요약정보
In a joint project‚ a team of researchers from Korea Advanced Institute of Science and Technology and Northwestern University have found a new gene that regulates the daily biological clock‚ also known as circadian rhythm.
[Interview : Choi Joon-ho‚ Professor
KAIST] "We found a new gene regulating the circadian rhythm during translation and such a mechanism has not been reported before."
The scientists studied mutant fruit flies for four years and discovered the gene which they called 'gene twenty-four.'
In previous studies‚ genes were found to regulate the biological clock during the stage of the circadian rhythm called transcription‚ when RNA is produced from DNA.
But gene twenty-four comes into effect during the stage called translation‚ when proteins are synthesized from RNA.
Also‚ the study showed that the gene helps synthesize period proteins.
[Interview : Lee Jong-bin‚ Researcher
KAIST] "This new gene works to increase the synthesis of the period protein‚ which plays an important role in regulating the circadian clock in fruit flies."
This study revealed a new mechanism controlling the fruit fly circadian clock‚ and therefore is expected to help reduce problems regarding biological activities‚ including jet lag and sleeping and feeding patterns.
The research is published in the latest issue of the scientific journal‚ Nature.
