The **NUP85** gene, located on chromosome 1, encodes a protein that is a crucial component of the **Nup107-160 subcomplex** of the **nuclear pore complex (NPC)**. This subcomplex is essential for the assembly, maintenance, and function of the NPC, which regulates the transport of macromolecules between the nucleus and the cytoplasm. The role of NUP85 extends to facilitating RNA export, and it is involved in the assembly of the mitotic spindle during cell division.

### 1. Associated Genes:
NUP85 interacts with and is associated with several other genes, which may include (but are not limited to):
- **NUP107**: A core component of the Nup107-160 subcomplex of the NPC.
- **NUP96**: Interacts with NUP85 and is relevant for the structure of the NPC.
- **NUP153**: Another nuclear pore component that associates with the Nup107-160 complex.
- **CCR2**: The chemokine receptor that NUP85 can bind to and influence monocyte mobility and inflammation.
- **CCL2 (MCP-1)**: Chemokine whose signaling is influenced by NUP85's interaction with CCR2.

### 2. Aging and Age-Related Diseases:
Current research indicates that **NUP85** may have potential implications in aging and age-related diseases, particularly those involving cellular transport and inflammatory responses. Disruption in nuclear pore complex components has been linked to:
- **Laminopathies**: A group of diseases arising from mutations in nuclear lamina proteins, where NUP proteins may also play a role in the nuclear architecture.
- **Neurodegenerative disorders**: Abnormalities in the function of nuclear pore complexes have been implicated in diseases like ALS and Huntington's Disease.
- **Age-related inflammation**: Since NUP85 is involved in monocyte chemotaxis via CCR2, it may influence inflammatory processes that are common in age-related diseases.

### 3. Drug Interactions:
There are no direct drugs specifically targeting NUP85 as of the last available updates, but since it is involved in pathways that modulate immune responses, there may be indirect links to drug classes used in inflammatory and autoimmune conditions, such as:
- **CCR2 antagonists**: These would influence the pathways involving CCR2 and could potentially intersect with NUP85-mediated processes.
- **Immunomodulators**: General drugs affecting inflammation may indirectly relate to NUP85’s role in chemotaxis of immune cells.

### 4. Pathways and Biological Processes:
NUP85 is involved in several key biological pathways and processes:
- **Nuclear pore complex assembly and maintenance**: Vital for the structural integrity of the NPC.
- **RNA export and processing**: Crucial for gene expression regulation.
- **Regulation of gene expression**: Through its interaction with chromatin-associated proteins.
- **Cell cycle progression**: Particularly during mitosis, aiding in spindle formation.
- **Chemotaxis and inflammatory response**: Participating in monocyte migration mediated by CCL2/CCR2 signaling pathways.
- **Nephrogenesis**: Implicated in kidney development, signaling that links NUP85 to development-related processes.

Further research into NUP85 might provide more insights into its broader role in health and disease, particularly as it relates to aging and immunological functions.
