### IQCG Gene Summary

**Gene Symbol**: IQCG (IQ domain G protein-coupled receptor)

#### 1. Associated Genes
While the summaries provided do not cite specific genes beyond the context of its pathway and functional interactions, IQCG interacts with several other proteins involved in ciliary and flagellar motility, generally within the nexin-dynein regulatory complex (N-DRC). This may include:
- **DYNEIN** family members (e.g., DNAH family)
- **NEXIN** complex proteins
- Other genes involved in sperm motility and ciliogenesis, but specific gene names are usually provided in functional studies or through interaction databases (e.g., STRING, BioGRID).

#### 2. Aging and Age-Related Diseases
As of current knowledge, IQCG is primarily related to sperm motility and male fertility but does not have direct, well-established links to aging or age-related diseases. However, defects in ciliary function have been implicated in several age-related conditions, including Fertility-related issues. Dysregulation of calcium signaling pathways (where IQCG has a role through CAMK4) can also connect indirectly to age-related neurodegeneration and other age-related conditions, but more research is needed for definitive associations.

#### 3. Drug Interactions
The current state of knowledge does not specify drug interactions directly associated with the IQCG gene. However, drugs that influence calcium signaling (like calcium channel blockers) or those that may impact sperm motility may affect the cellular pathways where IQCG functions.

Endocrine disruptors may also have an indirect effect on genes regulating sperm motility, including IQCG, but specific drug classes haven't been conclusively tied to IQCG from current literature.

#### 4. Pathways and Biological Processes
The main pathways and biological processes related to IQCG include:
- **Ciliary/Flagellar Motility Regulation**: Involved in the nexin-dynein regulatory complex, maintaining ciliary/flagellar structure and function.
- **Sperm Axoneme Assembly**: Essential for the formation of the axoneme in sperm flagella necessary for motility.
- **Calcium Signaling Cascades**: Through calmodulin binding, IQCG contributes to pathways regulated by CAMK4, playing a role in calcium-dependent signaling processes.
  
Additionally, IQCG may be involved in cellular processes related to:
- **Ciliogenesis**: Formation and maintenance of cilia.
- **Cell Motility**: Overall roles in motility beyond sperm, potentially extrapolated to other ciliated cells in various tissues.
- **Spermatogenesis**: Direct involvement in male fertility processes.

Research is ongoing in the elucidation of all possible interactions and pathways for IQCG, and the discovery of any new associations remains an area of active investigation.
