Human CTR1 Through the Ages: Milestones and Emerging Roles in Disease and Therapy

Area of Science:

• Biochemistry
• Molecular Biology
• Cell Biology

Background:

• Copper transporter 1 (CTR1) is the main high-affinity Cu(I) importer in eukaryotic cells.
• CTR1 is essential for maintaining copper homeostasis, critical for numerous biological functions.
• Research on human CTR1 (hCTR1) has evolved from basic characterization to detailed structural and functional insights.

Purpose of the Study:

• To summarize the current knowledge of human CTR1 (hCTR1).
• To explore hCTR1's structure, copper-binding sites, regulation, and trafficking.
• To highlight hCTR1's involvement in diseases and its potential as a therapeutic target.

Main Methods:

• Review of existing literature on hCTR1 structure, function, and disease association.
• Analysis of biochemical and structural data.
• Synthesis of findings on hCTR1's role in copper metabolism and disease.

Main Results:

• Detailed understanding of hCTR1's structural features and copper-binding motifs.
• Elucidation of hCTR1 regulation and cellular trafficking pathways.
• Emerging evidence links hCTR1 to cancer, neurodegenerative disorders, and inherited copper metabolism syndromes.

Conclusions:

• hCTR1 is a key player in copper homeostasis with significant implications for human health.
• hCTR1 presents potential as a therapeutic target and a facilitator for drug delivery.
• Further research is needed to fully realize the biomedical potential of hCTR1.
