PTCH1 : patched 1
Description
The PTCH1 gene encodes a transmembrane protein that acts as a receptor for the Hedgehog (Hh) signaling pathway. This pathway plays a crucial role in embryonic development, tissue regeneration, and maintaining adult tissue homeostasis. PTCH1 functions as a tumor suppressor, inhibiting Hh signaling in the absence of Hh ligands. Upon binding to Hh ligands, PTCH1 releases its inhibition on the downstream signaling cascade, leading to the activation of gene transcription. Mutations in PTCH1 can lead to uncontrolled Hh signaling, contributing to the development of various cancers and developmental disorders.
