Gene: Per2 (period circadian clock 2) Mus musculus
Symbol: Per2
Name: period circadian clock 2
Description: Exhibits several functions, including enzyme binding activity; nucleic acid binding activity; and transcription factor binding activity. Involved in several processes, including gluconeogenesis; monocarboxylic acid metabolic process; and regulation of gene expression. Localizes to the nucleus and perinuclear region of cytoplasm. Used to study advanced sleep phase syndrome 1. Human ortholog(s) of this gene implicated in advanced sleep phase syndrome and advanced sleep phase syndrome 1. Is expressed in several structures, including alimentary system; genitourinary system; nervous system; respiratory system; and sensory organ. Orthologous to human PER2 (period circadian regulator 2).
Type: protein-coding
RefSeq Status: VALIDATED
Also known as: circadian clock protein PERIOD 2; mKIAA0347; mPer2; period 2; period circadian protein homolog 2; period homolog 2
