The present invention provides a novel telomere associated protein (Trf1-interacting nuclear protein 2 "Tin2") that hinders the binding of Trf1 to its specific telomere repeat sequence and mediates the formation of a Tin2-Trf1-telomeric DNA complex that limits telomerase access to the telomere. Also included are the corresponding nucleic acids that encode the Tin2 of the present invention, as well as mutants of Tin2. Methods of making, purifying and using Tin2 of the present invention are described. In addition, drug screening assays to identify drugs that mimic and/or complement the effect of Tin2 are presented.
