Telomerase

http://en.wikipedia.org/wiki/Telomerase

‎""Telomerase was discovered because of its ability to elongate and maintain telomeric DNA, and almost all telomerase research has been posited on the notion that its functions are confined to this crucial function. However, in recent years it has become apparent that telomerase exerts functions that are relevant to cell proliferation but unrelated to telomere maintenance" (Hanahan & Weinberg, 2011).
