mouse ... Per1(18626)

General description

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. Circadian expression in the suprachiasmatic nucleus continues in constant darkness, and a shift in the light/dark cycle evokes a proportional shift of gene expression in the suprachiasmatic nucleus. The specific function of this gene is not yet known. Alternative splicing has been observed in this gene; however, these variants have not been fully described.

Specificity

Cat. # AB2201 will recognize the N-terminus of mPER1.
May react with Drosophila, Arvicanthis niloticus and Mesocricetus auratus based on sequence homology. Reactivity with other species has not been tested.

Application

Detect mPER1 (residues 6-21) using this Anti-mPER1 (residues 6-21) Antibody validated for use in WB.
Immunohistichemistry:
Tested on whole brain (SCN; peak staining at CT/ZT12). Optimium working dilutions need to be determined by end used.

Quality

Routinely tested by western blot on human brain lysate

Target description

136 kDa

In mammals, circadian clocks are strictly suppressed during early embryonic stages, as well as in pluripotent stem cells, by the lack of CLOCK/BMAL1-mediated circadian feedback loops. During ontogenesis, the innate circadian clocks emerge gradually at a late developmental stage, and

In mammals, the circadian system is composed of a principal circadian oscillator located in the suprachiasmatic nucleus (SCN) and a number of subordinate oscillators in extra-SCN brain regions and peripheral tissues/organs. However, how the time-keeping functions of this multiple oscillator
