Research Abstract |
We analyzed the effects of gaseous small molecules on function of NPAS2, a heme protein associated with mammalian circadian rhythms. The transcriptional activity and DNA binding activity of NPAS2 were affected in a concentration-dependent-manner by CO or NO, suggesting cross talk between circadian rhythm and CO-, NO-signaling system. The analysis of mutants revealed that specific amino-acid residues in the PASA heme domain are essential to signal transduction in the molecule.
