Abstract

We have identified novel mammalian homologues of a Drosophila clock gene, timeless, and designated them as human TIMELESS1 (hTIM1) and mouse Timeless1 (mTim1), respectively. These genes were mapped by FISH to chromosomal regions 12q12-13 in human and 10D3 in mouse. The deduced amino acid sequences of hTim1 and mTim1 proteins were 1208 and 1197 amino acids in length and shared 83% identity. Northern blot analysis identified a single transcript of 4.5 kb expressed widely in many tissues examined. Unlike the Drosophila counterpart, the levels of the mTim1 transcript exhibited no prominent circadian oscillation in the mouse brain.
