CC -!- FUNCTION: ACTS AS A RECEPTOR FOR SONIC HEDGEHOG (SHH), INDIAN CC HEDGEHOG (IHH) AND DESERT HEDGEHOG (DHH). ASSOCIATES WITH THE CC SMOOTHENED PROTEIN (SMO) TO TRANSDUCE THE HEDGEHOG'S PROTEINS CC SIGNAL. SEEMS TO HAVE A TUMOR SUPPRESSOR FUNCTION, AS INACTIVATION CC OF THIS PROTEIN IS PROBABLY A NECESSARY, IF NOT SUFFICIENT STEP CC FOR TUMORIGENESIS. CC -!- SUBCELLULAR LOCATION: INTEGRAL MEMBRANE PROTEIN. CC -!- TISSUE SPECIFICITY: IN THE ADULT, EXPRESSED IN BRAIN, LUNG, LIVER, CC HEART, PLACENTA, SKELETAL MUSCLE, PANCREAS AND KIDNEY. EXPRESSED CC IN TUMOR CELLS BUT NOT IN NORMAL SKIN. CC -!- DEVELOPMENTAL STAGE: IN THE EMBRYO, FOUND IN ALL MAJOR TARGET CC TISSUES OF SONIC HEDGEHOG, SUCH AS THE VENTRAL NEURAL TUBE, CC SOMITES, AND TISSUES SURROUNDING THE ZONE OF POLARIZING ACTIVITY CC OF THE LIMB BUD. CC -!- PTM: GLYCOSYLATION IS NECESSARY FOR SHH BINDING (BY SIMILARITY). CC -!- DISEASE: DEFECTS IN PTCH ARE PROBABLY THE CAUSE OF BASAL CELL CC NEVUS SYNDROME (BCNS), ALSO CALLED GORLIN SYNDROME OR GORLIN-GOLTZ CC SYNDROME; AN AUTOSOMAL DOMINANT DISEASE CHARACTERIZED BY NEVOID CC BASAL CELL CARCINOMAS (NBCCS) AND DEVELOPMENTAL ABNORMALITIES SUCH CC AS RIB AND CRANIOFACIAL ALTERATIONS, POLYDACTYLY, SYNDACTYLY, AND CC SPINA BIFIDA. IN ADDITION, THE PATIENTS SUFFER FROM A MULTITUDE OF CC TUMORS LIKE BASAL CELL CARCINOMAS (BCC), FIBROMAS OF THE OVARIES CC AND HEART, CYSTS OF THE SKIN, JAWS AND MESENTERY, AS WELL AS CC MEDULLOBLASTOMAS AND MENINGIOMAS. COULD ALSO BE ASSOCIATED WITH CC LARGE BODY SIZE OBSERVED IN BCNS PATIENTS. CC -!- SIMILARITY: BELONGS TO THE PATCHED FAMILY.
