| Additional info: | Hsp90 is an abundantly and ubiquitously expressed heat shock protein. It is understood to exist in two principal forms .alpha. and .beta., which share 85% sequence amino acid homology. The two isoforms of Hsp90, are expressed in the cytosolic compartment. Despite the similarities, Hsp90.alpha. exists predominantly as a homodimer, while Hsp90.beta. exists mainly as a monomer. From a functional perspective, Hsp90 participates in the folding, assembly, maturation, and stabilization of specific proteins as an integral component of a chaperone complex. Furthermore, Hsp90 is highly conserved between species; having 60% and 78% amino acids similarity between mammalian and the corresponding yeast and Drosophila proteins, respectively. Hsp90 is a highly conserved and essential stress protein that is expressed in all eukaryotic cells. Despite its label of being a heat shock protein, Hsp90 is one of the most highly expressed proteins in unstressed cells (1-2% of cytosolic protein). It carries out a number of housekeeping functions - including controlling the activity, turnover, and trafficking of a variety of proteins. Most of the Hsp90 - regulated proteins that have been discovered to date are involved in cell signalling. The number of proteins now known to interact with Hsp90 is about 100. Target proteins include the kinases v-Src, Wee1, and c-Raf, transcriptional regulators such as p53 and steroid receptors, and the polymerases of the hepatitis B virus and telomerase. |
