Acts as a transcriptional activator (PubMed: 19706761, PubMed: 10806483, PubMed: 19878745, PubMed: 24311597, PubMed: 24217340). Binds to the DNA consensus sequence 5′-GACCACCCA-3′ (PubMed: 2105456, PubMed: 8378770, PubMed: 24217340). Regulates the transcription of specific genes during normal development (PubMed: 19706761). Plays a role in craniofacial development and digital development, as well as development of the central nervous system and gastrointestinal tract. Mediates SHH signaling (PubMed: 19706761, PubMed: 28973407). Plays a role in cell proliferation and differentiation via its role in SHH signaling (PubMed: 11238441, PubMed: 28973407). [Isoform 2]: Acts as a transcriptional activator, but activates a different set of genes than isoform 1. Activates expression of CD24, unlike isoform 1. Mediates SHH signaling. Promotes cancer cell migration.
