Acts as a transcriptional activator. May regulate the transcription of specific genes during normal development. May play a role in craniofacial development and digital development, as well as development of the central nervous system and gastrointestinal tract. Mediates SHH signaling and thus cell proliferation and differentiation. Interacts with KIF7. Interacts with ZIC1; the interaction enhances transcription activation. Amplified in glioblastoma cells. Testis, myometrium and fallopian tube. Also expressed in the brain with highest expression in the cerebellum, optic nerve and olfactory tract. Belongs to the GLI C2H2-type zinc-finger protein family. 2 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
