MGI Phenotype FUNCTION: 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. This gene is upregulated by Clock/Arntl heterodimers but then represses this upregulation in a feedback loop using Per/Cry heterodimers to interact with Clock/Arntl. Polymorphisms in this gene may increase the risk of getting certain cancers. Two transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Jan 2014]
PHENOTYPE: Homozygous null mice display a persistent circadian rhythm, but they have a shorter period and their ability to maintain the precision and the stability of the period is impaired. [provided by MGI curators]

Nature of Mutation

DNA sequencing using the SOLiD technique identified identified a T to G transversion at position 5074 in the Genbank genomic region NC_000077 for the Per1 gene on chromosome 11 (TTTACCCCAG ->TGTACCCCAG).  The mutation is located within intron 15, nine nucleotides upstream from the start of exon 16, and may impair the acceptor splice site of intron 15. Per1 contains 24 exons.  Multiple Per1 transcripts are displayed on Ensembl. The mutation has been confirmed by DNA sequencing using the Sanger method (Figure 1).

Protein Function and Prediction
Per1 encodes the 1291 amino acid rod period circadian protein homolog 1 (PER1). PER1 regulates the circadian clock by inhibiting CLOCK (Circadian Locomotor Output Cycles Kaput) activity. PER1 interacts with a number of proteins that are subunits of the circadian core oscillator, and regulates them by transporting them to the nucleus. PER1 undergoes ubiquitination and phosphorylation (Uniprot O35973). Mice homozygous for a knockout of the Per1 gene display a persistent circadian rhythm, but they have a shorter period and their ability to maintain the precision and the stability of the period is impaired.
