Probably acts as a transcriptional activator. May bind to the minimal GLI-consensus sequence 5'-GGGTGGTC-3'. Can determine the ectodermal cell fate and promote the earliest step of neural and neural crest development. Involved in establishing left-right asymmetry in the embryo (By similarity). The C2H2-type 3, 4 and 5 zinc finger domains are necessary for transcription activation. The zinc fingers and the N-terminus are independently important for establishing the L/R axis (By similarity). Belongs to the GLI C2H2-type zinc-finger protein family.
