Inhibition of HSP90 activity by drugs like geldanamycin (GA) destabilizes client proteins which ultimately lead to the onset of apoptosis.

Back cover, clockwise from top left: Maltose binding protein (translucent), shown suspended in its molten globule state with chaperone protein SecB (yellow), destined for transport across the cellular membrane. Philipp Bechtluft, Arnold Driessen, Sander Tans and Graham Johnson. Nuclear localization of Hsp10 in cultured human lung fibroblasts. The image shows Hsp10 in the cytoplasm and in the nucleus of most cells in a culture of the human lung fibroblast cell line, HLF-1. The chaperonin is considered a mitochondrial protein but here we demonstrate by immunohistochemistry that it also occurs in the cytoplasm and in the nucleus. Bar = 50 microns. Simona Corrao. University of Palermo. Structure of the oligomeric small heat shock protein, alphaB-Crystallin, determined by solid-state NMR. The structure reveals that the C-terminus IXI motif from one unit in the oligomer binds in the substrate-binding groove of a neighboring until, suggesting an auto-inhibitory mechanism for chaperone activity. Rachel Klevit, University of Washington. Artwork prepared by S. Jehle. Structure of the protein alpha-crystallin determined by electron microscopy. Johannes Buchner, Technische Universität München. Several ribosomes (brown) are shown translating a messenger RNA (gray). As the elongating nascent protein (orange) emerges from the ribosome, it undergoes limited folding, but interactions with the exit tunnel and the surrounding area (shaded red) prevent the acquisition of stable tertiary structure. The ribosome effectively acts as a chaperone to prevent premature folding and misfolding of the nascent chain. After release from the ribosome, the free protein folds into its native structure (large orange structure). These conclusions are based on our single molecule force spectroscopy data probing the folding state of ribosome- associated nascent chains. Christian Kaiser, University California, Berkeley.
