FAMILY

CATEGORY

transcription factor

SUBCELLULAR LOCALIZATION	intracellular
	intracellular,cytoplasm
	intracellular,nucleus

basic FUNCTION	involved in the control of early neural differentiation
	involved in transcriptional control through a multi-protein complex during the development
	functioning as a transcriptional regulator, and important for embryonic and postnatal developments
	dosage-sensitive transcription factor affecting multiple molecular pathways, thus contributing to the complexity of the phenotypes associated with altered gene dosage
	bind nucleosomes and having low nuclear mobility, suggesting its ability modify chromatin and regulate gene expression
	a positive regulator of CLOCK and an important part of the
	circadian loop of transcription
