The HSP90 Family: Structure, Regulation, Function, and Implications in Health and Disease

Area of Science:

• Molecular Biology
• Cell Biology
• Biochemistry

Background:

• Heat shock protein 90 (HSP90) is a highly conserved protein family essential for cellular homeostasis.
• HSP90 and its co-chaperones regulate critical cellular processes including cell survival, cell cycle control, hormone signaling, and apoptosis.

Purpose of the Study:

• To review the structure, regulation, and function of the HSP90 protein family.
• To explore the role of HSP90 in various pathologies, including cancer and neurodegenerative diseases.
• To highlight HSP90 as a potential therapeutic target for disease treatment.

Main Methods:

• Literature review of HSP90 family proteins.
• Analysis of HSP90's role in cellular homeostasis and physiological processes.
• Investigation of HSP90's involvement in pathological conditions.

Main Results:

• HSP90 proteins are distributed across cellular compartments, underscoring their importance.
• HSP90 plays a crucial role in orchestrating key cellular functions.
• Aberrant HSP90 activity and secreted forms are implicated in cancer and neurodegenerative diseases.

Conclusions:

• HSP90 is a critical regulator of cellular processes and homeostasis.
• Targeting HSP90 presents a viable therapeutic avenue for treating cancer and neurodegenerative disorders.
• Further research into HSP90's structure, regulation, and function is warranted for therapeutic development.
