1 Cisplatin differently affects amino terminal and carboxyl terminal domains of HSP90. Cisplatin heat shock protein 90 alpha family class A member 1 Homo sapiens
2 We previously demonstrated that the antineoplastic reagent, cisplatin, inhibits the aggregation prevention activity of mammalian HSP90. Cisplatin heat shock protein 90 alpha family class A member 1 Homo sapiens
3 We now show that cisplatin binds both the amino terminal and carboxyl terminal domains of the human HSP90 and differently affects these two domains. Cisplatin heat shock protein 90 alpha family class A member 1 Homo sapiens
4 In contrast, cisplatin induces a conformational change in HSP90N, but not HSP90C. Cisplatin heat shock protein 90 alpha family class A member 1 Homo sapiens
5 These results indicate that cisplatin modulates the HSP90 activities through two different mechanisms using the two distinct binding sites of the HSP90 molecule. Cisplatin heat shock protein 90 alpha family class A member 1 Homo sapiens
6 These results indicate that cisplatin modulates the HSP90 activities through two different mechanisms using the two distinct binding sites of the HSP90 molecule. Cisplatin heat shock protein 90 alpha family class A member 1 Homo sapiens
