General annotation (Comments)

Function

ARNTL2-CLOCK heterodimers activate E-box element (3'-CACGTG-5') transcription. Also, in umbilical vein endothelial cells, activates SERPINE1 through E-box sites. This transactivation is inhibited by PER2 and CRY1.

Subunit structure

Component of the circadian core oscillator, which includes the CRY proteins, CLOCK, or NPAS2, ARNTL or ARNTL2, CSNK1D and/or CSNK1E, TIMELESS and the PER proteins. Interacts directly with CLOCK to form the ARNTL2-CLOCK transactivator. Can form heterodimers or homodimers which interact directly with CLOCK to form the transcription activator. Also interacts with NPAS2 and HIF1A.

Subcellular location

Nucleus.

Tissue specificity

Expressed in fetal brain. Highly expressed in brain and placenta. Lower levels in heart, liver, thymus, kidney and lung. Located to endothelial cells and neuronal cells of the suprachiasmatic nucleus (SCN). Also detected in endothelial cells of the heart, lung and kidney. In the brain, specifically expressed in the thalamus, hippocampus and amygdala.

Induction

Constitutively expressed. Has no circadian rhythm expression pattern.

Sequence similarities

Contains 1 basic helix-loop-helix (bHLH) domain.

Contains 1 PAC (PAS-associated C-terminal) domain.

Contains 2 PAS (PER-ARNT-SIM) domains.
