### JPT1 Gene Overview

**Gene Symbol:** JPT1  
**Location:** Nuclear membrane; nucleolus; nucleoplasm.

#### Protein Function Summary
JPT1 plays a significant role in cellular signaling and processes. It functions primarily to modulate AKT-mediated GSK3B signaling negatively. Through this mechanism, JPT1 is involved in the phosphorylation and degradation of CTNNB1 (also known as β-catenin). Specifically, JPT1 induces the phosphorylation of CTNNB1 at serine 33 while simultaneously suppressing the inhibitory phosphorylation at serine 9 of GSK3B. This action inhibits the components of the APC:CTNNB1:GSK3B complex and affects the cell adhesion properties by influencing the interaction with CDH1/E-cadherin at adherent junctions. Additionally, JPT1 is implicated in the regulation of the cell cycle and affects the AR (Androgen Receptor) signaling pathway, leading to receptor degradation via the proteasomal pathway.

### Associated Genes
While the summaries focus primarily on specific signaling pathways, other genes associated with JPT1's functions may include:
- **GSK3B (Glycogen Synthase Kinase 3 Beta)**: Influenced by JPT1 through phosphorylation dynamics.
- **CTNNB1 (Catenin Beta 1)**: The direct target of JPT1 activity concerning degradation.
- **CDH1 (Cadherin 1)**: A gene associated with cellular adhesion that interacts with the JPT1 pathway.
- **AR (Androgen Receptor)**: JPT1 has an antagonistic effect on this receptor signaling.

### Aging and Age-Related Disease Associations
While specific direct associations of JPT1 with aging or age-related diseases may not be extensively characterized, its role in cell signaling pathways suggests potential implications:
- **Cell Cycle Regulation**: Dysregulation of the cell cycle is a hallmark of aging and its associated diseases, including cancer.
- **Wnt/β-Catenin Signaling Pathway**: Alterations in this pathway, particularly through the action of β-catenin, have been implicated in age-related degenerative conditions and cancers.
- **Androgen Signaling**: Since JPT1 impacts the AR signaling pathway, it may have relevance in age-related conditions that involve hormonal signaling, such as prostate cancer or metabolic syndrome.

### Drug Interactions
Currently, there are no specific drugs or drug classes explicitly documented in the context of JPT1 interaction. However, given its role in signaling pathways, drugs affecting AR signaling, GSK3B activity (like lithium), or agents that modulate cellular adhesion may indirectly influence JPT1 outcomes.

### Pathways and Biological Processes
JPT1 has been linked to several significant biological processes and pathways, including:
- **Regulation of the Cell Cycle**: Impacts cell proliferation and division processes.
- **Canonical Wnt Signaling Pathway**: Involved through its interactions with β-catenin and GSK3B, impacting cell signaling related to development and cancer.
- **Cell Adhesion**: Interaction with cadherins indicates a vital role in maintaining tissue architecture and cell communication.
- **Regulation of Protein Degradation**: Particularly through the ubiquitin-proteasome pathway affecting receptor degradation, including AR.

### Conclusion
JPT1 is an important gene involved in various cellular functions, including cell adhesion, cell cycle regulation, and signaling pathways critical for maintaining cellular homeostasis. Its potential implications in aging and diseases warrant further investigation for a more comprehensive understanding of its biological significance and therapeutic potential.
