May play a role in neural and muscle differentiation. May be involved in transcriptional regulation. Expressed in brain, heart, lung, muscle and small intestine. No expression detected in undifferentiated P19 cells, however, expression was seen following retinoic acid treatment to induce neuronal differentiation. Expressed in undifferentiated C2C12 cells, following induction of muscle differentiation in a low-serum medium, expression levels were decreased. Highly expressed at day 7. Belongs to the krueppel C2H2-type zinc-finger protein family.
