Text-mined interactions from Literome

Lotz et al., J Biol Chem 2003 : In experiments with purified proteins, Aha1 but not Hch1 stimulated the intrinsic ATPase activity of Hsp90 5-fold ... In vivo experiments demonstrated that Aha1 and Hch1 contributed to efficient activation of the heterologous Hsp90 client protein v-Src
Meares et al., FEBS Lett 2004 : Furthermore, with IGF-1 stimulation Hsp90 inhibition increased p38 activation, produced additive activation of p90RSK, and slightly increased the duration of ERK1/2 activation
Siligardi et al., J Biol Chem 2004 : These data indicated that Sba1 and Aha1 regulate Hsp90 by influencing the conformational state of the `` ATP lid '' and consequent N-terminal dimerization, whereas Sti1 does not
Holmes et al., Cancer Res 2008 (Neoplasms) : As AHA1 increases the ATPase activity of HSP90 , we hypothesized that modulation of AHA1 expression could influence the activity of client proteins and/or the cellular response to 17-AAG
Koulov et al., Mol Biol Cell 2010 (Cystic Fibrosis) : Biological and structural basis for Aha1 regulation of Hsp90 ATPase activity in maintaining proteostasis in the human disease cystic fibrosis ... To elucidate the structural basis for ATPase stimulation of human Hsp90 by human Aha1 , we have developed novel mass spectrometry approaches that demonstrate that the N- and C-terminal domains of Aha1 cooperatively bind across the dimer interface of Hsp90 to modulate the ATP hydrolysis cycle and client activity in vivo
Desjardins et al., Arterioscler Thromb Vasc Biol 2012 : Finally, we show that overexpression of AHA1 in ECs promotes association of eNOS and Hsp90 , phosphorylation of Ser-1179 of eNOS, increases NO production, and cell migration
