A novel protein interacts with a clock-related protein, rPer1.


Mammalian Per proteins are thought to be important in the mechanism of circadian rhythm. We identified a novel protein PIPS (Per1 interacting protein of the suprachiasmatic nucleus) with the yeast two-hybrid system using PAS domain of rat Per1 (rPer1) as a bait. PIPS is about a 180-kDa protein and expressed mainly in the brain, especially in the… (More)
