(C) Southern blot analysis of DNA extracted from mouse tails. The upper band in each case represents the wild-type allele, and the lower band represents the targeted allele (see panel A). (B) Southern blot identification of the targeting event in ES cells. Horizontal filled boxes indicate the locations of probes used for Southern blotting. (A second Kozak consensus sequence present in exon 2 could begin translation at nt 523). Filled boxes represent putative coding regions based on translation from the first ATG with a Kozak consensus sequence at nt 358 of AF050182. Open boxes represent untranslated regions. Boxes represent exons, and the lines between the boxes indicate introns. Intron and exon structure is shown only for the first five exons (E1 to E5). Restriction sites introduced by the PGK-NEO cassette and used for Southern blot analysis were EcoRV (R5) and SpeI (S). The 5′ and 3′ arms of the targeting construct were ca. A 1.6-kb portion of the mPer3 gene was excised with EcoRI (R1), and a PGK-NEO cassette was inserted in the reverse orientation. (A) Schematic representation of the mPer3 gene, the targeting construct, and the targeted allele. MPer3 targeting construct and genotyping strategies. The results demonstrate that mPer3 is not necessary for circadian rhythms in mice. Locomotor activity rhythms in mPER3-deficient mice were grossly normal, but the circadian cycle length was significantly (0.5 h) shorter than that in controls. mPer3 transcripts were rhythmically expressed in the SCN and skeletal muscle of mice homozygous for the targeted allele, but the level of expression of the mutant transcript was lower than that in wild-type controls. Rhythmic expression of mPer1 and mPer2 RNAs in skeletal muscle also did not differ between mPER3-deficient and wild-type mice. mPer1, mPer2, mCry1, and Bmal1 RNA rhythms in the SCN did not differ between mPER3-deficient and wild-type mice. Western blot analysis confirmed the absence of mPER3-immunoreactive proteins in mice homozygous for the targeted allele.

Customize the display of enzyme sites, features, primers, ORFs, DNA colors, and more. To assess the role of mouse PER3 (mPER3) in the circadian timing system, we generated mice with a targeted disruption of the mPer3 gene. SnapGene is the easiest way to plan, visualize, and document your everyday molecular biology procedures. The basic helix-loop-helix-PAS proteins CLOCK and BMAL1 are positive regulators and drive the expression of the negative regulators CRY1 and CRY2, as well as PER1, PER2, and PER3. PER, in concert with the product of the mammalian timeless gene (TIM), negatively regulates its own transcription by blocking the activity of the CLOCK-BMAL1 transactivation complex.Neurons in the mammalian suprachiasmatic nucleus (SCN) contain a cell-autonomous circadian clock that is based on a transcriptional-translational feedback loop. CLOCK has been shown to transactivate the mammalian homolog of Drosophila per. CLOCK-ARNT3 heterodimers bind to E box regulatory elements and stimulate gene transcription. Transactivation of CLOCK-induced genes is mediated via an E box enhancer (CACGTG) found upstream of target genes. In mammals, several genes that encode members of the basic helix-loop helix (bHLH) PAS (PER-ARNT-SIM) transcription factor family have been shown to play a significant role in regulating circadian oscillations. Regulation of endogenous biological clocks is regulated at the genetic level by a protein-mediated, autoregulatory feed-back loop.
