背景信息

**Background of CRY1 Recombinant Protein**

Cryptochrome 1 (CRY1) is a member of the cryptochrome protein family, which plays a critical role in regulating circadian rhythms in mammals. As a core component of the molecular clock, CRY1 interacts with other clock proteins, such as CLOCK and BMAL1. to repress their transcriptional activity, thereby maintaining the 24-hour oscillatory cycle of gene expression. Beyond circadian regulation, CRY1 is involved in light-dependent and light-independent functions, including DNA repair and cellular stress responses.

Recombinant CRY1 protein is engineered through genetic engineering techniques, where the CRY1 gene is cloned into expression vectors and produced in heterologous systems like *E. coli* or mammalian cell cultures. This allows for large-scale production of purified, functional CRY1 protein for research and therapeutic applications.

The study of recombinant CRY1 has advanced our understanding of circadian biology and its links to diseases like sleep disorders, metabolic syndromes, and cancer. It serves as a tool for structural studies (e.g., crystallography), biochemical assays (e.g., protein-protein interaction analyses), and drug discovery targeting circadian rhythm-related pathologies. Additionally, recombinant CRY1 aids in exploring post-translational modifications (e.g., phosphorylation) that regulate its stability and activity.

Despite progress, challenges remain in elucidating CRY1's dual roles in circadian and non-circadian pathways. Research using recombinant CRY1 continues to uncover its molecular mechanisms, offering potential therapeutic strategies for disorders linked to clock dysregulation.
