When not bound by Hh ligands, PTCH1 restrains the activity of Smo. The protein functions as a receptor protein for sonic hedgehog, desert hedgehog, and indian hedgehog proteins.
PTCH1 (Patched 1) is a gene that plays a crucial role in the Hedgehog signaling pathway, which is important for cell growth, differentiation, and tissue patterning during embryonic development. Mutations in the PTCH1 gene are associated with several types of cancer.
PTCH1 and PTCH2 act as tumor suppressors by maintaining control over Hedgehog signaling. Their loss—whether by mutation or reduced expression—leads to unchecked pathway activation, supporting cell proliferation and survival. Such abnormalities are associated with a more aggressive tumor phenotype and poorer clinical outcomes in cancers where the Hedgehog pathway is a driver of tumorigenesis.
