翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク AANAT (gene) ： ウィキペディア英語版 AANAT (gene) ''AANAT'' is a gene that encodes an enzyme aralkylamine N-acetyltransferase. It is the key regulator of day-night cycle (circadian rhythm). It is found in all animals. In humans it is present on chromosome 17, in chimpanzees chromosome 17, in mouse and sheep chromosome 11, in rat chromosome 10, and in chicken chromosome 18.〔(【引用サイトリンク】url=http://www.ncbi.nlm.nih.gov/gene/?term=aanat )〕 == Function == The protein encoded by this gene belongs to the acetyltransferase superfamily. It is the penultimate enzyme in melatonin synthesis and controls the night/day rhythm in melatonin production in the vertebrate pineal gland. Melatonin is essential for the function of the circadian clock that influences activity and sleep. This enzyme is regulated by cAMP-dependent phosphorylation that promotes its interaction with 14-3-3 proteins and thus protects the enzyme against proteasomal degradation.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「AANAT (gene)」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
