Understanding the structural characteristics of Hsp90 is crucial to appreciating its diverse functions in cellular biology. The architecture of this protein significantly influences its role as a chaperone, particularly in protein folding and stability. By delving into the molecular composition, functional domains, and conformational changes of Hsp90, we gain insights into how it executes its responsibilities in cellular processes and its therapeutic potential.
Molecular Composition
Hsp90 is a complex protein composed primarily of amino acids. Its structure consists of three main regions: the N-terminal domain, the middle domain, and the C-terminal domain. This tripartite organization is essential for its activity.
- N-terminal domain: This part is crucial for ATP binding. The ability of Hsp90 to hydrolyze ATP is integral to its chaperone function.
