Recombinant Human CHRONO Protein

Product Name: Recombinant Human CHRONO Protein
Catalog #:  HTF-1409
Manufacture:  LD Biopharma, Inc.

Human circadian-associated transcriptional repressor (CHRONO) is a transcriptional repressor which inhibits the transcriptional activator activity of the CLOCK-ARNTL / BMAL1 heterodimer (circadian clock) to regulate the phase of circadian gene expression. Its expression levels peak at circadian time 12 hours (CT12), 8 hours earlier than the peak of PER1/2 and CRY1/2 transcriptional repressors (peak CT20-CT24). Thus, it can repress the CLOCK-ARNTL/BMAL1 activity in a different time window compared to CRY and PER proteins. As ARNTL/BMAL1 complex positively regulates myogenesis and negatively regulates adipogenesis via the transcriptional control of the genes of the canonical Wnt signaling pathway. CHRONO may also plays a role in normal pancreatic beta-cell function; regulates glucose-stimulated insulin secretion via interaction of ARNTL/BMAL1 complex.

Full-length mature human CHRONO ( 384 aa, derived from BC027999 ) gene was constructed with 29 aa N-terminal T7 / His / TEV cleavage site Tag. This protein was expressed in E. coli as inclusion bodies, refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.
