Transcriptional repressor that binds the GZF1 responsive element (GRE) (consensus: 5'-TGCGCN[TG][CA]TATA-3'). May be regulating VSX2/HOX10 expression. Interacts with NCL. Predominantly nuclear. Expressed in several tissues, with highest levels in liver. Also expressed in embryos from 7 to 17 dpc. At 13.5-14.5 dpc, strong expression in ureteric buds (at protein level). Expression decreases in the kidney after birth (at protein level). Expressed in the eyes and limbs during development (at protein level). Belongs to the krueppel C2H2-type zinc-finger protein family.
