Protocols

Specificity / Sensitivity

GLI1 Antibody detects endogenous levels of total GLI1 protein.

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Gly420 of human GLI1. Antibodies are purified by protein A and peptide affinity chromatography

Western Blotting

Western Blotting

Western blot analysis of total cell lysates from A549 and RMS-13 cells using GLI1 Antibody.

Background

GLI was first identified as a gene amplified in a malignant glioma (1) capable of transforming primary cells in cooperation with adenovirus E1A (2). GLI belongs to the Kruppel family of zinc finger proteins that includes three mammalian GLI proteins: GLI1, GLI2, and GLI3 (3). These GLI proteins are similar to the Drosophila homolog Cubitus interruptus (Ci) and function as transcription factors activated by the Hedgehog signaling pathway. Hedgehog signaling plays an important role in animal development, and research studies have shown that this pathway is aberrantly activated in many types of cancers (4,5).

GLI1 itself is a transcriptional target of the Hedgehog signaling pathway (6-8) and is used as a marker of Hedgehog signaling activation in cancer research (9,10).
