... the drug did not inhibit GR nuclear export itself. This indicates the existence of a TPR-domain-dependent mechanism for the export of nuclear proteins. The expression balance of those TPR domain proteins bound to the GR–Hsp90 complex may determine the subcellular localization and nucleocytoplasmic...

Morgana deregulation promotes carcinogenesis in both mice and humans while, in Drosophila , loss of mora causes lethality and a complex mitotic phenotype that is rescued by a human morgana transgene. Here, we show that Drosophila...
