Background

BMAL1 (brain and muscle ARNT-like 1; ARNTL) is an essential core component in circadian clock machinery which is regulatory mechanism for circadian rhythms. Circadian clock genes include three period proteins (PER1, PER2 and PER3), two cryptochromes (CRY1 and CRY2), CLOCK, NPAS2 and BMAL proteins, wherein BMAL1 has a potential to heterodimerize with CLOCK or NPAS2 genes; and this neocomplex drives transcription from E-box elements (5'-CACGTG-3') found in circadian-responsive genes's promoters. PER/CRY proteins negatively regulate CLOCK/BMAL1 dimer-mediated transcription, thereby forming the feedback loop that regulates the timing of clock gene transcription. BMAL1 also associates with GNB2L1/RACK1 and PRKCA in a nuclear complex, whertein GNB2L1 and PRKCA are recruited to the complex in a circadian manner. BMAL1 undergoes acetylation (Lys-538), phosphorylation and sumoylation (Lys-259) upon dimerization with CLOCK and acetylation facilitates CRY1-mediated repression. CLOCK-BMAL1 double mutations within PAS domains leads to syngernistic desensitization to high levels of CRY on repression of CLOCK-BMAL1 transcriptional activity of PER1 and, disrupt circadian rhythmicity. Clock genes functions primarily as tumor suppressors and their abbarant expression is observed in malignant pleural mesothelioma, colorectal and breast cancer.
