Research progress on the molecular structure, function, and application in tumor therapy of zinc transporter ZIP4

Area of Science:

• Molecular Biology
• Biochemistry
• Oncology

Background:

• ZIP4 protein is essential for cellular zinc homeostasis and is the causative gene for acrodermatitis enteropathica.
• The precise stereo-structural conformation and zinc ion transport mechanism of ZIP4 remain incompletely understood, with conflicting hypotheses.
• Emerging evidence implicates ZIP4 in tumor progression, metastasis, and drug resistance.

Purpose of the Study:

• To comprehensively review the molecular structure and zinc transport mechanisms of ZIP4.
• To explore the intricate relationship between ZIP4 and zinc ion regulation.
• To summarize recent findings on ZIP4's role in cancer and its therapeutic potential.

Main Methods:

• Literature review and analysis of existing research on ZIP4.
• Synthesis of data regarding ZIP4's structure, function, and involvement in biological processes.
• Critical evaluation of experimental findings and proposed hypotheses.

Main Results:

• ZIP4's dual role in zinc transport and direct interaction with Ephrin-B1 in tumor metastasis is highlighted.
• Evidence suggests ZIP4 regulates tumor behavior via zinc ions as second messengers and through direct protein interactions.
• ZIP4's involvement in tumor growth, metastasis, and drug tolerance is increasingly recognized.

Conclusions:

• Understanding ZIP4's structure and function is critical for deciphering its role in both health and disease.
• ZIP4 presents a promising therapeutic target for various cancers.
• Further research into ZIP4's molecular mechanisms can guide the development of novel anticancer strategies.
