### CKMT1A Gene Overview

**Gene Symbol:** CKMT1A  
**Location:** Chromosome 15  
**Function:** The CKMT1A gene encodes the mitochondrial creatine kinase (MtCK), which is integral in energy metabolism by facilitating the transfer of high-energy phosphate from adenosine triphosphate (ATP) to creatine, forming phosphocreatine—a major energy reservoir. It exists in two isoforms: sarcomeric MtCK (from a different gene) and ubiquitous MtCK, with the latter having prominent expression in various tissues.

### 1. Associated Genes
While CKMT1A itself is a key player in energy metabolism, it may have associations with other genes involved in energy homeostasis and metabolic pathways. Notable associated genes include:
- **CKMT2**: The gene encoding the sarcomeric isoform of mitochondrial creatine kinase.
- **ATP synthase genes**, as they are functionally related due to their roles in ATP production.
- **Mitochondrial metabolism-related genes**, such as those involved in the electron transport chain (e.g., cytochrome c oxidase subunits).
  
### 2. Aging and Age-related Diseases
Research suggests that alterations in CKMT1A activity may be associated with age-related decline in muscle function and other degenerative conditions. Some known implications include:
- **Sarcopenia**: Decreased muscle mass and strength commonly observed in aging may be linked to impaired energy supply mediated by CKMT1A.
- **Neurodegenerative Diseases**: The role of mitochondrial function is crucial in neurodegenerative conditions like Alzheimer’s and Parkinson’s diseases, where disturbances in energy homeostasis may contribute to pathology.
- **Mitochondrial Dysfunction**: Changes in CKMT1A expression may correlate with age-related mitochondrial dysfunction often observed in aging tissues.

### 3. Drug Interactions
While direct drug interactions specifically targeting CKMT1A are not extensively documented, increased expression of CKMT1A in malignant tumors suggests potential roles in cancer therapies. Some classes of drugs that may indirectly interact or modulate related pathways include:
- **Cancer therapies**: Drugs targeting metabolic pathways, like those inhibiting glycolysis or affecting oxidative phosphorylation, could influence CKMT1A function.
- **Mitochondrial protectants**: Compounds like coenzyme Q10 and Resveratrol that aim to boost mitochondrial function may also influence CKMT expression/function.

### 4. Pathways and Biological Processes
CKMT1A is involved in several key biological pathways:
- **Energy Metabolism**: Primarily involved in the conversion of ADP to ATP via the creatine kinase reaction, crucial for cellular energy homeostasis.
- **Mitochondrial Biogenesis**: May play a role in maintaining mitochondrial function and biogenesis in high-energy demand tissues.
- **Regulation of Apoptosis**: High levels of CKMT1A expression in cancers suggest it may influence apoptotic pathways, potentially allowing for cancer cell survival despite energy demands.
- **Skeletal Muscle and Heart Function**: Important for the energy supply during muscle contraction and supporting cardiac rhythm and contractility.

This gene is a vital component of the energetic landscape within cells, particularly those with high energy demands, and it plays roles that span beyond normal physiology into pathology, particularly concerning cancer and aging.
