Target description

Period circadian protein homolog 2 (UniProt: O15055; also known as hPER2, Circadian clock protein PERIOD 2, PER2) is encoded by the PER2 (also known as KIAA0347) gene (Gene ID: 8864) in human. PER2 is a homodimeric protein that is widely expressed and is high levels are found in skeletal muscle and pancreas. It serves as a transcriptional repressor and is a core component of the circadian clock along with other clock components (CLOCK, NPAS2, ARNTL/BMAL1, ARNTL2/BMAL2, PER1, PER2, PER3, CRY1 and CRY2) it plays a critical role in rhythm generation. Its levels oscillate diurnally, and its rhythmic levels are critical for the generation of circadian rhythms in central as well as peripheral clocks. Transcription factors, CLOCK or NPAS2 and ARNTL/BMAL1 or ARNTL2/BMAL2, form the positive limb of the feedback loop, act in the form of a heterodimer and activate the transcription of core clock genes and clock-controlled genes. The core clock genes: PER1/2/3 and CRY1/2 which are transcriptional repressors form the negative limb of the feedback loop and interact with the CLOCK/NPAS2, ARNTL/BMAL1, ARNTL2/BMAL2 heterodimer inhibiting its activity. PER2 shuttles between the nucleus and cytoplasm and this shuttling is affected by interaction with other circadian core oscillator proteins and/or by phosphorylation. It translocates to the nucleus after phosphorylation by CSNK1D or CSNK1E. PER2 contains a nuclear localization signal (aa 789-805) and three nuclear export signals (aa 111-120, 462-471, and 989-996). Mutations in PER2 gene have been linked to advanced sleep phase syndrome. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
