General annotation (Comments)

Subunit structure	Binds DNA specifically as homodimer or heterodimer with other PAR factors.
Subcellular location	Nucleus Probable.
Tissue specificity	Highly expressed in liver; lower levels in lund and kidney.
Induction	Accumulates according to a robust circadian rhythm By similarity.
