Human cancers utilise telomerase to maintain telomeres and prohibit cell senescence. Human telomerase reverse transcriptase (hTERT), an essential component of this complex, is regulated at the level of gene transcription. Using SILAC‐proteomic analysis and molecular studies, we identified the AAA+ ATPase, RuvBl2 as a transcriptional regulator of hTERT and established that this regulation is through cooperation with Ets‐2. In colon cancer patients, nuclear expression of RuvBl2 associated with nuclear expression of hTERT, pEts2 and advanced nodal disease (P < 0.01, P = 0.05 and P = 0.03 respectively, n = 170). These data firmly implicate RuvBl2 in Ets2 mediated regulation of hTERT in colon cancer which has functional and clinical consequences.
