Transcription factor that can both act as an activator or a repressor depending on the context. Plays a central role in BMP signaling and olfactory neurogenesis. Associates with SMADs in response to BMP2 leading to activate transcription of BMP target genes. Acts as a transcriptional repressor via its interaction with EBF1, a transcription factor involved in terminal olfactory receptor neurons differentiation; this interaction preventing EBF1 to bind DNA and activate olfactory-specific genes. Involved in olfactory neurogenesis by participating in a developmental switch that regulates the transition from differentiation to maturation in olfactory receptor neurons. Controls proliferation and differentiation of neural precursors in cerebellar vermis formation. Homodimer. Interacts with PARP1, SMAD1 and SMAD4 (By similarity). Interacts with EBF1. Interacts with CEP290 (By similarity). Expressed in brain, eye, olfactory epithelium, spleen and heart. Expressed in the basal layer, consisting of neural precursor cells and immature sensory neurons of the olfactory epithelium, but not in the mature receptor cells. Uses different DNA- and protein-binding zinc fingers to regulate the distinct BMP-Smad and Olf signaling pathways. C2H2-type zinc fingers 14-19 mediate the interaction with SMAD1 and SMAD4, while zinc fingers 28-30 mediate the interaction with EBF1. zinc fingers 2-8 bind the 5'-CCGCCC-3' DNA sequence in concert with EBF1, while zinc fingers 9-13 bind BMP target gene promoters in concert with SMADs (By similarity). Belongs to the krueppel C2H2-type zinc-finger protein family.
