美国加州大学欧文分校的保罗·萨松-科西教授及同事曾于去年发现了触发生理节奏的基因CLOCK。基因CLOCK编码一种酶能够对染色质进行修正。最近他们发现这种酶的“伙伴”BMAL1蛋白上的单个氨基酸经过修改会触发与生理节奏有关的遗传事件。研究人 Paul Sasson-Cossy at the University of California, Irvine and his colleagues discovered last year that the gene rhythms CLOCK. The gene CLOCK encodes an enzyme that modifies chromatin. Recently, they found that a single amino acid on the “partner” BMAL1 protein of this enzyme has been modified to trigger circadian rhythms.
