Abstract
Protein complexes are provided comprising survivin and one or more proteins selected from the group consisting of HDLC1, beta-actin, DNA helicase II, COPP, OSTP, SLC8A1, A2-CAT. The protein complexes are useful in screening assays for identifying compounds effective in modulating the protein complexes and in treating and/or preventing diseases and disorders associated with survivin and its interacting partner proteins. In addition, methods of detecting the protein complexes and modulating the functions and activities of the protein complexes or interacting members thereof are also provided.
