Nucleic acid encoding an altered telomere repeat binding factor 2

摘要

The present invention provides an isolated altered vertebrate telomere repeat binding factor (A-TRFs). Also included are the corresponding nucleic acids that encode the A-TRFs of the present invention, as well as the heterodimers formed by the association of an A-TRF with a TRF. In addition, pharmaceutical compositions containing the A-TRFs for treatment of diseases such as ataxia telangiectasia are also included. Methods of making, purifying and using the A-TRFs of the present invention are described. In addition, drug screening assays to identify drugs that mimic and/or complement the effect of the A-TRFs are presented.
