該基因編碼一種屬于gli家族c2h2型鋅指蛋白亞類的蛋白質。這個亞類的成員被描述為通過鋅指基序結合dna的轉錄因子。這些基序包含保守的h-c鏈。gli家族鋅指蛋白是聲刺猬（sonic hedgehog，shh）信號傳導的介質，在胚胎癌細胞中作為有效的癌基因存在。該基因編碼的蛋白質定位于細胞質并激活果蠅同源基因（ptch）的表達。它也被認為在胚胎發生過程中起作用。編碼蛋白與多種表型相關-格雷格頭足綜合征、帕利斯特-霍爾綜合征、前軸多指畸形IV型、后軸多指畸形A1和B型。[由Refseq提供，2008年7月]
This gene encodes a protein which belongs to the C2H2-type zinc finger protein subclass of the Gli family. Members of this subclass are characterized as transcription factors which bind DNA through zinc finger motifs. These motifs contain conserved H-C links. Gli family zinc finger proteins are mediators of Sonic hedgehog (Shh) signaling and they are implicated as potent oncogenes in the embryonal carcinoma cell. The protein encoded by this gene localizes to the cytoplasm and activates patched Drosophila homolog (PTCH) gene expression. It is also thought to play a role during embryogenesis. The encoded protein is associated with several phenotypes- Greig cephalopolysyndactyly syndrome, Pallister-Hall syndrome, preaxial polydactyly type IV, postaxial polydactyly types A1 and B.
