May be involved in transcriptional regulation. Widely expressed with highest levels in kidney, spleen and ovary. Highly expressed in the initial stages of development (4-cell up to 1k-2k cell stages). Expression slightly increases again between 24 hours and 5 dpf and after 20 dpf. Up-regulated during regeneration of the caudal fin after amputation. Belongs to the krueppel C2H2-type zinc-finger protein family.
