CLOCKBMAL1toimintaa

CLOCKBMAL1 is a protein-coding gene located on chromosome 19q13.3 in humans. It is a member of the CLOCK gene family, which includes CLOCK, BMAL1, NPAS2, and NPAS3. CLOCKBMAL1 plays a crucial role in the regulation of circadian rhythms, the internal biological clock that governs the sleep-wake cycle and other physiological processes.

The CLOCKBMAL1 gene encodes a protein that forms a heterodimer with the BMAL1 protein. This heterodimer, known as CLOCK:BMAL1, is a transcription factor that regulates the expression of numerous genes involved in circadian rhythms. It binds to E-box elements in the promoters of target genes, activating or repressing their transcription.

Mutations in the CLOCKBMAL1 gene have been associated with various disorders, including advanced sleep phase syndrome (ASPS), a condition characterized by an abnormally advanced sleep-wake cycle. Additionally, CLOCKBMAL1 has been implicated in the pathogenesis of certain cancers, as its dysregulation can contribute to tumor growth and progression.

Research on CLOCKBMAL1 continues to uncover its roles in other physiological processes, such as metabolism, immune function, and aging. Understanding the mechanisms by which CLOCKBMAL1 regulates these processes may lead to the development of novel therapeutic strategies for related disorders.
