### MYH15 Gene Overview

**Gene Symbol**: MYH15  
**Location**: Located on chromosome 3 in humans.  
**Function**: The MYH15 gene encodes a member of the myosin superfamily of proteins, specifically a non-sarcomeric myosin. It is predicted to enable several functions, including:
- ATP binding activity
- Actin filament binding activity
- Calmodulin binding activity

**Biological Role**: MYH15 is involved in muscle contraction and is particularly linked to extraocular skeletal muscle development. Myosins are motor proteins that play a critical role in cellular movement and division.

### 1. Associated Genes
MYH15 has potential interactions or functional associations with genes involved in muscle development and function, but specific gene partners can vary based on studies and biological contexts. As of my last dataset, specific genes that have been associated through interaction studies or co-expression may include:

- *MYH1*: Another myosin heavy chain involved in skeletal muscle.
- *MYH2*: A myosin associated with fast-twitch muscle fibers.

Additional RNA-seq data or genomic studies may further elucidate such associations.

### 2. Aging and Age-Related Diseases
While specific research explicitly linking MYH15 to aging processes or diseases is limited, myosins and the muscular system at large are implicated in several age-related conditions, such as:
- Sarcopenia: Age-related muscle loss, potentially affecting the expression and function of myosins, including MYH15.
- Eye disorders: Given the role of MYH15 in extraocular muscle development, dysfunctions related to eye movement (like strabismus) may also be relevant in aging populations.

Current literature should be consulted for the latest insights into these associations.

### 3. Drug Interactions
Information about direct drug interactions with the MYH15 gene or its protein product is not abundantly documented. However, the general classes of drugs that could potentially affect myosin function or muscle contractility include:
- Calcium channel blockers (targeting muscle contraction mechanisms)
- Antagonists of the Rho-associated protein kinase (ROCK) pathway, which influences smooth muscle contraction.

It's important to note that while these classes may not interact directly with MYH15, they could influence the pathways in which MYH15 is involved.

### 4. Pathways and Biological Processes
MYH15 is involved in numerous biological processes:
- Muscle contraction and relaxation
- Cytoskeleton organization and dynamics
- Cellular motility
- Developmental pathways related to muscle formation, particularly involving the extraocular muscles.

Some pathways that include MYH15 in their broader context may involve:
- The actin cytoskeleton signaling pathway
- Muscle differentiation and development pathways
- Neuromuscular junction formation and functioning

Further engagement with specific databases or literature is recommended for the most detailed current research on MYH15's roles in biological pathways. 

### Conclusion
The MYH15 gene plays a significant role in muscle function, particularly in extraocular muscles, influencing development and contraction. While there may not be extensive connections documented in aging-related pathways or drug-interaction specifics, ongoing research continuously sheds light on myosin family genes and their implications in health and diseases.
