Pineal N-acetyltransferase (NAT) activity in the ground squirrel, a diurnal mammal, was found to have a daily fluctuation with peak activity during the dark time. This same daily change is found in nocturnal mammals and diurnal birds. NAT may play an important role in keeping track of light and dark cycles.
在昼行性哺乳动物地松鼠中,发现松果体N - 乙酰基转移酶(NAT)活性具有每日波动,在黑暗时期活性达到峰值。在夜行性哺乳动物和昼行性鸟类中也发现了相同的每日变化。NAT可能在追踪明暗周期方面发挥重要作用。
