Functional Description
 ARNTL/2-CLOCK heterodimers activate E-box element (5'- CACGTG-3') transcription of a number of proteins of the circadian clock. Activates transcription of PER1 and PER2. This transcription is inhibited in a feedback loop by PER and CRY proteins. Has intrinsic histone acetyltransferase activity and this enzymatic function contributes to chromatin-remodeling events implicated in circadian control of gene expression (By similarity). Acetylates primarily histones H3 and H4 (By similarity). Acetylates also a non-histone substrate: ARNTL (By similarity). Plays a role in DNA damage response (DDR) signaling during the S phase.
