GLI1

GLI1 is a protein that in humans is encoded by the GLI1 gene. It is a member of the C2H2-type zinc finger protein subclass of the Gli family. GLI1 is a key mediator of the Sonic hedgehog signaling pathway and has been implicated in the development and progression of several human cancers.

Function

GLI1 functions as a transcriptional activator that binds to the 5' flanking region of target genes. The role of this protein in embryonic development and tumorigenesis has been extensively studied. It is involved in the processes of cell growth, survival, and the development of various tissues and organs.

Clinical significance

Alterations in the GLI1 gene have been associated with several types of cancer, including basal cell carcinoma, medulloblastoma, and rhabdomyosarcoma. In these cancers, GLI1 is often overexpressed, leading to increased cell proliferation and survival. Inhibitors of GLI1 are currently being investigated as potential cancer therapeutics.
