CC   -!- FUNCTION: Transcription factor which plays a key role in limb
CC       development. Positively regulates FGF8 expression in the apical
CC       ectodermal ridge (AER) and contributes to limb outgrowth in embryos.
CC       {ECO:0000269|PubMed:15358670}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000305}.
CC   -!- DEVELOPMENTAL STAGE: Detected in the forebrain, prospective
CC       midbrain/hindbrain boundary, tail bud, and neural keel and neural tube
CC       in the somitogenesis stages. Expressed in the pectoral fin bud, and the
CC       signal is restricted to the apical fold. {ECO:0000269|PubMed:15358670}.
CC   -!- DOMAIN: The 9aaTAD motif is a transactivation domain present in a large
CC       number of yeast and animal transcription factors.
CC       {ECO:0000250|UniProtKB:Q8IXZ3}.
CC   -!- SIMILARITY: Belongs to the Sp1 C2H2-type zinc-finger protein family.
CC       {ECO:0000305}.
