processes, primarily related to cytoskeletal dynamics and cell signaling. Notable pathways include:

- **Rho GTPase Signaling Pathway**: Involves regulation of actin cytoskeleton and cell shape.
- **Cell Adhesion Pathways**: Impacts cell motility and morphology.
- **Neurodevelopment Pathways**: Plays a role in neurite outgrowth and synapse formation.
- **WNT Signaling Pathway**: Influences cellular processes such as proliferation, migration, and differentiation through actin remodeling.

In addition, RHOF's function in forming filopodia suggests its importance in cellular communication and signal transduction mechanisms in numerous cellular contexts.

Overall, RHOF is integral to actin dynamics, influencing various biological processes and demonstrating important interactions with other cellular pathways that may have implications in health and disease.
