PA1-524 detects PER1 from human and mouse tissues as well as recombinant mouse PER1.
PA1-524 has been sucessfully used in Western blot, immunofluoresence and immunohistochemistry procedures. By Western blot, this antibody detects an ~136 kDa protein representing overexpressed recombinant mouse PER1 protein. Immunofluorescence staining of PER1 in mouse testes with PA1-524 results in cytoplasmic staining.
PA1-524 immunizing peptide corresponds to amino acid residues 39-51 from mouse PER1. PA1-524 immunizing peptide (Cat. # PEP-076) is available for use in neutralization and control experiments.
Circadian rhythmicity is a basic property of phylogenetically diverse organisms which range from animals and plants, to fungi. Regulation of endogenous biological clocks is regulated at the genetic level by a protein-mediated, autoregulatory feed-back loop. 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. Transactivation of CLOCK-induced genes is mediated via an E box enhancer (CACGTG) found upstream of target genes. CLOCK-ARNT3 heterodimers bind to E box regulatory elements and stimulate gene transcription. CLOCK has been shown to transactivate the mammalian homolog of Drosophila per. 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.
