GLI1 Antibody – Rabbit Polyclonal

This gene encodes a member of the Kruppel family of zinc finger proteins. The encoded transcription factor is activated by the sonic hedgehog signal transduction cascade and regulates stem cell proliferation. The activity and nuclear localization of this protein is negatively regulated by p53 in an inhibitory loop. Multiple transcript variants encoding different isoforms have been found for this gene.

GLI1: Acts as a transcriptional activator. May regulate the transcription of specific genes during normal development. May play a role in craniofacial development and digital development, as well as development of the central nervous system and gastrointestinal tract. Mediates SHH signaling and thus cell proliferation and differentiation. Interacts with KIF7. Interacts with ZIC1; the interaction enhances transcription activation. Amplified in glioblastoma cells. Testis, myometrium and fallopian tube. Also expressed in the brain with highest expression in the cerebellum, optic nerve and olfactory tract. Belongs to the GLI C2H2-type zinc-finger protein family. 2 isoforms of the human protein are produced by alternative splicing.
