'''Protein patched homolog 1''' (Ptch1) acts as receptor of [[Sonic Hedgehog]] protein (Shh) which is involved in formation of embryonic structures <ref>PMID:11001584</ref>. Embryogenesis is regulated by several pathways one of which is the Shh-Patch1-Gli all of which are highly conserved. | '''Protein patched homolog 1''' (Ptch1) acts as receptor of [[Sonic Hedgehog]] protein (Shh) which is involved in formation of embryonic structures <ref>PMID:11001584</ref>.
