Canonical activation of HH-GLI signaling. In absence of the HH ligand (A), PTCH inhibits SMO, and therefore GLI2 and GLI3 are phosphorylated by PKA, CK1 and GSK3β, which create binding sites for the E3 ubiquitin ligase β-TrCP.GLI3 and GLI2 undergo partial proteasome degradation, leading to the formation of repressor forms (GLI3/2 R), that …

Web15 Apr 2011 · Two distinct mechanisms are responsible for inappropriate and uncontrolled Hh pathway activation in human malignancies: ligand-dependent, due to over-expression of Hh ligand, and ligand-independent, resulting from genetic mutations in pathway components such as Patched (Ptch) and Smoothened (Smo).
WebThe HH pathway, and in particular the protein Smoothened (SMO), has been shown to be essential for regulating stem cell fate in chronic myeloid leukemia (CML). ... Exposure to the HH ligand mediates dissociation of GLI-SUFU complexes so that activated GLI proteins can translocate to the nucleus where they promote the transcription of HH pathway ... Web6 Feb 2024 · The Hedgehog (HH) ligands are evolutionarily conserved morphogens that are critical for development. They bind to and block the activity of the membrane protein Patched (Ptc or PTCH), which relieves its repression of the G protein–coupled receptor (GPCR)–like protein Smoothened (Smo).
