Geldanamycin is a benzoquinone ansamycin antibiotic which binds to Hsp90 (Heat Shock Protein 90) and alters it function. Hsp90 is a highly conserved and very abundant protein in the cytosol of both eukaryotic and prokaryotic cells. Hsp90 plays a key role in regulating the physiology of cells exposed to environmental stress and in maintaining the malignant phenotype of tumor cells. HSP90 client proteins play important roles in the regulation of the cell cycle, cell growth, cell survival, apoptosis, and oncogenesis. Geldanamycin binds with a high affinity into the ATP binding pocket in Hsp90 and induces the degradation of proteins that require this chaperone for conformational maturation.
