Similar heat shock proteins were later discovered in bacterial chicken and mammalian cells, and have been subsequently studied in other organisms. A series of proteins including HSP 90, HSP 70, HSP 20-30 and ubiquitin are induced by insults such as temperature shock, chemicals and other environmental stress. A major function of HSP 90 and other HSPs is to act as molecular chaperones. HSP 90 forms a complex with glucocorticoid receptor (GR), rendering the non ligand-bound receptor transcriptionally inactive. HSP 90 binds the GR as a heterocomplex composed of either HSP 56 or Cyclophilin D, forming an aporeceptor comiplex. HSP 90 also exists as a dimer with other proteins such as p60\/sti1 and p23, forming an apo-receptor complex with estrogen and androgen receptors.\u003c\/p\u003e","brand":"NSJ Bioreagents","offers":[{"title":"100 ug","offer_id":51548631990552,"sku":"V4367-100UG","price":559.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/get_image_5d80f863-7685-446b-b588-8745bbaf78ea.jpg?v=1768284888","url":"https:\/\/danabiosci.com\/products\/nsj-v4367-100ug","provider":"Dana Bioscience","version":"1.0","type":"link"}
