Transcription repressor. Involved in the development of the forebrain region. Expressed during mid/late-gastrulation at the rostro-medial regions of the anterior neural plate. Expression becomes more pronounced as neurulation progresses and remains localized within the prospective telencephalic region. By stage 46, expressed in the olfactory bulbs, nervus terminalis, ventral hypothalamic nucleus, and ventricular zone. Belongs to the krueppel C2H2-type zinc-finger protein family.
