Telomerase repressor proteins and nucleic acid compositions encoding the same are provided. The subject repressor proteins bind to a repressor site in the TERT minimal promoter, e.g., a Site C site, and thereby inhibit TERT expression. Also provided are methods of modulating, e.g., inhibiting or enhancing,...http://www.google.com/patents/US7211435?utm_source=gb-gplus-sharePatent US7211435 - Telomerase expression repressor proteins and methods of using the same
