Aryl hydrocarbon receptor nuclear translocator-like 2, also known as Mop9[1], Bmal2[2], CLIF[3], or ARNTL2, is a gene.

Arntl2 is a mammalian paralog (with ARNTL) of the Drosophila Cycle gene, and interacts with both Clock and NPAS2 to bind to E-box sequences in regulated promoters and activate their transcription[1]. Although Arntl2 is not required for normal function of the mammalian circadian oscillator, it may play an important role in mediating the output of the circadian clock. Perhaps because of this, there is relatively little published literature on the role of Arntl2 in regulation of physiology.

Arntl2 is a candidate gene for human type 1 diabetes[4].

In over expression studies, Arntl2 forms a heterodimer with Clock to regulate E-box sequences in the Pai-1 promoter[3]. Recent work suggest that this interaction may be in concert with Arntl/Clock heterodimeric complexes[5].
