Expression is strongest in the anterior Fol cells of the oikoplastic epithelium. Very weak expression observed in the oocyte. Strongest expression seen in early tadpole (2 hours posthatching) and at 4/5 days posthatching. N-terminal zinc-finger domains are similar to the Ikaros clan but may not have the same binding specificity. Key residues involved in binding to the consensus Ikaros target site (5'-GGGA-3'), found in the promoter regions have diverged. Belongs to the Ikaros C2H2-type zinc-finger protein family.
