Do you have a biological clock?
December 12, 2007 5:26pm CST
The chemical switch that activates the genetic mechanism regulating the body's internal clock has been identified by University of California. This new development will allow new drugs to treat sleep disorders and related problems. A modification in a single amino acid in the BMAL1 protein activates the genetic processes involved with circadian rhythms. If this amino acid modification goes awry, the genetic switching mechanism can malfunction, resulting in circadian rhythm-related disorders. For more info, consult the Dec. 13 issue of Nature.
