### Overview of KMT2E Gene

**Gene Symbol:** KMT2E  
**Aliases:** MLL5, MLL4, MLL3, etc.  
**Location:** Chromosome 17q21  

KMT2E (Lysine Methyltransferase 2E) is a member of the KMT2 (MLL) family of histone methyltransferases, which play a crucial role in regulating gene expression through the modification of chromatin. The protein it encodes has significant roles in hematopoiesis, cell cycle regulation, and transcriptional activation of specific genes.

### 1. Associated Genes

While KMT2E has various interactions with genes in the context of hematopoiesis and cell cycle regulation, no specific unrelated associated genes were provided in your summary. Generally, KMT2E's function involves association with genes involved in:

- **E2F1:** As a transcription factor that regulates the G1/S transition.
- **HCFC1:** This gene codes for a transcriptional regulator that enchants KMT2E's activity.
- **Histone modifying genes:** Such as those involved in the methylation and acetylation processes with which KMT2E plays a part.

### 2. Age-Related Details

While a direct connection to aging or specific age-related diseases for KMT2E may not be abundantly documented, several general aspects can be inferred:

- **Cell Cycle Regulation:** Given KMT2E's role in regulating the cell cycle, dysregulation may potentially contribute to age-related degenerative processes or cancers, particularly in the context of hematopoietic function.
- **Hematopoietic Stem Cell (HSC) Activity:** Alterations in HSC self-renewal and differentiation influenced by KMT2E can have implications for age-related decline in hematopoiesis, leading to conditions such as anemia or compromised immune function with aging.
- **Epigenetic Regulation:** As aging is often associated with epigenetic changes, the methyltransferase function of KMT2E might be linked to shifts in gene expression profiles typical of aging.

### 3. Drug Interactions

Currently, there are no specific drugs or drug classes that have been heavily documented to directly target KMT2E. However, potential areas of interest in exploring drug interactions could include:

- **Inhibitors of histone methyltransferases:** Compounds like PRMT inhibitors or other epigenetic modulators may have downstream effects on pathways regulated by KMT2E.
- **Cancer therapeutics:** Given KMT2E's role in cell cycle regulation, drugs targeting mitotic processes or transcriptional regulation in hematological malignancies could interact indirectly.
- **Experimental compounds:** Novel compounds aimed at modifying the activity of chromatin-modifying enzymes could be potential areas for drug development related to KMT2E.

### 4. Pathways and Biological Processes

KMT2E is implicated in numerous biological processes, including:

- **Transcription regulation:** Directly related to enhancing transcriptional activation at E2F1-responsive promoters through tri-methylation of histone H3 at 'Lys-4' (H3K4me3).
- **Cell Cycle Progression:** Especially involved in the transition from G1 to S phase and is critical for proper S phase progression.
- **Hematopoiesis:** Key regulator of terminal myeloid differentiation and HSC self-renewal.
- **Differentiation processes:** Involved in the maintenance of quiescence in myoblasts and suppression of unwanted proliferation.
- **Epigenetic regulation:** Involves histone methylation that modifies chromatin state and thereby impacts gene expression.

### Conclusion

KMT2E is a pivotal component of various regulatory networks essential for normal cellular function, hematopoiesis, and the maintenance of cellular identity. Its regulatory roles extend to cell cycle control and epigenetic modifications, highlighting its potential impact on both normal physiology and disease states. Further research into KMT2E's functions could unveil additional therapeutic strategies, particularly in age-related diseases and malignancies.
