Sonic HedgeHog; also known as sonic hedgehog protein; belongs to the hedgehog family. It cannot be detected in adult tissues while can be found in fetal intestine; liver; lung; and kidney. Sonic HedgeHog is a protein that is vital in guding the early embryo. It has been associated as the major inductive signal in patterning of the ventral neural tube; the anterior-posterior limb axis; and the ventral somites. Sonic HedgeHog intercellular signal is essential for a various patterning events during development: signal produced by the notochord that induces ventral cell fate in the neural tube and somites; and the polarizing signal for patterning of the anterior-posterior axis of the developing limb bud. Sonic HedgeHog binds to the patched receptor; which functions in association with smoothened; to activate the transcription of target genes. In the absence of sonic HedgeHog; patched receptor represses the constitutive signaling activity of smoothened. Sonic HedgeHog also regulates another factor; the gli oncogene. Defects in sonic hedgehog can cause microphthalmia isolated with coloboma type 5; triphalangeal thumb-polysyndactyly syndrome and holoprosencephaly type 3.
