DescriptionAnti-PER2, clone 7H4.1 Antibody
Alternate Names
  • PER2
  • Period circadian protein homolog 2
  • hPER2
  • Circadian clock protein PERIOD 2
Background InformationPeriod circadian protein homolog 2 (PER2), or Circadian clock protein PERIOD2, is a component of the circadian clock mechanism which is essential for generating circadian rhythms. It is a negative element in the circadian transcriptional loop by Influencing clock function by interacting with other circadian regulatory proteins and transporting them to the nucleus. PER2 negatively regulates CLOCK NPAS2-BMAL1 BMAL2-induced transactivation. This gene is a member of the Period family of genes and is expressed in a circadian pattern in the suprachiasmatic nucleus, the primary circadian pacemaker in the mammalian brain. Genes in this family encode components of the circadian rhythms of locomotor activity, metabolism, and behavior.
