Timeless - timeless circadian clock 1 Gene

The protein encoded by this gene is highly conserved and is involved in cell survival after damage or stress, increase in DNA Polymerase epsilon activity, maintenance of telomere length, and epithelial cell morphogenesis. The encoded protein also plays a role in the circadian rhythm autoregulatory loop, interacting with the PERIOD genes (PER1, PER2, and PER3) and Others to downregulate activation of PER1 by CLOCK/ARNTL. Changes in this gene or its expression may promote prostate Cancer, lung Cancer, breast Cancer, and mental disorders. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Feb 2014]
