Gli family zinc finger protein (GLI family proteins comprise GLI1, GLI2, and GLI3) (GLI (GLI1, GLI2, GLI3 for individual proteins))

The Gli family zinc finger proteins (GLI1, GLI2, GLI3) are a group of transcription factors that act as key downstream effectors of the Hedgehog (Hh) signaling pathway. They contain highly conserved C2H2 zinc finger DNA-binding domains, which facilitate direct binding to the promoters of target genes to regulate gene transcription in response to Hh signal gradients. GLI1 functions primarily as a transcriptional activator, GLI2 and GLI3 have both activator and repressor domains, and these proteins collectively interpret Hh signaling into genetic and cellular responses critical for embryogenesis, stem cell maintenance, and carcinogenesis. Aberrant activation or mutation of GLI family members is implicated in various cancers and genetic developmental disorders, making them both diagnostic biomarkers and therapeutic targets in oncology and developmental genetics.
