### PSKH1 Gene Overview

The PSKH1 gene (Pseudokinase with Serine Kinase Activity 1) encodes a serine kinase that is implicated in critical cellular processes, including pre-mRNA processing and protein phosphorylation. Evidence suggests that it plays a significant role in the trafficking of splicing factors and in the determination of left/right symmetry, particularly during heart development.

### 1. Associated Genes
There are several known genes associated with PSKH1, primarily related to its function in splicing and kinase activity. Some notable genes include:
- **SR proteins (SRSF proteins)**: These are a family of serine/arginine-rich splicing factors involved in pre-mRNA processing.
- **SRSF2**: A specific SR protein that is important for splice site selection and is associated with various cancers.
- **HNRNPH1**: A gene coding for heterogeneous nuclear ribonucleoprotein that interacts with RNA-binding proteins during splicing.

### 2. Association with Aging or Age-related Diseases
Though specific studies directly linking PSKH1 to aging or age-related diseases may be limited, several indirect connections can be made:
- **Splicing and Aging**: Given its role in pre-mRNA processing, PSKH1 may influence aging-related changes in gene expression and alternative splicing, which are known to impact cellular senescence and tissue function over time.
- **Cardiovascular Health**: Since PSKH1 is involved in heart development, dysfunctions in its activity may contribute to age-related cardiovascular diseases, including heart failure.

### 3. Drug Interactions
Currently, there are no well-established drugs or drug classes specifically known to target PSKH1. However, given its kinase activity, it may theoretically respond to general kinase inhibitors. Some classes that could potentially interact based on similar kinase functionalities include:
- **Protein Kinase Inhibitors**: These are compounds that could inhibit serine/threonine kinases in similar pathways, although specific interactions remain to be clarified through experimental validation.

### 4. Pathways and Biological Processes
PSKH1 is involved in various critical pathways and biological processes, including:
- **Spliceosome Assembly**: Its role in the trafficking of SR proteins connects it to spliceosome function, a core component of mRNA maturation.
- **Regulation of Alternative Splicing**: Direct involvement in the modulation of alternative splicing events, influencing gene expression variability.
- **Signal Transduction Pathways**: The kinase activity may play a role in broader signaling networks, though specific pathways remain to be fully characterized.

Additionally, PSKH1 is predicted to contribute to:
- **Heart Development**: Involvement in embryonic heart formation processes.
- **Determination of Left/Right Symmetry**: Important during early embryonic development.

In conclusion, PSKH1 appears to play an integral part in both basic cellular function and the developmental processes with suggested ties to diseases and aging, warranting further research for its potential implications.
