Transcriptional repressor (By similarity). Required for pronephric kidney development. At the 8-somite stage, expressed in the pronephros, with weak generalized expression elsewhere. At 24 hpf, expressed in the kidney tubules and the anterior duct, and also in the gut. At 60 hpf, expressed in the tubules and the pectoral fin buds. Embryos show a down-regulation of early pronephric markers lhx1a/lim1 and pax2a/pax2.1, and subsequent defects in renal structures. In addition, embryos at 72 hpf display pericardial edemas and kidney cysts characteristic of kidney failure. Belongs to the Odd C2H2-type zinc-finger protein family.
