Summary: Enables several functions, including hedgehog family protein binding activity; hedgehog receptor activity; and phosphatidylinositol-4-phosphate binding activity. Involved in several processes, including Bolwig's organ morphogenesis; imaginal disc development; and regulation of signal transduction. Located in basal plasma membrane; cilium; and endocytic vesicle. Is integral component of plasma membrane. Colocalizes with fusome. Is expressed in several structures, including anterior-posterior subdivision of organism; eye-antennal disc; gonad; gut section; and presumptive embryonic/larval system. Used to study neurodegenerative disease. Human ortholog(s) of this gene implicated in basal cell carcinoma; holoprosencephaly; holoprosencephaly 7; medulloblastoma; and nevoid basal cell carcinoma syndrome. Orthologous to human PTCH1 (patched 1) and PTCH2 (patched 2). [provided by Alliance of Genome Resources, Apr 2022]

Polarized sorting of Patched enables cytoneme-mediated Hedgehog reception in the Drosophila wing disc.
Title: Polarized sorting of Patched enables cytoneme-mediated Hedgehog reception in the Drosophila wing disc.
SHH-Patched signal transduction is instrumental for development in Drosophila and for tumor cells communication in humans.
Title: Soluble Heparin and Heparan Sulfate Glycosaminoglycans Interfere with Sonic Hedgehog Solubilization and Receptor Binding.
Patched and Ihog activity are mutually required for receptor endocytosis and degradation, triggered by Hedgehog protein binding, and causing reduced levels of Ihog/Boi proteins in a stripe of cells at the anterior/posterior compartment boundary of the wing imaginal disc.
Title: Hedgehog mediated degradation of Ihog adhesion proteins modulates cell segregation in Drosophila wing imaginal discs.
a mutation of the PTC PY motif, which mediates binding of C2-WW-HECT family members, inhibits its internalization but not its autonomous and non-autonomous signalling activities. the two related UB-C2-WW-HECT ligases NEDD4 and SU(DX) regulate PTC trafficking and finely tune its accumulation through partially redundant but distinct functions
Title: Control of the dynamics and homeostasis of the Drosophila Hedgehog receptor Patched by two C2-WW-HECT-E3 Ubiquitin ligases.
Kto-Skd affects the A/P-axial development of the whole wing disc. Kto can interact with Cubitus interruptus (Ci), bind to the Ci-binding region on ptc promoter, which are both regulated by Hh signals to down-regulate ptc expression.
Title: The Kto-Skd complex can regulate ptc expression by interacting with Cubitus interruptus (Ci) in the Hedgehog signaling pathway.
in vivo study demonstrates that the PI3K-cIII complex is essential for downregulating Patched via the endosomal-lysosomal pathway to execute axon pruning
Title: The PI3K class III complex promotes axon pruning by downregulating a Ptc-derived signal via endosome-lysosomal degradation.
Ihog and Boi elicit Hh signaling via Ptc but do not aid Ptc in sequestering the Hh ligand
