Arylalkylamine N-acetyltransferase: "the Timezyme".
Arylalkylamine N-acetyltransferase controls daily changes in melatonin production by the pineal gland and thereby plays a unique role in biological timing in vertebrates. Arylalkylamine N-acetyltransferase is also expressed in the retina, where it may play other roles in addition to signaling, including neurotransmission and detoxification. Large changes in activity reflect cyclic 3',5'-adenosi...
متن کامل[Circadian rhythms and light responses of clock gene and arylalkylamine N-acetyltransferase gene expressions in the pineal gland of rats].
This study was to investigate the circadian rhythms and light responses of Clock gene and arylalkylamine N-acetyltransferase (NAT) gene expressions in the rat pineal gland under the 12 h-light : 12 h-dark cycle condition (LD) and constant darkness (DD). Sprague-Dawley rats housed under the light regime of LD (n=36) for 4 weeks and of DD (n=36) for 8 weeks were sampled for the pineal gland once ...
متن کاملRetinal melatonin production: role of proteasomal proteolysis in circadian and photic control of arylalkylamine N-acetyltransferase.
PURPOSE Dynamic day-night changes in melatonin synthesis are regulated by changes in the activity of serotonin N-acetyltransferase (arylalkylamine N-acetyltransferase [AA-NAT]). Similarly, a light-induced decrease in AA-NAT activity at night rapidly suppresses melatonin synthesis. The purpose of the current study was to test the hypothesis that in vivo changes of AA-NAT activity in chicken reti...
متن کاملArylamine N-acetyltransferase and arylalkylamine N-acetyltransferase in the mammalian pineal gland.
Amine N-acetylation in the pineal gland is of special importance because it is the first step in the synthesis of melatonin from serotonin. In the present study the N-acetylation of arylamines and arylalkylamines by homogenates of rat and sheep pineal glands was investigated. The arylamines studied were p-phenetidine and aniline; the arylalkylamines studied were tryptamine, serotonin, 5-methoxy...
متن کاملCircadian expression of clock and putative clock-controlled genes in skeletal muscle of the zebrafish.
To identify circadian patterns of gene expression in skeletal muscle, adult male zebrafish were acclimated for 2 wk to a 12:12-h light-dark photoperiod and then exposed to continuous darkness for 86 h with ad libitum feeding. The increase in gut food content associated with the subjective light period was much diminished by the third cycle, enabling feeding and circadian rhythms to be distingui...
